  Hereinafter, a machining program editing apparatus, a machining program editing method, and a machining program editing program according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a diagram illustrating a configuration example of a machining program editing apparatus 1 according to the first embodiment of the present invention. As shown in FIG. 1, the machining program editing apparatus 1 according to the first embodiment has a function of editing a machining program executed by a numerical control device mounted on a machine tool (not shown). The numerical control device processes the workpiece by the machine tool by controlling each motor constituting the machine tool according to the information described in the machining program.

  As shown in FIG. 1, the machining program editing device 1 includes a storage unit 2, a processing unit 3, an input unit 4, and a display unit 5. The storage unit 2 stores a processing program 21 to be edited. The processing unit 3 reads at least a part of the plurality of blocks included in the machining program 21 stored in the storage unit 2 and displays the read block 5 on the display unit 5.

  Each block included in the machining program 21 includes a command for executing a machining procedure for the workpiece. The minimum command unit is called a word, and a word is composed of an address and data. The address is expressed in alphabets and the data is expressed in numbers. A block refers to a collection of words separated by delimiters. Since a delimiter is displayed at the end of a line or treated as a line break, a block means a character string of one line. In the following description, it is assumed that the delimiter is “;”. Lines with no character string are also handled as blocks. That is, a line that is in a state before the command is set is also handled as a block.

  An operator who edits the machining program 21 can give an instruction to the machining program editing apparatus 1 by performing an input operation on the input unit 4. The processing unit 3 moves the cursor indicating the current editing position based on the operator's instruction, and further edits the processing program by editing the block at the editing position based on the instruction from the operator.

  The storage unit 2 stores a machining program 21, a machine tool parameter 22, a usable command list 23, a modal command-command availability correspondence table 24, a block-by-block modal information 25, and a block-by-block command position information 26. To do.

  As described above, the machining program 21 includes a plurality of blocks for executing a machining procedure for a workpiece, and may be referred to as an NC (Numerical Control) program. The machining program 21 is a machining program composed of ISO / EIA codes, but may be a program other than ISO / EIA codes.

  The plurality of commands used in the machining program 21 includes a modal command and an unmodal command. A modal command is valid until another command in the same group is given once issued, and an unmodal command is valid only in the commanded block. A group is a set of commands having the same purpose. For example, “G0 positioning”, “G1 linear interpolation”, “G2 circular interpolation CW”, and “G3 circular interpolation CCW” having the same purpose of “movement” are the same group. It belongs to a later-described group “01”.

  In addition, the plurality of commands used in the machining program 21 include a command for controlling movement of a plurality of motors mounted on the machine tool. For example, the movement instruction to the motor named “X” is instructed by using “X” as an address and a numerical value representing a movement position or movement amount as data. These multiple movement commands include an absolute value command and an incremental value command. The absolute value command can command movement to an absolute command position, and the incremental value command can command movement by an increment from the command position in the previous block. The command position is a position commanded by a movement command.

  The machine tool parameter 22 includes a plurality of parameters used for executing the machining program 21. The plurality of parameters include a parameter indicating the type of machine tool and a parameter defining an initial state of a modal command.

  The usable command list 23 includes a usable command list 27 for each machine tool type. Each usable command list 27 is information including a command and a description of the command for each of all commands that can be used by the machine tool of the target type, and is information for each type.

  FIG. 2 is a diagram illustrating an example of the usable command list 27. In the usable command list 27 shown in FIG. 2, “G0”, “G1”, “G2”, “G3”, “G2.3”, “G2.4”, “G0”, “G1”, “G3”, “G2.4”, G codes such as “G3.3”, “G3.4”, “G4”, and “G5” are included.

  In the usable command list 27, “G0” is “positioning”, “G1” is “linear interpolation”, “G2” is “circular interpolation CW”, “G3” is “circular interpolation CCW”, etc. As described above, an explanatory text indicating the content of the command is associated with each command.

  Returning to FIG. 1, the description of the storage unit 2 will be continued. The modal command-command use availability correspondence table 24 stored in the storage unit 2 is information that associates a usable command after each valid modal command for each modal command.

  FIG. 3 is a diagram illustrating an example of the modal command-command availability correspondence table 24. In the modal command-command availability correspondence table 24, “1” is associated with a usable command, and “0” is associated with a command that is not usable.

  In the example illustrated in FIG. 3, for “G68”, which is a modal command, “1” is associated with “G0”, “G1”, “G2”, “G3”, “G4”, and “G5”. .3 ”,“ G2.4 ”,“ G3.3 ”, and“ G3.4 ”are associated with“ 0 ”.

  Therefore, in the example shown in FIG. 3, when the effective modal command is “G68”, after “G68”, “G0”, “G1”, “G2”, “G3”, “G4”, and “G5” "Can be used, but" G2.3 "," G2.4 "," G3.3 ", and" G3.4 "are not allowed.

  Returning to FIG. 1, the description of the storage unit 2 will be continued. The block-by-block modal information 25 stored in the storage unit 2 is information including an effective modal command for each block. FIG. 4 is a diagram illustrating an example of the modal information 25 for each block.

  The block modal information 25 shown in FIG. 4 includes information indicating the effective modal of each group for each block number. In the example shown in FIG. 4, the effective modal command of the group “01” is “G0” in the block of the block number “1”, and “G1” in the block of the block number “N”. The block with the block number “1” indicates the first block of the machining program 21.

  The effective modal command of the group “13” is “G61.1” for the block with the block number “1” and “G61.1” for the block with the block number “N”. In FIG. 4, “N” is an integer of 2 or more, and “L” is an integer of 14 or more.

  Returning to FIG. 1, the description of the storage unit 2 will be continued. The command position information 26 for each block stored in the storage unit 2 is information including the command position for each block. FIG. 5 is a diagram illustrating an example of the command position information 26 for each block.

  In the block-by-block command position information 26 shown in FIG. 5, the command positions of the motors X, Y, Z, A, and C in the block with the block number “1” are “0.”, “0.”, “0”. .. ”,“ 0. ”, and“ 0. ”are included. Further, in the block-by-block command position information 26, “715.”, “505.”, “−300.”, “Command Position” of the motors X, Y, Z, A, and C in the block of the block number “N” are used. Information indicating “0.” and “0.” is included. The command positions of the motors X, Y, Z, A, and C are the command positions of the X axis, Y axis, Z axis, A axis, and C axis, respectively.

  Returning to FIG. 1, the description of the processing unit 3 will be continued. The processing unit 3 includes a machining program editing unit 30 that is an example of an editing unit, and a machining program analysis unit 40 that is an example of an analysis unit. The machining program editing unit 30 reads the machining program 21 from the storage unit 2 and displays the read machining program 21 on the display unit 5 based on the operator's input operation to the input unit 4. Further, the machining program editing unit 30 edits the machining program 21 displayed on the display unit 5 based on an input operation to the input unit 4 by the operator.

  The machining program analysis unit 40 analyzes a modal command effective for each block from the first block among the plurality of blocks constituting the machining program 21. The machining program analysis unit 40 generates modal information including information on effective modal instructions for each analyzed block, generates block-by-block modal information 25 including modal information for each generated block, and stores the generated modal information in the storage unit 2. .

  The machining program editing unit 30 moves a cursor displayed on the display unit 5 and indicating the current editing position based on an input operation to the input unit 4 by the operator. Based on the modal information stored in the storage unit 2, the machining program editing unit 30 determines a valid modal command in the block at the cursor position displayed on the display unit 5. The “cursor position displayed on the display unit 5” is the position of the cursor displayed on the display unit 5, and may be referred to as the cursor position or the cursor position below.

