BEST MODE FOR CARRYING OUT THE INVENTION Exemplary embodiments of the present invention will be described in detail below with reference to the drawings. However, the components described in the following embodiments are merely examples, and the technical scope of the present invention is not limited to them.

[First embodiment]
FIG. 1 is a block diagram showing the configuration of an information processing apparatus according to the first embodiment.
The information processing device 100 is a device for generating a first NC program 130 as a program used in machine tools. Information processing apparatus 100 includes NC code receiving portion 101, first converting portion 102, CL data receiving portion 103, CL data interpreting portion 104, input receiving portion 105, second converting portion 106, code transmitting portion 107, and storage portion 108. include. The program is preferably a program used in a machine tool, such as machining (machining program), transportation of tools and workpieces (transportation program), measurement, and photography.

The NC code receiving section 101 receives a second NC program 150 from the outside. The first conversion unit 102 converts the second NC program 150 into CL data 153 . The CL data receiving section 103 acquires the CL data 153 and the CL data interpreting section 104 interprets the CL data 153 .

The input accepting unit 105 accepts selection of a code (executable code) that can be executed by the machine tool based on the user's operation input via the GUI screen 170 . As the GUI screen 170, for example, the illustrated function selection dialog is displayed. In this function selection dialog, when the accuracy priority (one function) is selected as shown in the figure, the input of the execution code corresponding to the accuracy priority (PROCMOD/FIN, G332R3, etc. code specifying finishing machining) is accepted. It will be. Here, "PROCMOD/FIN" is an example of CL data execution code, and "G332R3" is an example of NC code execution code.

Based on the interpretation of the CL data 153 by the CL data interpretation unit 104, the second conversion unit 106 converts the CL data 153 including the execution code and the NC program including the execution code. When the second conversion unit 106 converts the CL data 153 including the execution code, the second conversion unit 106 further converts the CL data 153 into the first NC program 130 . Of course, the second conversion unit 106 may directly convert to the NC program including the execution code without converting it to the CL data 153 including the execution code. The storage unit 108 stores the first NC program 130, but may also store other NC programs inserted from the outside. The code transmission unit 107 transmits the first NC program 130 to the numerical controller of the machine tool. Note that a configuration without the code transmission unit 107 may be used, and for example, a configuration in which the NC program can be output to a storage medium such as a USB may be used.

In the present embodiment, the information processing apparatus has been described. In other words, it can be realized not only by an information processing device but also by a program or an application.
Also, in this embodiment, the information processing apparatus has a GUI screen, but the GUI screen may be displayed on the screen of the terminal PC via the Internet, and the information processing apparatus may be provided separately from the terminal PC. The storage unit of the information processing apparatus of this embodiment may be provided in another second information processing apparatus. If there is an external storage unit, a program acquisition request may be transmitted to the external storage unit, and if the requested program is stored in the storage unit, the program may be transmitted from the storage unit to the information processing apparatus.

FIG. 2 is a block diagram showing the configuration of an information processing device according to a modification.
In the first embodiment, only the NC program (second NC program) is externally acquired, and the CL data obtained by inversely converting the NC program is interpreted. In this modified example, it is also possible to acquire the NC program and CL data from the outside. That is, the CL data receiving unit 103 can acquire the CL data 145 from the outside. The CL data interpretation unit 104 interprets not only the CL data converted from the NC program, but also the CL data 145 transmitted from the outside.

[Second embodiment]
FIG. 3 is a block diagram showing the configuration of an information processing apparatus according to the second embodiment.
The information processing device 200 is a device for generating an NC program 230 (first NC program) used by the numerical control device 220 . Numerical control device 220 is a device that mainly numerically controls machining in machine tool 210 , and includes an NC code interpretation unit 221 that interprets NC program 230 and a command output unit 222 that outputs control commands to machine tool 210 .

Examples of the machine tool 210 include a machine that performs additive manufacturing on a work, a machine that performs subtractive manufacturing on a work, and a machine that processes by irradiating light such as a laser. Specifically, lathes, drilling machines, boring machines, milling machines, gear cutting machines, grinders, multi-axis processing machines, laser processing machines, lamination processing machines, etc. are numerically controlled based on NC programs, Any machine that performs various processing such as turning, cutting, drilling, grinding, polishing, rolling, forging, bending, forming, fine processing, and lamination processing on a work of wood, stone, resin, or the like may be used. Furthermore, the machine tool may have a measurement function, and may be configured to be able to measure the dimensions of the workpiece using a measuring instrument such as a touch probe or a camera.

