Description

INFORMATION PROCESSING DEVICE, MACHINE TOOL, AND INFORMATION PROCESSING PROGRAM

　　　　The present invention relates to a technique for adjusting image display settings between software applications that transmit and receive model data.

　　　　As a machine tool, e.g., a five-axis machine having three orthogonal straight axes (X axis, Y axis, and Z axis) and two rotating axes (B axis, C axis) is known. In such a machine tool, a numerical control device controls the five axes by executing an NC program (machining program) while changing the tip position and attitude of a tool to machine a workpiece into a desired shape.

　　　　NC programs are generated on the basis of tool location data (Cutter Location Data: hereafter referred to as CL data) obtained through computer-aided design (CAD) and computer-aided manufacturing (CAM). However, there are many models of numerical control devices, and different models have different specifications. Therefore, the CL data is appropriately converted by the CAM post-processor to provide an NC program optimized for each numerical control device.

JP 2019-070953 A

　　　　In general, post-processors are developed by CAM manufacturers or distributors. However, it is not easy for CAM manufacturers to develop post-processors that can be converted into NC programs that meet various specifications of each of numerical control devices.

　　　　Therefore, in recent years, manufacturers other than CAM manufacturers has been developing post-processors. However, the CAMs are of various different types. For this reason, developers need to consider the possibility that post-processor users are accustomed to one of the CAMs. This is because CAM users tend to use the post-processor without customization procedure, and in that case, if there is a large difference of usability between the CAM and the post-processor, the difference will affect the user's workability.

　　　　That is, when CL data is converted into an NC program by the post-processor, a simulation screen of the manufacturing process may be displayed so that the user can check whether the NC program operates normally. Furthermore, there is a case in which model data of a products created by CAD is displayed for confirmation. In this case, if the attributes related to the display of the image object or its description on the screen differ from those in CAD/CAM, the delay of user's recognition of the displayed content might degrade workability or the user might have a sense of incongruity.

　　　　One aspect of the present invention is an information processing device that generates NC programs used in machine tools. This information processing device includes: a data acquisition unit that acquires model data or CL data output from a CAM; a specific information acquisition unit that acquires specific information of the CAM; a program generation unit that generates the NC program on the basis of the CL data; an input unit that accepts user input; a display control unit that displays one of a simulation image, a three-dimensional image, and a two-dimensional image on the basis of at least one of the NC program, the model data, and the CL data, and changes a display mode of the displayed image according to the user input; and a setting unit that changes the setting of at least one of color, language, and wording in the display mode in accordance with the setting of the CAM on the basis of the specific information acquired by the specific information acquisition unit.

　　　　Another aspect of the invention is a machine tool. This machine tool includes: a data acquisition unit that acquires model data and NC programs generated by an external device; a specific information acquisition unit that acquires specific information of the external device; n input unit that accepts user input; a display control unit that displays one of a simulation image, a three-dimensional image, and a two-dimensional image on the basis of at least one of the NC program and the model data, and changes a display mode of the displayed image according to the user input; and a setting unit that changes the setting of at least one of color, language, and wording in the display mode in accordance with the setting of the external device on the basis of the specific information acquired by the specific information acquisition unit.

　　　　Yet another aspect of the invention is an information processing program that generates NC programs used in machine tools. This program causes a computer to implement: a function to acquire model data or CL data output from a CAM; a function to acquire specific information of the CAM; a function to generate the NC program on the basis of the CL data; a function to accept user input via an input unit; a function to display one of a simulation image, a three-dimensional image, and a two-dimensional image on the basis of at least one of the NC program, the model data, and the CL data, and change the display mode of the displayed image according to the user input; and a function to change the settings of at least one of the color, language, and wording in the display mode in accordance with the settings of the CAM on the basis of the acquired specific information.

　　　　The present invention can implement a similar sense of use between software applications that transmit and receive model data, thereby facilitating operation by the user.