  The machining program editing unit 30 generates a usable command list that is a list of modal commands that can be used in the block at the cursor position, based on the modal commands effective in the block at the cursor position. The machining program editing unit 30 displays the generated usable command list on the display unit 5.

  Here, it is assumed that the operator gives an instruction to input a character string including at least some characters of the command at the cursor position by an input operation to the input unit 4. In this case, the machining program editing unit 30 extracts a modal command including a character string input from a plurality of modal commands included in the usable command list, thereby obtaining a modal command usable in the block at the cursor position. Generate a new usable command list that has been narrowed down. Then, the machining program editing unit 30 displays the generated new usable instruction list on the display unit 5.

  Thereafter, when the operator gives an instruction to input a further character by an input operation to the input unit 4, the machining program editing unit 30 extracts a modal command including a subsequent character in addition to the input character. A new usable command list in which usable modal commands are narrowed down is generated and displayed on the display unit 5.

  In this way, the machining program editing unit 30 generates and displays a usable command list in which usable modal commands are narrowed down every time the operator gives an input operation to the input unit 4 to input characters. This is displayed on part 5. As a result, the operator can confirm whether or not the command to be input can be used, and can edit the machining program 21 efficiently by preventing editing mistakes.

  In addition to the usable commands, the machining program editing unit 30 can generate a usable command list including a description of usable commands and display the usable command list on the display unit 5. Thus, the operator can check the explanation of the usable command in addition to whether or not the command to be input can be used, so that the machining program 21 can be edited more efficiently. it can.

  In addition, the machining program editing unit 30 warns that the input command cannot be used when the command including the input character string is not included in the available command list by the input operation to the input unit 4 by the operator. Is displayed on the display unit 5. Thereby, it is possible to prevent the operator from inputting an unusable command. Further, after the editing work of the machining program 21 is completed, it is necessary to confirm whether the machining program 21 has a correct command described using a machining program check device (not shown) mounted on the numerical control device of the machine tool. In addition, the operator can notice editing mistakes in the machining program 21 before checking using the machining program check device, so that the machining program 21 can be efficiently edited.

  Hereinafter, the machining program editing unit 30 and the machining program analysis unit 40 will be described in more detail. As shown in FIG. 1, the machining program editing unit 30 includes an input processing unit 31, a display processing unit 32, a cursor position determination unit 33, an effective modal extraction unit 34, and a command candidate generation unit 35. In addition, the machining program analysis unit 40 includes a read processing unit 41, a modal processing unit 42, and a coordinate processing unit 43.

  Hereinafter, processing of the processing unit 3 including the processing program editing unit 30 and the processing program analysis unit 40 will be described with reference to flowcharts. FIG. 6 is a flowchart illustrating an example of processing of the processing unit 3 of the machining program editing apparatus 1 according to the first embodiment. This processing is repeatedly executed by the processing unit 3.

  As illustrated in FIG. 6, the input processing unit 31 of the machining program editing unit 30 determines whether there is an editing start instruction for the machining program 21 (step S <b> 10). Such an editing start instruction is performed by an input operation to the input unit 4 by an operator.

  When it is determined by the machining program editing unit 30 that there is an instruction to start editing the machining program 21 (step S10: Yes), the machining program editing unit 30 executes an editing start process in accordance with an input operation to the input unit 4 ( Step S11). The process of step S11 is the process of steps S20 to S22 shown in FIG. 7, and will be described in detail later.

  The machining program editing unit 30 determines whether or not an editing position is designated when the process of step S11 is completed or when it is determined that there is no editing start instruction of the machining program 21 (step S10: No) ( Step S12). The designation of the editing position means that the position of the cursor displayed in the display area of the machining program 21 on the display unit 5 is designated. The edit position is designated by an input operation to the input unit 4 by the operator.

  When it is determined that the editing position is designated (step S12: Yes), the machining program editing unit 30 executes an available command list creation process (step S13). The usable command list creation process is a process of steps S41 to S45 shown in FIG. 10, and will be described in detail later.

  When the process of step S13 is completed or when it is determined that the edit position is not designated (step S12: No), the machining program editing unit 30 determines whether there is a character input (step S14). In the process of step S14, the machining program editing unit 30 determines that there is a character input when there is an instruction to input a character at the cursor position. The instruction to input characters is performed by an input operation to the input unit 4 by the operator.

  When it is determined that there is a character input (step S14: Yes), the machining program editing unit 30 executes an input support process (step S15). Such input support processing is processing in steps S50 to S56 shown in FIG. 12, and will be described in detail later.

  When the process of step S15 is completed or when it is determined that there is no character input (step S14: No), the processing unit 3 ends the process shown in FIG.

  FIG. 7 is a flowchart showing the editing start process in step S11 shown in FIG. As shown in FIG. 7, the machining program editing unit 30 reads the machining program 21 from the storage unit 2 (step S20). The display processing unit 32 of the machining program editing unit 30 displays at least a part of the plurality of blocks constituting the machining program 21 read in step S20 on the display unit 5 (step S21).

  Next, the machining program analysis unit 40 of the processing unit 3 performs an analysis process of the machining program 21 stored in the storage unit 2 (step S22). In the process shown in FIG. 7, the process of step S22 is performed after the process of step S21. However, the processing unit 3 can perform the process of step S21 and the process of step S22 in parallel. The process of step S21 can also be performed after the process of step S22.

  FIG. 8 is a flowchart showing the analysis processing in step S22 shown in FIG. As shown in FIG. 8, the read processing unit 41 of the machining program analysis unit 40 reads the first block from the machining program 21 stored in the storage unit 2 (step S30).

  Next, the modal processing unit 42 of the machining program analysis unit 40 extracts a modal command effective in the first block read out in step S30 (step S31). In step S31, the modal processing unit 42 extracts a modal command effective in the first block for each group based on the information included in the machine tool parameter 22 and the information on the first block.

  FIG. 9 is a diagram showing an initial state of modal commands for each group and effective modal commands for each block. In FIG. 9, the arrow indicates that a modal command is not included in the block.

  In the example shown in FIG. 9, the modal command in the initial state is “G0” in the group “01”, “G17” in the group “02”, “G61.1” in the group “13”, and the block number “1”. ”Blocks do not include modal commands for groups“ 01 ”,“ 02 ”, and“ 13 ”.

  Therefore, when the machining program 21 is in the state shown in FIG. 9, the modal processing unit 42 uses “G0” for the group “01” and “G17 for the group“ 02 ”as valid modal commands for each group in the first block. "And group" 13 "," G61.1 "is extracted. The machine tool parameter 22 includes a parameter that defines the initial state of the modal command. The initial state of the modal command of each group is determined based on the parameter that defines the initial state of the modal command. 42.

  Returning to FIG. 8, the description of the processing of the machining program analysis unit 40 will be continued. After the process of step S31, the modal processing unit 42 stores modal information in which the valid modal command extracted in step S31 is associated with the block number “1” of the “first block” in the storage unit 2 (step S32). ). Thereby, block-by-block modal information 25 including modal information of the first block is generated.

  Next, the coordinate processing unit 43 of the machining program analysis unit 40 calculates command positions of the motors X, Y, Z, A, and C mounted on a machine tool (not shown) (step S33).

  In step S33, the coordinate processing unit 43 instructs the motors X, Y, Z, A, and C in the first block based on the coordinate position specified by the movement command included in the first block of the machining program 21. Calculate the position. When the movement command included in the first block is an absolute value command, the coordinate commanded by the absolute value command is the command position. When the movement command is not included in the first block, the coordinate processing unit 43 sets the initial values of the motors X, Y, Z, A, and C included in the machine tool parameter 22 as the motors X, Y, Z, and C, respectively. The command positions of A and C can be used.