The machine tool 210 is, for example, a three-axis machine, and includes a main shaft motor 211 and a feed shaft motor 212 as machine elements. A spindle motor 211 rotates the tool, and a feed shaft motor 212 linearly moves the table in the X and Y axis directions via a ball screw or the like, or linearly moves the tool or the table in the Z axis direction. The machine tool 210 may of course be a 5-axis machine.

The spindle motor servo controller 213 controls the spindle motor 211 based on control commands from the command output unit 222 . The feed shaft motor servo controller 214 controls the feed shaft motor 212 based on control commands from the command output unit 222 .

Each component of the information processing apparatus 200 is implemented by software that supplies processing instructions to arithmetic units such as a CPU (Central Processing Unit) and various computer processors. Each block such as a code filter section and a CL data interpretation section, which will be described below, represents a functional unit block.
The information processing apparatus 200 includes an NC code acquisition unit 201, a code filter unit 202, a first conversion unit 203, a CL data interpretation unit 204, a change acceptance unit 205, a second conversion unit 206, a code transmission unit 207, a storage unit 208, and a display. 209.

The NC code acquisition unit 201 acquires the NC program 250 (second NC program) generated by the CAM device 240 . The CAM device 240 has a main processor section 241 and a post-processor section 242 . The main processor unit 241 generates CL data 243 based on shape data obtained from a CAD device 260 (Computer-Aided Design). A post-processor section 242 generates an NC program 250 from the CL data 243 .

The storage unit 208 stores various program modules. The processor of the information processing device 200 realizes the functions of each unit by executing various program modules. The storage unit 208 also stores the correspondence between the NC code and the CL data. The code filter unit 202 performs filtering for removing codes that do not have corresponding CL data (also referred to as “non-corresponding codes”) among the NC codes included in the NC program 250 . After that, inverse conversion into CL data by the first conversion unit 203 and interpretation of the CL data by the CL data interpretation unit 204 are executed. In this embodiment, the code filter unit 202 and the first conversion unit 203 are described as separate functions, but the first conversion unit 203 may include the code filter function. For example, the first conversion unit 203 sequentially converts NC program codes into CL data. The first conversion unit 203 deletes the non-corresponding code when the order of the non-corresponding code is reached in the course of the processing. Then, the first conversion unit 203 reaches the code next to the non-corresponding code in the NC program, and if the next code is the corresponding code, converts it into CL data. When the non-corresponding code reaches the conversion order, the first conversion unit 203 repeats the above-described processing for each non-corresponding code that reaches the conversion order, so that the code filter function is included.

Although the correspondence relationship between the NC code and the CL data is stored in the storage unit 208 of the information processing apparatus 200 in this embodiment, it may be stored outside the information processing apparatus 200 . It is preferable that the correspondence relationship between the NC code and the CL data is prepared in advance. For example, G00, G01, G06, etc. whose functions are specified in ISO 6983-1:2009 or JIS B 6315-1:2013 can be pre-associated with corresponding CL data. In addition, even for G100 to G999 where functions are not specified in ISO 6983-1:2009 or JIS B 6315-1:2013, some G codes specify functions executable by machine tools, Corresponding CL data can be created and the NC code and CL data can be associated. For reference, codes whose functions are specified in JIS B 6315-1:2013 include G00 to G04, G06, and G09. Codes with unspecified functions in JIS B 6315-1:2013 include G100 to G999. Further, codes not assigned by JIS B 6315-1:2013 include G1000 to G1100.

In addition, in the case of filtering for deletion as in the present embodiment, a list of NC codes to be deleted is stored without using the data of the correspondence relationship between the NC code and the CL data, and the filtering for deleting the corresponding code is performed. It may be a process to be performed.

The first conversion unit 203 reversely converts the filtered NC program 250 into CL data 253 written in APT (Automatically Programmed Tools). APT is a programming language developed for numerical control of machine tools, and can automatically determine tool paths and machining procedures based on the shape of machine parts to be manufactured. EXAPT (extended subset of APT), which is a more precise improvement of the tool path determination function of APT, may be used. Generally, the post-processor converts from APT to NC, but the first conversion unit 203 performs an inverse conversion from NC to APT.

