[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a numerical controller that displays tool data such as tool numbers used in a machining program, coordinate system data, and the like on a screen that also displays their correction data.

[0002]

[Prior art]

 The numerical control device consists of a machining program that consists of numerical control data such as coordinate values that indicate the path that the tool should move, the type of the tool, the tool feed speed, and the spindle rotation speed, and the tool that is used in the machining program. It operates according to the compensation amount and the compensation amount of the work mounting position. These correction amounts are measured for each tool or each work before starting machining and set in the correction amount memory.

Conventionally, for example, in a tool correction screen 50 as shown in FIG. 7, a tool list 52 used is displayed on the right side, and a tool correction screen showing a correction number and correction amounts 55 and 56 is displayed on the left side. Has been done. The used tool list 52, which is a list of tools used in the machining program, is created automatically by the numerical controller from the machining program by entering the machining program number and pressing the list creation key 51. is there. Then, the tool length correction number 53 and the tool diameter correction number 54 corresponding to each tool were visually confirmed from the tool list 52, and the page key or the cursor key was operated or confirmed according to the number. By inputting the correction numbers 53 and 54 and pressing the cursor key, the cursor 57 is moved to the display position of the corresponding correction amount 55 and 56 in the tool correction screen to set or confirm the correction amount. .

[0004]

[Problems to be solved by the device]

 However, the above method has a problem that the tool list 52 cannot be created unless the machining program number is input and the list creation key 51 is pressed, which is troublesome.

Further, when visually confirming the correction numbers 53 and 54 for each tool in the tool list 52 to be used, there is a possibility of misunderstanding. For example, in FIG. 7, the long correction number (6 ), Mistakenly look at the length correction number (7) of the end of T0007 one step lower, and confirm the numerical value (-24 3.486) that originally corresponds to the length correction number (6). However, there was a case in which an error of checking the numerical value of (-251.249) corresponding to the long correction number (7) was made. There was a risk that such an error would sometimes lead to a major accident.

Further, in the method of operating the page key and the cursor key to move the cursor 57 to the corresponding correction amounts 55 and 56, many key operations are required, which requires a great deal of time and labor, and In the method of inputting the correction numbers 53 and 54 and pressing the cursor key, there is a possibility that the correction numbers 53 and 54 may be erroneously input, resulting in the same serious accident as described above.

The present invention has been made in view of the above problems of the conventional numerical control device, and an object of the present invention is to provide a numerical control device that does not require a troublesome operation and can set an accurate correction amount. It is a thing.

Is a means for comparing the program creation time with the extraction time. When the tool compensation screen is newly displayed, the control means 33 does not operate the extraction means 31 newly if the extraction time is newer than the program creation time based on the comparison result of the comparison means 32. In this case, the extraction means 31 is a means for newly operating.

Further, a tool correction screen is displayed on the CRT 4a. Reference numeral 4b is a keyboard connected to the CRT 4a. Further, the correction amount storage means 7 stores a tool length correction amount, a tool radius correction amount, a work coordinate system correction amount, and the like. In addition, the correction amount search means 34 determines the specific correction amount corresponding to the specific data selected in the extracted data displayed on the tool correction screen from among the correction amounts displayed on the tool correction screen. It is a means for selecting and specifying from.

FIG. 2 is a block diagram when the present embodiment is realized by a computer. That is, the processor 2 controls the operation of the entire device according to the system program stored in the ROM 3, and the keyboard 4b with the CRT 4a transmits various data via the input / output unit (I / F) 5. It is a means of inputting. The CRT 4a is a means for displaying various data in accordance with the instruction of the processor 2, as described above. The machining program storage means 6 stores a machining program. As described above, the correction amount storage means 7 stores the tool length correction amount, the tool radius correction amount, the work coordinate system correction amount, and the like. The extracted data storage means 8 corresponds to the tool number and correction number data extracted by the extraction means 31 from the predetermined machining program and the tool number extracted from the tool file data storage means 9 as described above. This is the means by which the tool data is stored, and these data become the data of the tool list used. The correction amount search program 11 is a ROM that stores a program for realizing the correction amount search means 34. Reference numeral 12 is a program number storage means for storing the number of the machining program selected on the screen for executing machining, as described above. As mentioned above, 13 is a program creation time storage means for storing the creation time of the machining program. Reference numeral 14 is an extraction program number storage means for storing the number of the program whose data has been extracted by the extraction means 31, as described above. Reference numeral 15 is an extraction time storage means for storing the time when the data is extracted by the extraction means 31, as described above. Reference numeral 10 is a ROM that stores a program for realizing the extraction means 31.

Note that these constituent elements are connected to each other by a bus line 16.

Next, the operation of the above embodiment will be described with reference to the flowcharts of FIGS. 3 and 4 showing an example of the tool correction screen.

When the tool correction screen 20 is displayed on the CRT 4a, the comparison means 32 compares the contents of the program number storage means 12 and the extracted program number storage means 14 to create a machining program number and a tool list to be used. If the program numbers are different, the process proceeds to S3 (S1). If the program numbers are the same, the contents of the program creation time storage means 13 and the extraction time storage means 15 are further compared. If the extraction time is newer, the process proceeds to S4 ( S2). If not, the control means 33 drives the extraction means 31, and the extraction means 31 automatically calls the machining program of the number stored in the program number storage means 12 from the machining program storage means 6, The tool number, tool length correction number, and tool radius correction number are extracted from the program, and the tool name and tool diameter corresponding to the extracted tool number are extracted from the tool file data storage means 9, and these data are stored as extracted data. It is stored in the means 8. Then, the stored data is displayed as a used tool list in the used tool list 22 of the tool correction screen 20 (S3).