  The machining program analysis unit 40 stores, in the storage unit 2, command position information that associates the command position in the first block calculated in step S33 with the block number “1” of the “first block” (step S34). . Thereby, the command position information 26 for each block including the command position information indicating the command position of the head block is generated.

  Next, the machining program analysis unit 40 reads the next block from the machining program 21 stored in the storage unit 2 (step S35). When the previously read block is the first block, the “next block” is the block with the block number “2”, and when the previously read block is the block with the block number “N−1”, the “next block” “Block” is a block having a block number “N”.

  The modal processing unit 42 of the machining program analysis unit 40 extracts a modal command effective in the “next block” read in step S35, similarly to the processing in step S31 (step S36). In step S <b> 36, the modal processing unit 42 extracts a modal command effective for the “next block” for each group.

  When the “next block” is a block with the block number “N” and the state up to the block with the block number “N” is the state shown in FIG. 9, the group “ The modal commands “01”, “02”, and “13” are not included.

  Therefore, the modal information of the block number “N−1” stored in the storage unit 2 includes modal commands effective in the groups “01”, “02”, and “13”, respectively “G0”, “G17”. , And information indicating “G61.1”.

  The modal processing unit 42 acquires, from the block-by-block modal information 25, information indicating a modal command effective in each group stored in association with the block having the block number “N−1” stored in the storage unit 2.

  In the block with the block number “N”, as shown in FIG. 9, “G1” is included as a modal command of the group “01”. Therefore, the modal processing unit 42 extracts “G1” in the group “01” as a valid modal command in the block with the block number “N”. Further, since the block with the block number “N” does not include the modal commands of the groups “02” and “13”, the modal processing unit 42 performs “G17” and “13” in the group “02”. Then, “G61.1” is extracted.

  The modal processing unit 42 stores, in the storage unit 2, modal information that associates the modal command effective in the “next block” extracted in step S36 with the block number of “next block” (step S37). As a result, the modal information of “next block” is added to the modal information 25 for each block, and the modal information 25 for each block including the modal information of each block from the first block to the “next block” is generated. Information 25 is updated.

  Further, the coordinate processing unit 43 of the machining program analysis unit 40 calculates the command positions of the motors X, Y, Z, A, and C in the “next block” read in step S35 (step S38). .

  In step S38, the coordinate processing unit 43 calculates the command position in the “next block” based on the coordinate position specified by the movement command included in the “next block” read in step S35. When the movement command included in the “next block” is an absolute value command, the coordinate position specified by the absolute value command is set as the command position.

  In addition, when the movement command included in the “next block” is an incremental value command, the coordinate processing unit 43 adds the coordinate position specified by the incremental value command to the command position in the previous block. The command position in the “next block” is calculated.

  Then, the machining program analysis unit 40 stores the command position information in which the command position in the “next block” calculated in step S38 and the block number of the “next block” are associated with each other in the storage unit 2 (step S39). ). As a result, the command position information of the “next block” is added to the command position information 26 for each block, and the command position information 26 for each block including the command position information of each block from the first block to the “next block” is generated. Then, the command position information 26 for each block is updated.

  Next, the machining program analysis unit 40 determines whether or not all the blocks have been analyzed, that is, whether or not analysis of all of the plurality of blocks constituting the machining program 21 has been completed (step S40). If the machining program analysis unit 40 determines that all the blocks have not been analyzed (step S40: No), the process proceeds to step S35.

  Moreover, when it determines with the process program analysis part 40 having analyzed all the blocks (step S40: Yes), the process shown in FIG. 8 is complete | finished. 8 generates the block-by-block modal information 25 as shown in FIG. 4 and the block-by-block command position information 26 as shown in FIG.

  FIG. 10 is a flowchart showing the usable command list creation process in step S13 shown in FIG. As shown in FIG. 10, the cursor position determination unit 33 of the machining program editing unit 30 determines a block at the cursor position that is the position of the cursor 70 (step S41).

  The effective modal extraction unit 34 of the machining program editing unit 30 sends an effective modal command for each group in the block determined to have the cursor by the cursor position determination unit 33 from the block-by-block modal information 25 stored in the storage unit 2. Extract (step S42).

  Here, the block-by-block modal information 25 is in the state shown in FIG. 4, and the block-by-block modal information 25 includes modal information up to the block number “N”, and the cursor position is the block number “N”. Suppose that it is a block.

  In this case, the valid modal extraction unit 34 extracts the modal information of the block number “N” from the block-by-block modal information 25 as an effective modal command. That is, the effective modal extraction unit 34 determines, from the block-by-block modal information 25, “G1” for the group “01”, “G17” for the group “02”, “G61. 1 ”is extracted. Similarly, the effective modal extraction unit 34 extracts an effective modal command from the block-by-block modal information 25 for the groups “02” to “12”.

  As described above, the valid modal extraction unit 34 can extract the modal command of each group included in the modal information in the block number of the block at the cursor position from the block-by-block modal information 25 as an effective modal command.

  The effective modal extraction unit 34 can also extract from each block modal information 25 the modal commands effective for each group up to the cursor position. When the position of the cursor is at the head of the block having the block number “N + 1”, the modal command effective up to the cursor position is the same as the modal command effective in the block having the block number “N”. In this case, the effective modal extraction unit 34 can extract the modal information of the block number “N” from the block-by-block modal information 25 as an effective modal command.

  In addition, it is assumed that the cursor position is not at the head of the block with the block number “N + 1”, the cursor is positioned after the modal command in the block with the block number “N + 1”, and the block number “N + 1” is included in the modal information 25 for each block. "Is included. In this case, the valid modal extraction unit 34 can extract the modal commands of each group that are valid up to the position of the cursor including the modal commands included in the block of the block number “N + 1” from the modal information 25 for each block.

  Here, among the modal commands of each group included in the modal information of the block number “N”, in the block of the block number “N + 1”, only “G2” of the group “01” is displayed as the modal command before the cursor position. Suppose it is included.

  In this case, the valid modal extraction unit 34 reads “G2”, which is a modal command of the group “01”, from the modal information of the block number “N + 1” as a valid modal command, and the other groups “02” to “13”. Extracts a valid modal command from the modal information of the block number “N”.

  As described above, the effective modal extraction unit 34 obtains an effective modal command for each group in the block determined to have the cursor position by the cursor position determination unit 33 from the block-by-block modal information 25 stored in the storage unit 2. Can be extracted.

  Next, the command candidate generating unit 35 of the machining program editing unit 30 reads the modal command-command use availability correspondence table 24 from the storage unit 2 (step S43). Then, the command candidate generating unit 35 determines the cursor position based on the effective modal command for each group in the block at the cursor position extracted in step S42 and the modal command-command availability correspondence table 24 read in step S43. Commands usable in the block are extracted (step S44).

  Here, it is assumed that the modal command-command use availability correspondence table 24 is in the state shown in FIG. 3 and includes “G68” as a valid modal in the block at the cursor position. In the modal command-command availability table 24, the commands in which “0” is associated with “G68” are “G2.3”, “G2.4”, “G3.3”, and “G3.4”. It is not a usable command in the block at the cursor position.

  Therefore, the command candidate generation unit 35 excludes “G2.3”, “G2.4”, “G3.3”, and “G3.4” from the commands extracted as usable commands. Similarly, the command candidate generating unit 35 is a command in which “0” is associated with a modal command other than “G68” in the modal command-command availability correspondence table 24 among the modal commands effective in the block at the cursor position. Are excluded from the commands to be extracted as usable commands.