　　　　Embodiments of the present invention will be described below with reference to the drawings.
　　　　It should be noted that for the following embodiments and modifications thereof, nearly identical components are denoted by identical symbols and their descriptions are omitted as appropriate.

　　　　FIG. 1 is a hardware configuration diagram of a machine tool according to an embodiment.
　　　　The machine tool 1 is, e.g., a five-axis control machining center, and is provided with a machining device 2 having three orthogonal straight axes (X-axis, Y-axis, and Z-axis) and two rotating axes (B-axis and C-axis). These five axes are simultaneously controlled by a numerical control device 52 to move the tool tip end point, and various machining operations are performed while changing the tool attitude.

　　　　The machine tool 1 includes an operation control device 50, the numerical control device 52, the machining device 2, a tool change unit 54, and a tool storage unit 56. The numerical control device 52 transmits control signals to the machining device 2 according to an NC program generated manually or automatically. The machining device 2 machines a workpiece (not shown) by driving the spindle and the table of the machining device 2 according to the instructions from the numerical control device 52.

　　　　The operation control device 50 includes an operation panel that provides a user interface function to the operator. The operator controls the numerical control device 52 via the operation control device 50. The tool storage unit 56 stores tools. The tool change unit 54 corresponds to the so-called ATC (Automatic Tool Changer). The tool change unit 54 takes out a tool from the tool storage unit 56 according to the change instruction from the numerical control device 52, and changes the tool in the spindle with the tool taken out.

　　　　The numerical control device 52 is connected to an information processing device 100. The information processing device 100 generates an NC program on the basis of the CL data acquired from the CAM and outputs the generated NC program to the numerical control device 52. The numerical control device 52 executes this NC program to control the machining device 2. The information processing device 100 may be configured as a part of the operation control device 50. The information processing device 100 may be a general laptop PC (Personal Computer) or a tablet computer.

　　　　FIG. 2 is a functional block diagram of the information processing device 100 illustrating an example of the invention.
　　　　Each component of the information processing device 100 is implemented by hardware including computing units such as central processing units (CPUs) and various computer processors, a storage device such as memories and storages, and wired or wireless communication lines that connects these units and devices, and software that is stored in the storage devices and supplies processing instructions to the computing units. Computer programs may be constituted by device drivers, operating systems, various application programs on upper layers thereof, and a library that provides common functions to these programs. Each of the blocks described below represents a functional block, not a hardware block.

　　　　It should be noted that each component of the operation control device 50 and the numerical control device 52 may also be implemented in a form of hardware including a computing unit such as a processor, storage units such as memory and storage, and wired or wireless communication lines connecting them, and software stored in a storage device to supply processing instructions to the computing unit.

　　　　The information processing device 100 includes an input/output interface unit 110, a data processing unit 112, a data storage unit 114, and a user interface processing unit 116. The input/output interface unit 110 is responsible for processing related to the input/output interface, including data exchange with external devices. The data storage unit 114 stores various programs and setting data. The user interface processing unit 116 is responsible for processing related to the user interface, such as image display and audio output, in addition to accepting operations from the user.

　　　　The data processing unit 112 performs various processes on the basis of the data acquired by the input/output interface unit 110, the data stored in the data storage unit 114, and the data acquired by the user interface processing unit 116. The data processing unit 112 also functions as an interface for the input/output interface unit 110, the data storage unit 114, and the user interface processing unit 116.

　　　　The input/output interface unit 110 includes an input unit 120 and an output unit 122.
　　　　The input unit 120 includes a data acquisition unit 124. The data acquisition unit 124 acquires CL data and model data from a CAM device 160. The output unit 122 includes a program output unit 126. The program output unit 126 outputs the NC program generated by the data processing unit 112 to the numerical control device 52.

　　　　The CAM device 160 acquires CAD data generated by a CAD device not shown, and acquires path generation information (coordinate system, tool shape, feed speed, and spindle rotational speed, among others). The CAM device 160 includes a CL data generation unit 162 and a data output unit 164. The CL data generation unit 162 generates CL data on the basis of the CAD data and the path generation information. The CL data includes the instructed position of the tool tip point and the instructed angle of the tool attitude.