Next, when the cursor switching key 23 is pressed, the cursor switching key 23 is displayed in reverse as shown in FIG. 3, and the cursor 24 is also displayed in the used tool list 22 (S4). This cursor 24 is displayed on the entire line, and it is possible to confirm which of the long correction number and the diameter correction number is selected depending on the different color portion. The long correction number and the diameter correction number are selected by the cursor keys on the keyboard.

At this time, the correction amount search means 34 reads the correction number selected by the cursor 24 on the tool list side 28 (S 5), and the corresponding correction number among the correction numbers currently displayed on the correction amount side 27 is read. The cursor is moved to the correction amount portion in the correction number (S7). If there is no corresponding correction number on the correction amount side 27, the page on the correction amount side 27 is scrolled to display the page having the corresponding correction number (S6), and then the cursor 25 is moved to that position. It is automatically moved to the correction amount (S7). The cursor switch key 23 is a key for selecting which cursor to operate, the correction amount side 27 or the tool list side 28, and the cursor on the correction amount side 27 in the normal display and the tool list side 28 in the reverse display. Be the target of operation.

After the cursor 25 is moved, the update setting is made or the confirmation key 29 is used to confirm that the change is not made, and the correction amount is input, and the correction amount is edited (S8). In addition, the color of the correction number portion on the used tool list side 28 which has been set or confirmed in such a manner is changed so that it can be easily distinguished from an unconfirmed or unconfirmed one. It should be noted that the distinction may be made by inversion or blinking other than the color change.

If there is another correction number that is not set or has not been confirmed on the tool list side 28 to be used, the cursor 24 on the tool list side 28 is moved to the correction number (S10), and the above operation is performed. repeat.

If there is no unset or uncorrected correction number on the tool list side 28 to be used, when the cursor switch key 23 is pressed, the cursor switch key 23 returns to the normal display and the cursor 24 on the tool list side 28 disappears. (S11).

FIG. 5 is a diagram showing an example of the coordinate system correction screen 40 in the numerical control device to which the present invention is applied.

Also in this case, like the tool compensation screen 20, when the coordinate system compensation screen 40 is displayed, the machining program of the number stored in the program number storage means 12 is automatically called from the machining program storage means 6, and the program is called. The coordinate system is extracted from the list and is displayed in the used coordinate system list 42. When the cursor switching key 43 is pressed, the cursor 44 is also displayed on the used coordinate system list 42. At this time, the correction amount search means 34 reads the coordinate system selected by the cursor 44 on the used coordinate system list side and displays the correction amount side. The cursor 45 is automatically moved to the corresponding correction amount. For example, in this embodiment, the cursor 45 is moved to the X-axis correction amount of the corresponding coordinate system.

While the cursor switching key 43 is highlighted, the correction amount side cursor 45 also moves in accordance with the movement of the cursor 44 on the used coordinate system list side.

When the cursor switching key 43 is pressed again, the cursor switching key 43 returns to the normal display, and the cursor 44 on the used coordinate system list side disappears.

Next, as another embodiment, even if the cursor switching key 23 is pressed to display the cursor 24 on the tool list side used, or the cursor 24 on the tool list side is moved to another correction number, The cursor 25 on the correction amount side does not move, and when the search key 26 which is displayed only when the cursor switching key 23 as shown in FIG. 6 is highlighted, the cursor 24 on the tool list side to be used is selected at that time. It is also possible to read the correction number that is present, search the corresponding correction amount by the correction amount search means 34, and move the cursor 25 on the correction amount side. By doing so, the correction amount searching means 34 does not operate every time the cursor 24 on the used tool list side moves, so that there is an advantage that the moving processing speed of the cursor 24 can be increased.

As described above, according to the present embodiment, it is not necessary to perform the key operation for creating the tool list to be used, and when the predetermined screen is displayed, the machining program selected on the screen for always executing the machining is selected. The latest tool list of has been created.

Further, when the machining program selected on the screen for executing machining is the same as the machining program which has created the currently used tool list and the creation time of the used tool list is the machining program. If it is newer than the creation time of the tool, it is not necessary to create a new tool list, but in that case, the extraction method does not work, and the wasteful process of recreating the same tool list can be done. There is no.

Further, since the cursor is also displayed on the tool list used, the correction number on the tool list side will not be mistaken, and if the cursor on the tool list side is moved, the cursor on the correction amount side will be displayed. Automatically moves to the corresponding correction amount, so there is no need to operate the page key or cursor key, or the correction number does not have to be pressed and the cursor key is pressed. Can be selected.

Each means of the present invention can be realized by software using a computer, or can be realized by using a dedicated hardware circuit having each of these functions.

[0036]

As is apparent from the above description, according to the present invention, when a predetermined screen is displayed, the machining program number selected on the screen for executing machining and the extraction currently displayed. Unless the extraction program number of the data is the same and the extraction time is newer than the creation time of the machining program, data is newly extracted from the machining program selected on the screen for automatically executing machining. Troublesome operation is not required, and the correct correction amount can be set without wasteful operation.