  In addition, the command candidate generation unit 35 extracts the description of the usable command extracted in step S44 from the usable command list 27, and the usable command including the usable command and the description extracted in step S44. A list is generated (step S45). When the processing program editing unit 30 ends the process of step S45, the processing shown in FIG. 10 ends.

  In the process of step S <b> 45, the command candidate generation unit 35 reads a parameter indicating the type of machine tool included in the machine tool parameter 22 stored in the storage unit 2. The command candidate generation unit 35 reads the usable command list 27 of the type set by the parameter from the usable command list 23 stored in the storage unit 2 based on the read parameter indicating the type of machine tool.

  Then, the command candidate generation unit 35 extracts the description of the usable command extracted in step S44 from the read usable command list 27. The command candidate generation unit 35 generates a usable command list in which the usable commands extracted in step S44 are associated with the explanatory text. The description of the command may be partially different depending on the type of the machine tool. Even in such a case, an appropriate usable command list corresponding to the set type of the machine tool can be generated.

  FIG. 11 is a diagram showing an example of the usable command list generated in step S45, which is a usable command list in the case where “G68” is included in the modal commands effective in the block determined to have the cursor position. is there. As described above, when “G68” is included in an effective modal command, “G2.3”, “G2.4”, “G3.3”, and “G3.4” cannot be used.

  Therefore, the usable command list 51 shown in FIG. 11 includes “G0”, “G1”, “G2”, “G3”, “G4”, and “G5” as usable commands. 3 ”,“ G2.4 ”,“ G3.3 ”, and“ G3.4 ”are not included.

  Further, in the usable command list 51, description of usable modal commands is associated with usable modal commands. For example, in the usable command list 51 shown in FIG. 11, “positioning” is associated with “G0” as the explanation of “G0”, and “linear interpolation” is associated with “G1” as the explanation of “G1”. Yes.

  FIG. 12 is a flowchart showing the input support processing in step S15 shown in FIG. As shown in FIG. 12, the input processing unit 31 of the machining program editing unit 30 adds the character determined to have been input in step S14 of FIG. 6 to the machining program 21 displayed on the display unit 5 (step S50).

  Next, the input processing unit 31 determines whether or not the input character that is the character determined to have been input in step S14 includes the command character (step S51). If the command candidate generation unit 35 of the machining program editing unit 30 determines that the input character includes the command character (step S51: Yes), it is necessary to update the list, that is, to update the usable command list 51. Is determined (step S52).

  In step S52, the command candidate generation unit 35 updates the usable command list 51 when the previously input character is included in the command character and a character subsequent to the previously input character is input. Is determined. For example, the command candidate generation unit 35 determines that the available command list 51 is to be updated when the previously input character is “G” and the subsequent character is a numerical value.

  When it is determined that the usable command list 51 needs to be updated (step S52: Yes), the command candidate generation unit 35 updates the usable command list 51 (step S53). In step S <b> 53, the command candidate generation unit 35 extracts a modal command including a character string including a character further following the previously input character from the usable command list 51, and generates a new usable command list 51. Thus, the usable command list 51 is updated.

  When the display processing unit 32 determines that the usable command list 51 is not required to be updated (step S52: No), or when the process of step S53 is completed, whether the usable command list 51 is empty or not. Is determined (step S54). The display processing unit 32 determines that the usable instruction list 51 is empty when one usable instruction is not included in the usable instruction list 51.

  When it is determined that the usable command list 51 is not empty (step S54: No), the display processing unit 32 displays the usable command list 51 on the display unit 5 (step S56). If the display processing unit 32 determines that the usable command list 51 is empty (step S54: Yes), the display processing unit 32 displays a warning on the display unit 5 (step S55). In step S <b> 55, the display processing unit 32 displays warning information on the display unit 5 by displaying warning information indicating that there is no usable command.

  In step S56, when the display processing unit 32 determines that the usable command list 51 needs to be updated (step S52: Yes), the display unit 5 displays the usable command list 51 updated in step S53 on the display unit 5. If the display processing unit 32 determines that the usable command list 51 does not need to be updated (No at Step S52), the display processing unit 32 displays the usable command list 51 that has not been updated at Step S53 on the display unit 5.

  When it is determined that the command character is not included in the input character (step S51: No), the machining program editing unit 30 is performed when the process of step S55 is completed or when the process of step S56 is terminated. The process shown in FIG.

  FIG. 13 is a diagram showing a transition example of the display screen displayed on the display unit 5 by the display processing unit 32, and shows how the display screen changes in accordance with the character input by the operator. The display screen 60a shown in FIG. 13 includes a machining program display area 61. In the machining program display area 61, at least a part of a plurality of blocks constituting the machining program 21 and the cursor 70 are displayed.

  In the machining program display area 61 of the display screen 60a, the block where the cursor 70 is located is at the beginning of the line one step below the last block in which the character is described, and the block where the cursor 70 is located contains a character. It is not described. In this case, the modal command effective in the block including the cursor 70 is the same as the modal command effective in the last block. Therefore, the command candidate generator 35 generates the usable command list 51 based on the modal information of the final block.

  In the state of the display screen 60 a shown in FIG. 13, it is assumed that the operator inputs a character “G” by an input operation to the input unit 4. It is assumed that the modal command-command availability correspondence table 24 is in the state shown in FIG.

  In this case, the display processing unit 32 of the machining program editing unit 30 adds the letter “G” to the position of the cursor 70 in the machining program display area 61 and the cursor 70 as shown in the display screen 60b of FIG. Move the position of to the right by one character. Since the character “G” is the first character of the command, the display processing unit 32 adds the list display area 62 to the display screen 60 b and displays the usable command list 51 generated by the command candidate generating unit 35. Displayed in the list display area 62.

  As shown in the machining program display area 61 of the display screen 60b, the block immediately before the block where the cursor 70 is located includes “G68” as a modal command. "G68" is included. Since the modal command-command availability correspondence table 24 is in the state shown in FIG. 3, the list display area 62 includes “G2.3”, “G2.4”, “G3.3”, and “G3.4”. Is not included.

  As a result, the operator can confirm whether or not the command to be input can be used, and can edit the machining program 21 efficiently by preventing editing mistakes. In addition, since the explanation text of the usable commands is displayed in the list display area 62, the usable commands can be easily grasped by the explanation text, and further, editing mistakes can be prevented and the machining program 21 can be efficiently edited. Work can be done.

  In the state of the display screen 60 b shown in FIG. 13, when the operator inputs a character “3” following a character “G” by an input operation to the input unit 4, the display processing unit 32 of the machining program editing unit 30 is displayed. As shown in the display screen 60c, in the machining program display area 61, the character “3” is added to the position of the cursor 70 and the position of the cursor 70 is moved to the right by one character.

  Further, the command candidate generating unit 35 of the machining program editing unit 30 extracts a command including the character example “G3” from the state shown in FIG. 11 from the usable command list 51 and generates a new usable command list 51. The available command list 51 is updated. The display processing unit 32 displays the updated usable command list 51 in the list display area 62 as shown in the display screen 60c of FIG.

  In this way, each time the operator inputs characters, a new usable command list 51 narrowing down usable commands is displayed on the display unit 5. Therefore, every time the operator inputs a character, the operator can check the usable command list 51 in which the character to be input next is displayed on the display unit 5, thereby preventing editing errors and efficiently editing the machining program 21. It can be performed.