Also, when converting an NC program into CL data, it is preferable to classify and convert by a certain source. For example, assume that there is an NC program that performs machining and measurement. The first conversion unit 203 groups the CL data of processing and the CL data of measurement, and converts them into CL data in such a manner that they can be distinguished from each other. In this way, when receiving a change input of the measurement point or the number of times of measurement on the GUI screen, it is possible to shorten the time required to determine which CL data is to be changed. Also, by grouping and dividing processes in this way, it is possible to present a program change option that can be optimized for the machine tool used from the group and process information.

The CL data interpretation unit 204 interprets CL data 253 after inverse conversion, that is, CL data written in APT (hereinafter also referred to as "APT data").

The change acceptance unit 205 accepts an input of execution code that can be executed by the machine tool 210 with respect to APT data. The execution code that can be executed by the machine tool 210 includes a function code that implements a function specific to the machine tool 210 or the numerical controller 220, a function code that implements specific functions such as processing such as finishing, camera photography, and measurement. and so on. The display unit 209 displays a GUI screen, which will be described later, when accepting the execution code.

The second conversion unit 206 converts the CL data 253 (APT data) into the NC program 230 including the execution code accepted by the change acceptance unit 205 . This NC program can also be said to be an optimized program. Code transmission unit 207 transmits NC program 230 to numerical controller 220 .

Here, optimization processing means benefits to machining such as shortening of machining time, improvement of machining accuracy, saving of power and coolant, efficient removal of chips, efficiency improvement by visualization of process management, measurement processing, etc. It is a concept that includes all processes that bring about Specifically, the optimization processing includes (1) to (4) shown below, but is not limited to these.

(1) Optimization of servo characteristics If machining modes such as the following (a) to (d) are implemented by a custom macro, specify the desired machining mode to optimize machining accuracy and machining time. be able to.
(a) Time priority mode: A mode that prioritizes shortening the machining time. It is used when the required accuracy is low, such as rough machining.
(b) Intermediate mode: A mode intermediate between the time-priority mode and the precision-priority mode. Used for semi-finishing that requires high accuracy and short time.
(c) Accuracy priority mode: A mode that prioritizes improvement of machining accuracy. Used when machining accuracy and surface finish are required.
(d) Accuracy top priority mode: A mode that gives higher priority to machining accuracy than the accuracy priority mode.

(2) Automatic optimization of servo characteristics If the function to automatically adjust the servo is implemented by PLC, measure the mass and moment of inertia of the workpiece and jig, and set the optimum acceleration/deceleration based on the feedback value. . Specifically, when the mass of the workpiece or jig is heavy and the moment of inertia is large, acceleration/deceleration is suppressed to achieve stable positioning. On the other hand, if the mass of the workpiece or jig is light and the moment of inertia is small, the acceleration/deceleration can be maximized to shorten the machining time.

(3) Optimization of on/off control of chip conveyor If the on/off function of the chip conveyor that discharges chips is implemented by PLC, the volume of chips over time is calculated by machining simulation, Optimize the on/off control of the chip conveyor according to the quantity. Specifically, by turning off the chip conveyor during non-cutting or when the amount of chips is small, the driving power of the chip conveyor is saved and the efficiency of cutting oil usage is improved.

(4) Optimization of process management If a function is implemented to tag the same machining with a common machining process ID between the NC viewers of the HMI of the CAM device, information processing device, and machine tool, function, and process control is optimized.
・A function to display or update the changed points in the post-process ・A function to highlight the changed points when operating the machine tool ・A function to stop with the previous positioning command function to update the changes to the previous process

Storage unit 208 stores program modules that implement NC code acquisition unit 201 , first conversion unit 203 , CL data interpretation unit 204 , change reception unit 205 , second conversion unit 206 and code transmission unit 207 . The storage unit 208 also stores the correspondence information between the NC code and the CL data, the command table, the machine tool information, the numerical controller information, and the like. Here, the command table is a table showing the correspondence relationship between standardized format commands and arguments and NC codes.