　　　　The data output unit 164 outputs the generated CL data to the information processing device 100. The data output unit 164 also outputs the CAD data to the information processing device 100 as three-dimensional model data (also called "3D model data").

　　　　The data storage unit 114 includes a program storage unit 140, a specific information storage unit 142, and a display setting storage unit 144. The data storage unit 114 includes a memory that functions as a working area when the data processing unit 112 performs computing operations. The program storage unit 140 stores an information processing program for generating an NC program. The specific information storage unit 142 stores specific information of the CAM to be described later. The display setting storage unit 144 stores information related to display settings of the screen for each type of CAM (described later in detail).

　　　　The user interface processing unit 116 includes an input unit 150 and an output unit 152.
　　　　The input unit 150 accepts operation input from the user via a hardware device such as a touch panel, various keys, or handles. The output unit 152 provides various information to the user via image display on the display unit or audio output.

　　　　The data processing unit 112 includes a program generation unit 130, a specific information acquisition unit 132, a display control unit 134, and a setting unit 136. The program generation unit 130 functions as a post-processor and generates an NC program on the basis of the CL data acquired by the data acquisition unit 124.

　　　　In this embodiment, considering the workability when the user of the CAM uses the post-processor without customization procedure, the display settings of the CAM can be reflected in the display function of the post-processor. In other words, the information processing device 100 can change the display settings of the processor depending on the type of CAM according to the user demand. The program storage unit 140 stores an information processing program for changing display settings in the post-processor in accordance with the display settings of the CAM.

　　　　The specific information acquisition unit 132 acquires the specific information of the CAM possessed by the CAM device 160. The "specific information" here is set as information, e.g., the CAM name or ID, which can identify the type of CAM that generated the CL data. The specific information of the CAM is output from the CAM device 160 and acquired by the specific information acquisition unit 132 (see dotted line). The specific information storage unit 142 stores the acquired specific information. The display setting storage unit 144 stores specific information for each type of CAM and display setting information associated with the type of CAM (described later in detail).

　　　　The display control unit 134 controls the display of images on a display unit (not shown). The display control unit 134 causes the display unit to display a three-dimensional image or a two-dimensional image of a workpiece, a product (semi-finished products, finished products, and parts), a tool, a device part including a spindle, and the like on the basis of the acquired model data according to the user input. Further, the display control unit 134 causes the display unit to display a simulation image representing the machining process of the workpiece on the basis of the CL data and the model data. These images may contain descriptive wording (character string) for explaining the displayed object. The display control unit 134 changes the display mode (display position, display angle, display direction, and display size, among others) of the displayed image in response to user inputs.

　　　　The setting unit 136 acquires display setting information corresponding to the specific information from the display setting storage unit 144 according to user inputs. The CAM specific information stored in the specific information storage unit 142 is sent to the setting unit 136, and the CAM specific display setting information stored in the display setting storage unit 144 is sent to the setting unit 136. The setting unit 136 then changes the display settings of the image or character string to be displayed on the display unit in accordance with the display settings of the CAM on the basis of the specific information.

　　　　Next, the method of changing the display settings of the screen of the information processing device 100 will be described.
　　　　FIGS. 3A and 3B illustrate differences in display settings according to the type of CAM. FIG. 3A illustrates an example of display settings for color, and FIG. 3B illustrates an example of display settings for wording.

　　　　When a three-dimensional image, a two-dimensional image, or a simulation image is displayed on a display screen of a CAM, the background color is set and color-coded display may be made for each image object such as a spindle or tool. In addition, descriptions of these displayed images may be displayed as wording (character string). However, display settings may differ depending on the type of CAM.