  In addition, by selecting a command that the operator intends to input from the available command list 51 displayed on the display unit 5, the command input can be completed without the operator inputting characters. Specifically, the input processing unit 31 is a machining program 21 in which a command selected by the operator through an input operation to the input unit 4 from one or more commands included in the usable command list 51 is displayed on the display unit 5. Can be added to. In this case, the operator does not input an unusable command, and can edit the machining program 21 efficiently by preventing editing mistakes.

  In the above-described example, the processing unit 3 displays the usable command list 51 in which usable commands are narrowed down on the display unit 5, but can indicate to the operator that usable commands are narrowed down. Well, it is not limited to the example described above.

  For example, the command candidate generation unit 35 can also generate a command list so that a command including an input character can be visually distinguished from a command other than a command including the input character. In this case, the display processing unit 32 displays on the display unit 5 a command list that makes it possible to visually distinguish commands including input characters from commands other than commands including input characters. The command can be distinguished by highlighting the command including the input character by changing the size, color, and typeface of the command including the input character.

  In the above-described example, when the operator gives an instruction to input the character “G” that is the first character of the command by an input operation to the input unit 4, the usable command list 51 is displayed in the list display area 62. However, the display start timing of the usable command list 51 is not limited to the case where the first character of the command is input. When the operator designates the position of the cursor 70 by an input operation to the input unit 4, the display processing unit 32 displays a usable command list 51 including commands usable in the block at the cursor position in the list display area 62. You can also

  When the operator continuously inputs the characters “.” And “3” by the input operation to the input unit 4 from the state of the display screen 60c illustrated in FIG. 13, the characters following “G3” are “.3”. And the character string “G3.3” is entered. The command candidate generating unit 35 generates the usable command list 51 excluding commands other than the command including the character string “G3.3”. The usable command list 51 illustrated in FIG. 11 includes the character string “G3.3”. Is not included, the generated usable instruction list 51 is empty.

  When the usable command list 51 is empty, that is, when one usable modal command is not included in the usable command list 51, the display processing unit 32 determines that an unusable command is input, and the display unit 5 A warning is displayed.

  FIG. 14 is a diagram illustrating an example of a display screen when one or more subsequent characters “.3” are input from the state of the display screen 60 c illustrated in FIG. 13. In the list display area 62 of the display screen 60d shown in FIG. 14, the input explanation of “G3.3” and a message indicating that “G3.3” cannot be used are displayed.

  Accordingly, the operator grasps that the input command is a command that cannot be used, and changes the input command, so that the editing of the machining program 21 is completed while the command that cannot be used is set in the machining program 21. Can be prevented. In addition, since an explanatory note of the unusable command is displayed, the operator can easily grasp what the unusable command is.

  Further, the display screen 60d of FIG. 14 includes a warning display area 63. In the warning display area 63, a character string “P921 3D coordinate conversion invalid G code” is displayed. The character string displayed in the warning display area 63 is information indicating that an unusable command is performed in a state where “G68” which is a modal command is valid. Thereby, the operator can easily grasp why the input command cannot be used.

  When the character string “G3.3” is deleted from the character string “G3.3” by the input operation to the input unit 4, the display processing unit 32 displays the screen displayed on the display unit 5 from the display screen 60 d to the display screen. Change to 60c. Therefore, the warning display and warning display area 63 in the list display area 62 are canceled.

  In the above-described example, when the input command is a command that cannot be used, the operator displays a command that cannot be used. However, the machining program editing unit 30 indicates that the input command is a command that cannot be used. The entered command can be canceled.

  For example, when the character string “G3.3” is input from the state of the display screen 60 c illustrated in FIG. 13, the display processing unit 32 determines that the character string “G3.3” is not included in the usable command list 51. Then, “.3” of the character string “G3.3” can be canceled. As a result, the operator cannot substantially set a character string that is not included in the usable command list 51 in the machining program 21, thereby preventing the machining program 21 from including an unusable command. it can.

  Further, the machining program editing unit 30 may be configured so that an unusable command cannot be input. Specifically, the input processing unit 31 of the machining program editing unit 30 receives a character string when a character string that is a command character string and is not included in the usable command list 51 is input via the input unit 4. It is also possible not to accept input.

  For example, when the character string “.3” is input after the character string “G3” from the state of the display screen 60 c illustrated in FIG. 13, the input processing unit 31 performs the character string “.3” following the character string “G3”. "Is not included in the usable command list 51, and the input of the character" .3 "can not be accepted.

  Further, when the input command is an unusable command, the input processing unit 31 can not accept subsequent input by the operator until the unusable command input by the operator is canceled.

  In the list display area 62 described above, the commands included in the usable command list 51 are arranged in numerical order such as “G0”, “G1”, and “G2”, but are displayed in the list display region 62. Commands do not have to be in numerical order.

  For example, the machining program editing unit 30 can generate an available command list 51 in which commands are arranged in order of frequency of use, and the list display area 62 is an available command generated by the machining program editing unit 30. Based on the list 51, the commands arranged in the descending order of frequency of use can be displayed in the list display area 62.

  In this case, the machining program editing unit 30 stores a history of commands input by the operator through an input operation on the input unit 4 in the storage unit 2, and based on the command history stored in the storage unit 2, The frequency of use can be determined.

  In the above-described processing, the machining program analysis unit 40 generates the block-by-block modal information 25 when an instruction to start editing is given, but the present invention is not limited to this example. The machining program analysis unit 40 determines a modal command effective in the block including the input character by the same process as the process of step S36 every time the operator gives an instruction to input a character by an input operation to the input unit 4. be able to. The machining program analysis unit 40 updates the modal information 25 for each block when there is a valid modal command in the block including the input character.

  In addition, when the machining program analysis unit 40 determines that a command has been added to a block including an input character, the machining program analysis unit 40 stores modal information including a modal command effective in the block including the input character in the storage unit 2, for each block. The command position information 26 can also be updated.

  Similarly, each time the operator gives an instruction to input a character by an input operation to the input unit 4, the machining program analysis unit 40 performs a movement command included in the block including the input character by a process similar to the process of step S <b> 38. When there is, the command position can be calculated. The machining program analysis unit 40 updates the command position information 26 for each block when the command position is calculated.

  In addition, when it is determined that a movement command specifying coordinates is added to a block including an input character, the machining program analysis unit 40 stores command position information including a command position in a block including the input character in the storage unit 2. It is also possible to store and update the command position information 26 for each block.

  The machining program analysis unit 40 can also generate block-by-block modal information 25 when the machining program editing apparatus 1 is activated. When the processing load of the machining program editing apparatus 1 is equal to or less than a threshold, the block-by-block modal information is generated. 25 can also be generated.

  FIG. 15 is a diagram illustrating an example of a hardware configuration of the machining program editing apparatus 1 according to the first embodiment. As illustrated in FIG. 15, the machining program editing apparatus 1 is a computer including a processor 101, a memory 102, an HDD 103, an interface circuit 104, and a display 105. The processor 101, the memory 102, the HDD 103, the interface circuit 104, and the display 105 can exchange data with each other via the bus 106. The storage unit 2 is realized by the memory 102 and the HDD 103, the input unit 4 is realized by the interface circuit 104, and the display unit 5 is realized by the display 105.

  The processor 101 executes the functions of the machining program editing unit 30 and the machining program analysis unit 40 by reading and executing the OS and the processing program stored in the HDD 103. The processor 101 receives an OS and a processing program from one or more storage media among a magnetic disk, a USB (Universal Serial Bus) memory, an optical disk, a compact disk, and a DVD (Digital Versatile Disc) via an interface (not shown). It can also be stored in the read HDD 103 and executed.