The machine tool information is information on various machine tools of different machine tool manufacturers and models, such as the machine origin, model stroke length, machine specific command G code, M code (Mxx, Mxy), etc. May include the following information:
(1) Machine tool model number (2) Optional information (number of turrets, spindle diameter, types and presence/absence of servos and chip conveyors, types and presence/absence of measuring devices)
(3) Usable tool types (e.g. drills, end mills)
(4) Number of pots in magazine and pot numbers

Also, the optimization processing may be performed based on the G-code defined by ISO. For example, there are G codes common to all CAM devices such as G00, G01, G02 and G03 (defined by ISO). The change receiving unit 205 can also perform optimization processing that provides an optimization function based on such ISO-compliant G-code.

Although the code filter unit 202 of this embodiment filters and deletes non-corresponding codes, the present invention is not limited to this. The configuration may be such that the user can select from the following two options. It is desirable that the G/M code filter be in a form that can be edited by the operator.
Selection 1: Output as is Selection 2: Delete the code in the G/M code filter

The information processing apparatus 200 may further include a setting unit that sets whether or not to delete the non-compliant code from the NC program. The code filter unit 202 may filter the NC program according to the setting contents of the setting unit.

FIG. 4 is a diagram showing a specific example of processing up to optimization of the NC program.
In this example, the second NC program 250a is output from the post-processor section 242a of the CAM device 240a. The first conversion unit 203 has code filter means corresponding to a code filter unit, and deletes non-corresponding codes (codes without corresponding APT data) from the second NC program 250a. FIG. 4 shows an example in which M51 is deleted before CL data conversion because M51 corresponds to a non-corresponding code. The G code and M code corresponding to non-corresponding codes are stored in the code list in advance.

The first conversion unit 203 further inversely converts the filtered NC program 250a into CL data 253 (APT data). The CL data interpreter 204 gives an interpretation result 501 to the CL data 253 . Note that the example in FIG. 4 is merely conceptual, and does not mean that the data is added in Japanese. The CL data interpretation unit 204 interprets the CL data, but the display is still in NC code so that the flow of processing can be easily understood.

The change receiving unit 205 displays a GUI screen 270 for allowing the user to select whether or not to insert the cutting mode setting code 502 of G332 immediately before the cutting start code G01 for optimization. The GUI screen 270 can be displayed, for example, as a function selection dialog as shown in the drawing, and can accept selection of codes executable by the machine tool. When the accuracy priority is selected in the function selection dialog shown in the figure, it means that the input of G332R3 (described later) has been accepted.

The change accepting unit 205 accepts user's selection via the GUI screen 270 . This optimizes the machining before cutting begins. The codes G01 and G332 referred to here may be the NC program codes themselves, or the CL data codes corresponding to the NC program codes.

For example, G332 is an NC code for selecting the machining mode (cutting mode) of (a) to (d) described above. Specifically, in the NC program, one of "G332R1", "G332R2", "G332R3", and "G332R4" is inserted immediately before the cutting start code G01. Arguments R1 to R4 are set in the following cases.
R1: Set during rough machining (time priority mode)
R2: Set for semi-finishing (intermediate mode)
R3: Set when finishing (precision priority mode)
R4: Manually set by the user only when desired (precision first priority mode)

For example, when OPTYPE/ROUGH (rough machining) is set as an execution code in APT data, a G code of G332R1 and an argument are inserted. On the other hand, when OPTYPE/FINISH (finishing) is set as an execution code in APT data, a G code of G332R3 and an argument are inserted.

In this example, when the NC program code is G332R1, the CL data code corresponding to the NC program code is OPTYPE/ROUGH (rough machining). Similarly, when the NC program code is G332R3, the CL data code corresponding to the NC program code is OPTYPE/FINISH (finishing).

G332 is an unspecified code in JIS as described above. This allows machine tool and numerical controller vendors to specify functions for individual applications. Therefore, it is possible to specify a function specific to a specific machine tool or a function specific to a specific numerical controller. This time, by generating an NC program including the G332 execution code, it is possible to realize optimization suitable for the machine tool to be used.

The information processing apparatus 200 deletes or ignores (comments out) preset function codes among function codes whose functions are not specified in ISO 6983-1:2009 or JIS B 6315-1:2013 from the program before processing. ). A starting point code (starting point data) serving as a starting point among a plurality of codes included in the program before processing is detected, and the code corresponding to the starting point code is presented to the user as an execution code (additional code). When the user makes a selection via the GUI screen 270, the change receiving unit 205 performs processing for adding an execution code corresponding to the origin code.
Based on the pre-processing CL data 253 (pre-processing CL data) before the execution code is added, the post-processing CL data (post-processing CL data) to which the execution code is added, Convert to NC program 230 .