　　　　For example, as shown in FIG. 3A, the display format (display settings) of each display element may differ among three types of CAMs: ACAM, BCAM and CCAM. The background color is set to white in ACAM, cyan in BCAM, and black in CCAM. The spindle color is set to gray in ACAM and BCAM, and green in CCAM. The tool color is set to yellow in ACAM, magenta in BCAM, and white in CCAM. The workpiece color is set to magenta in ACAM, yellow in BCAM, and red in CCAM.

　　　　Also, as shown in FIG. 3B, the wording used in each CAM may differ. A workpiece (material) before processing is designated as "stock" in ACAM, "material" in BCAM, and "workpiece" in CCAM. A jig for fixing, e.g., a workpiece is designated as "clamp" in ACAM, "jig" in BCAM, and "fixture" in CCAM.

　　　　In this way, the display settings may differ depending on the type of CAM. However, for the convenience of the user, it is desirable that the display settings of the CAM can be inherited by the post-processor. Therefore, in this embodiment, according to the selection by the user, the display settings of the screen when using the post-processor is changed to the display settings of the CAM, which is the output source of the CL data. The followings are the details of this process.

　　　　The display setting storage unit 144 stores a table (hereinafter also referred to as a "display setting table") which indicates the display settings of colors and wordings depending on the CAM specific information (i.e., for each type of CAM) such as shown in FIGS. 3A and 3B.

　　　　FIGS. 4 to 6B illustrate specific examples of display setting change processing. FIG. 4 illustrates an example of CL data. FIGS. 5A and 5B illustrate a processing screen when importing CL data. FIGS. 6A and 6B illustrate an operation screen for changing display settings manually.

　　　　As shown in FIG. 4, in this embodiment, the specific information is incorporated into the CL data in the CAM device 160 to enable the change of the display settings described above. The example shown in the figure incudes, in a predetermined block in the CL data written in the APT (Automatically Programmed Tool) language, the description of "OUTPUTSOURCE / {ACAM}" (see, bold characters). The description in the { } is the CAM name included as the specific information. In the example shown in the figure, "ACAM" is exemplified, but if the output source of the CL data is BCAM, the description will be "BCAM", and if it is CCAM, the description will be "CCAM".

　　　　When CL data is imported from the CAM device 160 to the information processing device 100, the import preview screen shown in FIG. 5A is displayed. At this time, the specific information acquisition unit 132 extracts the specific information from the CL data acquired by the data acquisition unit 124 and stores it in the specific information storage unit 142.

　　　　When the import is completed, the setting change selection screen shown in FIG. 5B is displayed. This setting change selection screen is a screen allowing the user to select whether or not the post-processor inherits the display settings of the CAM, and also displays the CAM name specified from the specific information. The user selects one of the buttons of "Yes" or "No" on the setting change selection screen.

　　　　If "Yes" is selected, the display settings of the post-processor is set or changed to the display settings of the CAM. If "No" is selected, the display settings of the post-processor will remain at the default settings without changing to the CAM display settings. In this embodiment, the default setting is a unique setting that does not depend on the type of CAM; however, the default setting may be the display settings of a CAM having a high market share. Display settings common to multiple CAMs may be given priority.

　　　　In the present embodiment, these display settings can also be changed afterwards. That is, when a user selects a setting button (not shown) displayed on the execution screen of the post-processor, the setting screen (dialog box) illustrated in FIGS. 6A and 6B is displayed, which allows the user to change the display settings.

　　　　In the example shown in the figure, the "color setting" tab of the setting screen is selected, so that the color setting screen is displayed (FIG. 6A). On the color setting screen, CAM SELECT button 210, ADD button 212, CHANGE button 214, and DELETE button 216 are provided. The CAM SELECT button 210 is used to select display settings for each CAM at once, and one of the CAMs can be selected from the pull-down menu 211 (FIG. 6B).