  As described above, the machining program editing apparatus 1 according to the first embodiment includes the display processing unit 32, the machining program analysis unit 40 that is an example of an analysis unit, the effective modal extraction unit 34 that is an example of an extraction unit, A command candidate generation unit 35. The display processing unit 32 displays at least a part of the plurality of blocks included in the machining program 21 on the display unit 5. The machining program analysis unit 40 analyzes the modal command effective for each block from the first block among the plurality of blocks, and stores the modal information including the modal command effective for each block in the storage unit 2. The effective modal extraction unit 34 extracts a modal command effective in the block at the cursor position displayed on the display unit 5 from the block-by-block modal information 25 stored in the storage unit 2. The command candidate generation unit 35 generates a usable command list 51 that is a list of modal commands that can be used in the block at the cursor position, based on the valid modal commands extracted by the valid modal extraction unit 34. When a character string is input at the position of the cursor 70, the command candidate generation unit 35 extracts a modal command including the input character string from a plurality of modal commands included in the usable command list 51, and newly creates a new command. A usable instruction list 51 is generated. The display processing unit 32 displays the usable command list 51 generated by the command candidate generating unit 35 on the display unit 5. Thereby, the operator can confirm whether the command to be input can be used, and can efficiently edit the machining program 21.

  The usable command list 51 includes usable commands and a description of the command. Thus, the operator can check the explanation of the usable command in addition to whether or not the command to be input can be used, so that the machining program 21 can be edited more efficiently. it can.

  In addition, when the input command is not included in any of the plurality of modal commands included in the available command list 51, the display processing unit 32 displays a warning indicating that the input command cannot be used on the display unit 5. indicate. As a result, it is possible to prevent the operator from inputting a command that cannot be used, and it is not necessary to check the machining program 21 with the machining program check device after the editing operation of the machining program 21 is completed. The program 21 can be edited.

Embodiment 2. FIG.
In the second embodiment, a process for displaying a warning when the command positions of the motors X, Y, Z, A, and C are outside the setting range in the cursor position block is added. And different. In the following, constituent elements having the same functions as those in the first embodiment are denoted by the same reference numerals, description thereof will be omitted, and differences from the machining program editing apparatus 1 in the first embodiment will be mainly described.

  FIG. 16 is a diagram showing a configuration of a machining program editing apparatus 1A according to the second embodiment of the present invention. A machining program editing apparatus 1A shown in FIG. 16 includes a storage unit 2A, a processing unit 3A, an input unit 4, and a display unit 5.

  The storage unit 2A stores machine tool parameters 22A instead of the machine tool parameters 22 in the storage unit 2. The machine tool parameter 22A includes, in addition to the parameters included in the machine tool parameter 22, a parameter representing a coordinate system to be used, a parameter indicating a movable range of each motor X, Y, Z, A, and C mounted on the machine tool, A parameter indicating the position of the interferer is included.

  FIG. 17 is a diagram illustrating an example of the movable range information table 71 including a parameter indicating the movable range. In the movable range information table 71 shown in FIG. 17, “−20.000”, “−20.000”, “−” are set as parameters indicating the lower limits of the movable ranges of the motors X, Y, Z, A, and C. “−1020.000”, “−190.000”, and “0.000” are set.

  Further, in the movable range information table 71 shown in FIG. 17, “820.000”, “820.000”, “ “20.000”, “190.000”, and “0.000” are set.

  Therefore, the movable range of the motor X is -20 mm to 820 mm, the movable range of the motor Y is -20 mm to 820 mm, the movable range of the motor Z is -1020 mm to 20 mm, and the movable range of the motor A is , -190 mm to 190 mm. For the motor C, the setting of the movable range is invalid.

  The interference object range information table including the parameter indicating the range of the interference object is stored in the storage unit 2A as a part of the machine tool parameter 22A, similarly to the movable range information table 71 shown in FIG. In the movable range information table 71, information indicating the movable range is included, but in the interfering object range information table, information indicating a range where there is an interfering object is included.

  Based on the movable range information table 71 and the interferer range information table, a set range Rm that is a range in which the movement of the motors X, Y, Z, A, and C is permitted is determined. The set range Rm is a range that is within the movable range defined by the movable range information table 71 and does not include a certain range of interferers defined by the interferer range information table.

  FIG. 18 is a diagram illustrating an example of the coordinate setting information table 73 including coordinate setting parameters. The coordinate setting information table 73 shown in FIG. 18 includes information indicating the origin coordinates of each command. In the example shown in FIG. 18, the origin in the coordinate system of the command “G54” is the positions of 0 mm, 0 mm, −1000 mm, 0 mm, and 0 mm on the X axis, Y axis, Z axis, A axis, and C axis, respectively. .

  In the example shown in FIG. 18, the origin in the coordinate system of the command “G55” is the positions where the X axis, Y axis, Z axis, A axis, and C axis are 500 mm, 500 mm, −800 mm, 0 mm, and 0 mm, respectively. It is. Hereinafter, the motors X, Y, Z, A, and C are collectively referred to as a motor M, the movable range of the motor M is a movable range Ra, and the position range of the interferer is an interferer range Rb.

  Returning to FIG. 16, the processing unit 3A will be described. As illustrated in FIG. 16, the processing unit 3A includes a machining program editing unit 30A and a machining program analysis unit 40. The machining program editing unit 30A includes an input processing unit 31, a display processing unit 32A, a cursor position determination unit 33, an effective modal extraction unit 34, a command candidate generation unit 35, and a command position determination unit 36.

  Based on the parameter indicating the movable range described above, the command position determination unit 36 determines whether or not the command position of each motor M in the block is outside the movable range Ra of each motor M based on the movement command included in the block at the cursor position. judge. Further, the command position determination unit 36 is based on the parameter indicating the range of the interferer described above, and the interferer range in which the command position of each motor M of the block causes a collision with the interferer due to the movement command included in the block at the cursor position. It is determined whether or not it is within Rb.

  When the display processing unit 32A includes a movement command for moving the motor M outside the movable range Ra or a movement command for moving within the interferer range Rb, the display processing unit 32A determines that the moving command for moving outside the set range Rm is included, and warns the display unit 5 Display information. Thereby, it is possible to prevent the operator from inputting a movement command of the motor M to the outside of the movable range Ra and a movement command to the inside of the interference object range Rb, and the effect of improving the efficiency of editing the machining program 21 can be obtained. .

  FIG. 19 is a flowchart showing an input support process executed by the machining program editing unit 30A. The processing in steps S50 to S56 shown in FIG. 19 is the same as the processing in steps S50 to S56 shown in FIG.

  When the process of step S55 or the process of step S56 is completed, the command position determination unit 36 of the machining program editing unit 30A includes the coordinate position specified by the movement command in the block at the cursor position by the input of the character. It is determined whether or not (step S61). The coordinate position specified by the movement command is a coordinate position described after the movement command. In the case of “G90 G0 X150.”, The coordinate position is “X150.”.

  When it is determined that the coordinate position specified by the movement command is included in the block at the cursor position (step S61: Yes), the command position determination unit 36 calculates the command position in the block at the cursor position (step S62). ).

  In step S62, the command position determination unit 36 extracts command position information of the block immediately before the block at the cursor position from the block-by-block command position information 26 stored in the storage unit 2A. Then, the command position determination unit 36 determines the command in the block at the cursor position based on the command position indicated by the extracted command position information and the coordinate position specified by the movement command that is included in the cursor position block. Determine the position.

  When the command position information 26 for each block is updated every time a character is input at the position of the cursor 70 by the machining program analysis unit 40, the command position determination unit 36 stores the command position for each block stored in the storage unit 2A. The command position information of the block at the cursor position is extracted from the information 26. The command position determination unit 36 determines the command position indicated by the command position information of the block at the cursor position as the command position in the block at the cursor position.