For reference, codes whose functions are specified in JIS B 6315-1:2013 are G00 to G04, G06, G09, M00 to M06, M10, and the like. In addition, although M07 to M09 are not described in JIS B 6315-1:2013, they are defined in other ISO and the like. If it is M07, it is described as "See ISO/TR 6983-2."

Codes whose functions are not specified in JIS B 6315-1:2013 are G05, G07, G50 to G52, G100 to G999, and the like. This G-code is numbered in JIS B 6315-1:2013, but the function is described as unspecified. Codes whose functions are not specified in JIS B 6315-1:2013 include codes such as M51 and M59 that are not described in JIS B 6315-1:2013.

[Modification]
FIG. 5 is a diagram showing a specific example of processing of the NC program according to Modification 1. As shown in FIG.
In this modified example, the NC program 250 a (second NC program) is reverse-transformed by the transforming means, which is the first transforming unit 203 . Then, the converted CL data 253 (APT data) is interpreted by the interpretation means, which is the CL data interpretation unit 204 . The CL data interpretation unit 204 also detects the process, the correspondence between the code and the process, the meaning of each code, the origin code, and the like. The conversion means, which is the second conversion unit 206, adds the code corresponding to the selection input by the user on the GUI screen to the location associated with the starting point code detected by the CL data interpretation unit 204 to generate the NC program.

In this modified example, the CL data to which the code of the CL data corresponding to the input received by the change receiving unit 205 is added is not generated, but is directly converted into the NC program. That is, the second conversion unit 206 generates an NC program based on the pre-processing CL data 253 (pre-processing CL data) before addition of the execution code and the input received by the change receiving unit 205. be.

FIG. 6 is a diagram showing a specific example of processing of the NC program according to Modification 2. As shown in FIG.
In the second embodiment, the non-corresponding code (code with no corresponding APT data) is deleted from the NC program 250a (second NC program) and not included in the NC program 230a (first NC program).

In this modification, when an incompatible code is detected in the NC program 250a, it is temporarily ignored (commented out). In FIG. 6, since M51 is an unsupported code, the first conversion unit 203 shows an example in which "//" is added in front of M51 to comment it out. On the other hand, similarly to the second embodiment, the change accepting unit 205 accepts user's selection via the GUI screen 270 . Furthermore, the display unit 209 displays the GUI screen 272 when converting the CL data 253 after the change processing into the NC program 230a. In FIG. 6, the GUI screen 272 is the execution code selection dialog, and the code commented out in the first conversion process is displayed. Codes M51, M59, G05, and G22 are displayed in the execution code selection dialog of FIG. The user can restore the ignored code (ignored code) via this GUI screen 272 .

At this time, if the ignore code is selected by the user, the second conversion unit 206 uses the ignore code (M51 in the illustrated example) as the NC code (execution code) when converting the CL data 253 into the NC program 230a. Build in and generate an NC program. On the other hand, since G05, G22 and M59 were not selected, there was no input to restore them, so the second conversion unit did not generate an NC program including G05, G22 and M59.

FIG. 7 is a diagram showing a specific example of processing of the NC program according to Modification 3. As shown in FIG.
In this modified example, the GUI screen 270, which is part of the change receiving unit 205 in the second modified example, is not displayed. The CL data interpretation unit 204 interprets the CL data 253 (APT data) and detects the origin code G01. The second conversion unit 206 generates an NC program in which the execution code G332 corresponding to the origin code G01 is inserted. The second conversion unit 206 shown in FIG. 7 first generates processed CL data in which CL data corresponding to the execution code G332 (corresponding CL data) is inserted. Then, the second conversion unit 206 performs conversion processing based on the processed CL data into which the corresponding CL data has been inserted, and further inserts the NC code (M51 in the illustrated example) selected in the execution code selection dialog. to generate the first NC program 230a.

FIG. 8 is a diagram showing an execution code setting screen according to Modification 4. As shown in FIG.
In this modified example, the change accepting unit 205 accepts user operation input via the execution code setting screen 600 . Thereby, the machining program (NC program) is optimized before starting cutting. The execution code setting screen 600 includes a work display screen 602 in the upper part and a process setting screen 604 in the lower part.