  Next, the command position determination unit 36 reads a parameter indicating the movable range included in the movable range information table 71 and a parameter indicating the range of the interferer included in the interferer range information table from the storage unit 2A (step S63).

  The command position determination unit 36 determines whether or not the command position calculated in step S62 is outside the set range Rm based on the parameter read in step S63 (step S64). When the command position determination unit 36 determines that the command position is outside the set range Rm (step S64: Yes), the display processing unit 32A displays warning information on the display unit 5 (step S65).

  When it is determined that the coordinate position of the movement command is not included in the block at the cursor position (step S61: No), the command position determination unit 36 determines that the command position is not outside the set range Rm (step S64: No). ), Or when the process of step S65 ends, the process shown in FIG. 19 ends.

  FIG. 20 is a diagram illustrating an example of the display screen 60 e of the display unit 5. The display screen 60e shown in FIG. 20 includes a warning display area 64 in addition to the machining program display area 61. In the example shown in FIG. 20, in the machining program 21, the command “G55” is included in the block immediately before the block at the cursor position, and the block immediately before the cursor position block and the block at the cursor position are included. An effective command is a command on the G55 coordinate system.

  The block immediately before the cursor position block includes a command “G90”, a command “G0”, and a coordinate position “X200”, and positioning is performed at 200 mm on the X axis by the absolute value command method. To command. When the coordinate setting information table 73 is in the state shown in FIG. 18, the G55 coordinate system has an X-axis origin of 500 mm. In this case, in the block immediately before the block at the cursor position, the motor X is instructed to move to a position of 700 mm.

  The block at the cursor position includes a command “G91”, a command “G1”, and a coordinate position “X150.”, And is commanded to perform cutting feed at 150 mm on the X axis by the incremental value command method. . Therefore, in the block at the cursor position, the motor X is instructed to move to a position of 850 mm.

  When the movable range information table is in the state shown in FIG. 17, the movable range of the motor X is −20 mm to 820 mm, 850 mm is out of the movable range, and the operator moves outside the set range Rm in the block at the cursor position. A movement command is input. Accordingly, as shown in FIG. 20, the display processing unit 32A displays a warning in the warning display area 64 of the display unit 5 indicating that a movement command for moving in the positive direction of the X axis beyond the set range Rm has been performed. .

  As described above, the machining program editing apparatus 1A according to the second embodiment displays a warning when the operator inputs a movement command to the outside of the setting range Rm of the motor M. Therefore, the operator sets the setting range Rm of the motor M. It is possible to prevent an outward movement command from being input. Therefore, confirmation by the machining program check device after completion of the editing operation of the machining program 21 can be eliminated, and an effect of improving the efficiency of the editing operation of the machining program 21 can be obtained.

  In addition to the above-described warning display, or instead of the above-described warning display, the machining program editing unit 30A has a case where the command position set by the coordinate position of the input movement command is outside the setting range Rm. The coordinate position of the input movement command can be canceled.

  Further, the machining program editing unit 30A may be configured not to input the coordinate position of the movement command outside the setting range Rm. Specifically, the input processing unit 31 of the machining program editing unit 30A inputs a character when a character string describing the coordinate position of the movement command outside the setting range Rm is input via the input unit 4. It can also be rejected.

  The hardware configuration example of the machining program editing apparatus 1A according to the second embodiment is the same as that of the machining program editing apparatus 1 shown in FIG. The processor 101 reads out and executes the program stored in the memory 102 functioning as the storage unit 2A, thereby executing the functions of the display processing unit 32A and the command position determination unit 36 in addition to the functions of the processing unit 3 described above. be able to.

The display processing unit 32 </ b> A displays at least a part of the plurality of blocks included in the machining program 21 on the display unit 5. The machining program analysis unit 40 analyzes the machining program 21 from the first block, and stores block-by-block command position information 26 including command position information indicating the command position of the motor M included in the machine tool for each block of the machining program 21. Store in part 2A. Based on the command position information 26 for each block stored in the storage unit 2A, the command position determination unit 36 sets the command position of the motor M to the set range Rm according to the movement command input to the position of the cursor 70 displayed on the display unit 5. Judge whether to go out. The display processing unit 32A warns that the command position of the motor M is out of the set range Rm when the command position determination unit 36 determines that the command position is out of the set range Rm according to the input movement command. Information is displayed on the display unit 5. As a result, it is possible to prevent the operator from inputting a command to move the motor M outside the set range Rm, and the machining program 21 can be efficiently edited.

The modal processing unit 42B stores the modal information for each block including the modal command and the modal type effective in each block as the modal information 25B for each block in the storage unit 2B.

  The display processing unit 32B reads the modal information of the block at the cursor position from the block-by-block modal information 25B stored in the storage unit 2B by the same processing as the display processing units 32 and 32A, and displays the read modal information on the display unit 5. indicate.

  The modal information displayed on the display unit 5 includes information indicating whether the modal command effective in the block at the cursor position is the modal command in the initial state or the modal command. Thus, the operator can easily recognize whether or not the command in the block at the editing position depends on the parameter setting.

  FIG. 23 is a flowchart showing the analysis processing in step S22 shown in FIG. The processes of steps S30, S31, S33 to S36, and S38 to S40 shown in FIG. 23 are the same as the processes of steps S30, S31, S33 to S36, and S38 to S40 shown in FIG.

  As shown in FIG. 23, the default modal determination unit 44 determines a modal type that is an effective modal type in the first block (step S71). In step S71, the default modal determining unit 44 determines a modal type indicating whether a modal command effective in each block is a modal in the initial state or a modal by the command.

  The modal processing unit 42B stores, in the storage unit 2B, modal information including the valid modal command extracted in step S31, information indicating the modal type, and the block number “1” of the “first block” (step S32B). Thereby, the block-by-block modal information 25B including the modal information of the head block is generated.

  In step S72, the default modal determination unit 44 determines the modal type of the modal command effective in the “next block” read in step S35, similarly to the process in step S71 (step S72).

  The modal processing unit 42B stores, in the storage unit 2B, modal information including the valid modal command extracted in step S36, information indicating the modal type, and the block number of “next block” (step S37B). As a result, the modal information of “next block” is added to the modal information 25B for each block, and the modal information 25B including the modal information for each block from the first block to the “next block” is generated. Information 25B is updated.

  FIG. 24 is a flowchart showing a modal information display process. As shown in FIG. 24, the cursor position determination unit 33 of the machining program editing unit 30B determines a block at the cursor position (step S81).

Therefore, the effective modal command of the group “01” in the block at the cursor position is “G1”. In the block at the cursor position, the effective modal command for group “03” is “G91”, and the effective modal command for group “12” is “G55”.

  In groups “02” and “13”, no command is given from the first block of the machining program 21 to the block at the cursor position. Therefore, the effective modal command of the group “02” is “G17” and the effective modal command of the group “13” is “G61.1” according to the parameters that define the initial state of the modal command.

  In the modal display area 65 shown in FIG. 25, the command “G17” and the command “G61.1” are highlighted to show that the modal is in the initial state. Thus, the operator can easily recognize whether or not the command in the block at the editing position depends on the parameter setting. In FIG. 25, the highlighting indicating that the modal is in the initial state is performed by surrounding the command with a frame. However, the command may be highlighted by changing the size, color, and typeface of the command. .

  In addition, the coordinate processing unit 43 can calculate the command position, the rotation speed, and the feed speed of each motor M for each block, and store the calculation result as the block-specific command position information 26 in the storage unit 2B.

The machining program analysis unit 40B analyzes an effective modal command for each block from the first block of the machining program 21, and determines a modal type that is a type of whether or not the effective modal command is an initial parameter. The machining program analysis unit 40B stores modal information indicating a modal command and a modal type effective for each block in the storage unit 2B. The effective modal extracting unit 34 extracts modal information indicating a modal command effective in the block at the cursor position displayed on the display unit 5 from the block-by-block modal information 25B stored in the storage unit 2B. Based on the modal information extracted by the effective modal extraction unit 34, the display processing unit 32B displays a modal command and a modal type that are effective in the block at the cursor position on the display unit 5. Thereby, the operator can easily recognize whether or not the modal command in the block at the editing position depends on the parameter setting, and can efficiently edit the machining program 21.

Embodiment 4 FIG.
The fourth embodiment is different from the first to third embodiments in that when the machining program is a subprogram, analysis is performed from the head block of the main program, not the head of the machining program. In the following, constituent elements having the same functions as those in the third embodiment are denoted by the same reference numerals, description thereof is omitted, and differences from the machining program editing apparatus 1B in the third embodiment are mainly described.

  FIG. 26 is a diagram showing a configuration of a machining program editing apparatus 1C according to the fourth embodiment of the present invention. A machining program editing apparatus 1C shown in FIG. 26 includes a storage unit 2C, a processing unit 3C, an input unit 4, and a display unit 5.

  The storage unit 2C stores a machining program group 28 including a plurality of machining programs. The machining program group 28 shown in FIG. 26 includes a main program 21A and a subprogram 21B as a plurality of machining programs. In FIG. 26, one main program 21A and one subprogram 21B are shown, but a plurality of main programs 21A and subprograms 21B are included in the machining program group 28, respectively.

  The main program 21A includes a command called a subprogram call command, and can be executed by calling the subprogram 21B from the main program 21A. Effective modal commands and command positions from the first block of the main program 21A to the subprogram call command are succeeded to the subprogram 21B.

  Since the subprogram call command specifies which subprogram 21B to call, the subprogram 21B can be known from the main program 21A, but the subprogram 21B includes a description of the main program 21A. Absent. Therefore, the main program 21A cannot be known from the subprogram 21B.

  Therefore, when the operator is editing the subprogram 21B, even if an effective modal command and command position are analyzed from the first block of the subprogram 21B, the effective modal command and command position may not be accurately analyzed. There is.

  Therefore, the processing unit 3C performs from the first block of the main program 21A, which is the processing program of the caller, to the last block from the first block of the subprogram 21B that is editing via the block including the subprogram call command. Is analyzed for each block.

  The processing unit 3C includes a machining program editing unit 30C, a machining program analysis unit 40B, and a main program search unit 50. The main program retrieval unit 50 retrieves the main program 21A, which is the machining program from which the subprogram 21B, which is the machining program that is editing, performs a full-text search from the machining program group 28 stored in the storage unit 2C. Extract.

  The machining program editing unit 30C requests the main program search unit 50 to find the main program 21A that calls the subprogram 21B being edited before the machining program analysis unit 40B performs program analysis. When the main program search unit 50 extracts the main program 21A, the machining program editing unit 30C instructs the machining program analysis unit 40B to perform analysis from the top block of the main program 21A.

  The machining program analysis unit 40B analyzes for each block from the first block of the main program 21A to the last block of the subprogram 21B that is being edited via the subprogram call command block.

  Specifically, the machining program analysis unit 40B analyzes the block from the head block of the main program 21A to the block including the subprogram call command for each block, similarly to the analysis process of the machining program 21 described above. Subsequently, the machining program analysis unit 40B analyzes, for each block, the first block to the last block of the subprogram 21B that is the destination of the subprogram call command of the main program 21A and is being edited.

  The machining program analysis unit 40B uses modal information of a block including a subprogram call command as modal information effective immediately before the top block of the subprogram 21B. Thereby, the subprogram 21B can be analyzed from the head block of the subprogram 21B by using the modal command effective in the block including the subprogram call command of the main program 21A as the modal command in the initial state.

  The machining program analysis unit 40B stores the analyzed modal information for each block in the storage unit 2C as modal information for each block 25B, and stores the analyzed command position information for each block in the storage unit 2C as the command position information for each block 26. .

  Note that the main program search unit 50 uses the idle time of the processor 101 to determine the main program 21A that is the calling source of each subprogram 21B even when there is no instruction from the machining program editing unit 30C. Can do. In this case, the main program search unit 50 can store information indicating the relationship between the determined subprogram 21B and the main program 21A in the storage unit 2C.

  As illustrated in FIG. 27, the machining program editing unit 30C determines whether or not the machining program displayed on the display unit 5 and being edited is the subprogram 21B (step S91). When the machining program editing unit 30C determines that the machining program being edited is the subprogram 21B (step S91: Yes), the machining program editing unit 30C instructs the machining program analysis unit 40B to analyze the main program 21A from which the subprogram 21B is read. The machining program analysis unit 40B executes analysis of the main program 21A (step S92). Such step S92 is the same as the processing of steps S30 to S40 shown in FIG.

  When the process of step S92 is completed, or when it is determined that the machining program being edited is not the subprogram 21B (step S91: No), the machining program editing unit 30C analyzes the machining program being edited. The analysis unit 40B is instructed, and the machining program analysis unit 40B executes analysis of the main program 21A (step S93).

  In step S94, when the machining program being edited is the subprogram 21B, the machining program editing unit 30C uses the block modal information including the subprogram call command in the main program 21A as the modal command in the initial state. The subprogram 21B is analyzed from the first block of 21B. Such step S93 is the same as the processing of steps S30 to S40 shown in FIG. When the process of step S93 ends, the processing unit 3C ends the process illustrated in FIG.

  FIG. 28 is a diagram showing an example of the display screen of the display unit 5, and FIG. 29 is a diagram showing an example of the main program 21A. The display screen 60g shown in FIG. 28 includes a machining program display area 61 and a modal display area 65, which are subprogram display areas. In the machining program display area 61 shown in FIG. 28, at least part of the contents of the subprogram 21B, which is the machining program being edited, is displayed.

  The display screen 60g shown in FIG. 28 shows that the command “G55” included in the main program 21A shown in FIG. 29 is an effective modal command of the group “12” in the block at the cursor position in the subprogram 21B. It is. In order to indicate that the command “G55” is a command in the main program 21A, not in the subprogram 21B being edited, it is displayed in italics in distinction from the modal commanded by the subprogram 21B being edited.

  As a result, even if the machining program being edited is the subprogram 21B, the operator can grasp the effective modal command in the block at the cursor position, which is the same as when the machining program check device confirms from the main program 21A. Program analysis.

  A hardware configuration example of the machining program editing apparatus 1C according to the fourth embodiment is the same as that of the machining program editing apparatus 1 shown in FIG. The processor 101 can execute the function of the processing unit 3C described above by reading and executing a program stored in the memory 102 functioning as the storage unit 2C.

  As described above, the machining program editing apparatus 1 </ b> C according to the fourth embodiment includes the main program search unit 50. The main program search unit 50 searches for the main program 21 </ b> A that is the calling source of the machining program 21. The machining program analysis unit 40B performs analysis from the first block of the main program 21A instead of the first block of the machining program that is the subprogram 21B. Thereby, even when the operator is editing the subprogram 21B, an effective modal command at the editing position can be accurately grasped, and the machining program 21 can be efficiently edited. .

  In the above-described example, the warning to the operator is performed by display on the display unit 5, but the machining program editing units 30, 30 </ b> A, 30 </ b> B, and 30 </ b> C are replaced with sound and vibration instead of display on the display unit 5.