The work display screen 602 displays the shape of the work based on the CAD data, and the feature numbers are assigned so as to overlap along the shape. The "feature" here represents a process such as machining or measurement, and includes geometrical features that characterize the machining process. A feature number corresponding to a machining process is indicated by a circle frame, and a feature number corresponding to a measurement process is indicated by a square frame so that they can be distinguished from each other.

On the process setting screen 604, the result of analyzing the NC program or CL data is divided and displayed on a feature basis, and columns for feature number (No.), feature content, function, function advisor, and the like are provided. The items displayed in each column can be arbitrarily selected by the user's operation input such as tapping on the screen or clicking the mouse.

Each feature number corresponds to a processing step number. The column of "details of feature" indicates the type of processing such as processing and measurement and its details. The "function" column shows settings related to optimization processing. The "Function Advisor" column displays the code filtered by the filtering function. If the filtered code is a code that can be used with the machine tool, the function description and the filtered code are displayed as input support.

In the example of FIG. 8, features 1 to 8 are set as the first process, features 9 to 12 are set as the second process, and features 13 and 14 are set as the third process. Feature 1 is a process in which the workpiece is turned from the right side of the end face to be machined to a set outer diameter (feature content), and "time priority" is set as optimization processing (function). For feature 1, M59 is displayed as the filtered code and "high pressure chuck ON" is shown as the function description. M59 is a code that can be used on the machine tool in question, but is filtered in the illustrated state.

Feature 8 is a step of performing tool measurement upon tool storage (feature content). For feature 8, G523 is displayed as the filtered code and "image measurement" is shown as the description of the function. G523 is also a code that can be used on the relevant machine tool, but is filtered in the illustrated state.

Feature 9 is a process of turning the workpiece from the right end face to machine it to a set inner diameter (feature content), and "time priority" is set as optimization processing (function). For feature9, G22 is displayed as the filtered code. Since G22 is a code that does not correspond to the relevant machine tool, no explanation of the function is displayed.

In the column of "function", one of time priority, intermediate and accuracy priority is displayed. "Time Priority" corresponds to the time priority mode described above, "Intermediate" corresponds to the intermediate mode, and "Accuracy Priority" corresponds to the accuracy priority mode. It should be noted that "precision first priority" corresponding to the precision first priority mode may be set.

An edit button 610 , a save button 612 , an add button 614 , a delete button 616 , an invalidate button 618 and a reconstruct button 620 are provided below the process setting screen 604 . When a setting item is selected for each feature by the user's operation input, the setting content can be corrected by tapping these buttons (details will be described later).

9 to 14 are diagrams showing a specific method of operating the execution code setting screen.
Note that the marks (pointing marks) imitating a human hand in each figure are images representing selection of items by the user, and do not actually appear on the screen. The numbers attached to the pointing marks (FIG. 10, etc.) indicate the order of selection by the user. When the user performs operation input, a cursor may be displayed at the position of the pointing mark.

As shown in FIG. 9, the "details of feature" column has three columns: a left column, a center column, and a right column. The left column displays the outline (outline) of the processing, the center column displays the processing to be executed, and the right column displays the specific contents of the processing.

"End face right" in the left column means cutting the work from the right end face, and "End face left" means cutting the work from the left end face. When the user touches "end face right", it is changed to "end face left". In that case, the feature whose machining position is on the left side of the changed feature is automatically changed to "end face left". In the example of FIG. 9, feature 6 is changed to "end face left" by the user's touch, so feature 7 is automatically changed to "end face left". If you touch "end face left", it will be changed to "end face right". In that case, the feature whose processing position is on the right side of the changed feature is automatically changed so as to cut from the right side of the end face.

In the middle column, types of processing such as processing and measurement are displayed, and processing types such as "turning" and "drilling" are displayed for processing processing. In the right column, processing locations such as "outer diameter" and "inner diameter" and processing shapes such as "outer diameter groove" and "inner diameter groove" are displayed. Measurement objects such as "grooves" and "holes" are displayed for measurement processing. For example, feature 12 is a step of drilling a specific pattern. Feature 13 is a step of measuring the groove formed on the right side of the end face. Feature 14 is a step of measuring a hole machined in a specific pattern.

Touching an item in the "function" column switches the contents of the optimization process in order. That is, when "time priority" is touched, the display is changed to "intermediate", and when "intermediate" is touched, the display is changed to "accuracy priority". If you touch "Accuracy Priority", the display will change to "Time Priority". These displays make it easy for the user to grasp which feature's optimization process is being changed and how. When these settings are saved, the settings are reflected in the NC program. Note that the internal CL data is actually changed.

In the "Function Advisor" column, touching the displayed item restores the function that was disabled or ignored. In the example of FIG. 9, although feature 1 "high pressure chuck ON (M59)" and features 13 and 14 "image measurement (G523)" were once filtered, the functions were restored by the user's touch (underlined and in bold)

As shown in FIG. 10, it is also possible to edit individual features directly. For example, when feature 8 is selected and the edit button 610 is tapped, a pop-up window 622 corresponding to that feature is displayed, displaying specific NC codes, CL data, and the like. In addition, in the example of FIG. 10, the NC code and its comment are displayed. The user can edit the code directly. A pop-up window (622) on the upper side of the figure shows the code before editing, and a pop-up window 622 on the lower side shows the code after editing. By tapping the save button 612 after editing, the edited state can be saved. Thereby, the setting of the NC program becomes the setting after editing.

In feature 8 shown in FIG. 10, items of G523 that have been filtered are displayed in the column of "function advisor". When the user selects this item, G523 is highlighted as shown in Figure 11 to indicate that the code has been reinstated. In the example of FIG. 11, this highlighting is indicated by underlined bold letters, but it may be highlighted or otherwise indicated. In the example of FIG. 10, the code was edited in feature 8 and changed from "M33 R1" to "M33 R2". there is Although G22 is not compatible with the relevant machine tool, it can be revived by editing the code.

As shown in FIG. 12A, on the process setting screen 604, it is also possible to move the feature unit (that is, the process) up and down. This movement can be done by tapping the arrow button on the far right of the feature. In the illustrated example, feature7 and feature6 are moved downward, and feature13 is moved upward. That is, the order of features can be changed.

It is also possible to move a group (a plurality of features) such as the first process and the second process. In that case, tap the arrow button on the right end of the first step or the like. Note that in the example of FIG. 12A, the order of feature7 and feature6 is changed compared to the screen of FIG. This is because features 6 and 7 are switched to "end face left", and as a result, turning is performed from the end face located further to the left.

As shown in FIG. 12B, part of the entire process can be folded and hidden. In the illustrated example, the first process and the second process are collapsed on the process setting screen 604, and features 2 to 8 of the first process and features 10 to 14 of the second process are hidden. This folding process can be executed by tapping a triangular button (also called a "folding button") on the right side of each step. When the folding process is performed, the direction of the triangular mark on the folding button is reversed, and the notation changes.

Note that the first feature in the folding process is displayed as it is, such as feature 1 in the first process and feature 9 in the second process. In particular, in the case of processing, it is easy to predict what processing will be included in the process if it is known what kind of processing is to be started. By tapping the collapse button again, the process thus collapsed can be expanded and redisplayed.

As shown in FIG. 13, unused feature units can also be disabled. In the illustrated example, these steps have been disabled by selecting feature 12 and feature 14 and selecting disable button 618 . By tapping the reconfiguration button 620 after invalidation, the invalidated process is deleted and the NC program is constructed with the optimized feature configuration. A new feature can also be added by tapping the add button 614 . Any feature can also be deleted by selecting it and tapping the delete button 616 .

As shown in FIG. 14, the change receiving unit 205 constructs the feature configuration of the new program based on the editing as described above. Each feature is replaced with a sequence number that is the order of the post-editing process. The second conversion unit 206 converts the information into an NC program.

In this modification, after the first conversion unit 203 converts the NC program 250 into CL data 253 (unprocessed CL data), the CL data interpretation unit 204 interprets the CL data 253 and decomposes it into features. The change receiving unit 205 displays the process setting screen 604 (execution code setting screen 600) and edits the feature based on the user's operation input. The second conversion unit 206 converts the CL data (post-processed CL data) including the execution code based on the editing result of the feature into the NC program 230 .

In another modification, the execution code may be edited by interpreting the NC program instead of the CL data. That is, the program interpretation section may interpret the NC program 250 (unprocessed NC program) and decompose it for each feature. The change receiving unit displays the process setting screen 604 and edits the feature based on the user's operation input. The program conversion section generates an NC program 230 (post-process NC program) to include an execution code based on the edited result of the feature.