　　　　In FIG. 6A, ACAM is selected from the several types of CAMs, and the correspondence between color setting objects (display elements) and colors shown in FIG. 3A is shown. The user can use the ACAM display settings without change, but can add their own display settings by selecting the ADD button 212. Color settings may be added for a display element such as line drawing for which no color setting has defined. In addition, one of the already set display settings can be changed by selecting the CHANGE button 214. Further, any of the already set display settings can be deleted by selecting the DELETE button 216. In the case of deletion, the corresponding display element may become colorless (line drawing).

　　　　In addition, OK button 218, CANCEL button 220, and APPLY button 222 are provided on the setting screen. After the user has added, changed, or deleted any display settings, the addition, change, or deletion can be confirmed by selecting the APPLY button 222 and then selecting the OK button 218. The addition, change, or deletion can be canceled by selecting the CANCEL button 220. When display settings of one of the multiple types of CAMs is to be inherited without change, the user may select a desired CAM displayed in the pull-down menu 211 and then sequentially select the APPLY button 222 and the OK button 218.

　　　　When the "wording setting" tab is selected in this setting screen, a wording setting screen is displayed to show the correspondence between the wording setting object (display element) and the wording as shown in FIG. 3B. Since the user can change the wording settings as in the case of the color settings, the explanation is omitted.

　　　　Next, the flow of display setting processing is described.
　　　　FIG. 7 is a flowchart showing display setting processing.
　　　　As described above, the information processing device 100 imports CL data from the CAM device 160 in accordance with a user input (S10). At this time, the display control unit 134 causes the display unit to display the import preview screen shown in FIG. 5A (S12). The specific information acquisition unit 132 extracts specific information from the CL data and stores it in the specific information storage unit 142 (S14).

　　　　When the import of the CL data is completed, the display control unit 134 causes the display unit to display the setting change dialog shown in FIG. 5B (S16). At this time, if the user selects to change the display settings (i.e., if "yes" is selected) (Y in S18), the setting unit 136 refers to the display setting table on the basis of the specific information and acquires the display setting information of the corresponding CAM (S20). Then, the setting unit 136 sets the display settings of the post-processor so as to reflect the acquired display setting information (S22). If the user does not select to change the display settings (i.e., if "No" is selected) (N in S18), S20 and S22 are skipped.

　　　　The information processing device 100 has been described above on the basis of an embodiment.
　　　　The information processing device 100 of this embodiment changes the display mode of the three-dimensional image on the basis of the model data acquired from the CAM device 160 in accordance the with user request. The display settings of the post-processor can now be changed according to the display settings of the CAM on the basis of the specific information extracted from CL data. Therefore, display settings for images and wordings can be made common when CAM users use the post-processor without customization procedure, thereby improving the work efficiency of the user. That is, the post-processor can achieve the same feeling of use as the CAM, thereby facilitating operation by the user.

　　　　Although an embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and it goes without saying that various modifications are possible within the scope of the technical concept of the present invention.

　　　　Modifications
　　　　FIG. 8 is a functional block diagram of an information processing device 200 according to a modification.
　　　　The above embodiment exemplifies a configuration in which the CAM device 160 and the information processing device 100 are independent. In this modification, the CAD, CAM, and post-processor are incorporated in a common personal computer (PC).

　　　　The information processing device 200 includes a CAD/CAM unit 260 and a system management unit 280. The CAD/CAM unit 260 has both CAD and CAM functions and includes a model data generation unit 262, the CL data generation unit 162, and the data output unit 164. The model data generation unit 262 generates model data (CAD data) by the CAD function. The CL data generation unit 162 generates CL data on the basis of the CAD data and path generation information. The data output unit 164 outputs model data and CL data to the information processing device 100.

　　　　The system management unit 280 performs file management of software that implements each function of the information processing device 200. The system management unit 280 can check the software installed in the information processing device 200 by referring to the system file of the information processing device 200. In this modification, when a post-processor is installed, the specific information acquisition unit 132 inquires the system management unit 280 to acquire specific information indicating the type of CAM.

　　　　When the installation of the post-processor is completed, the display control unit 134 causes the display unit to display the setting change dialog shown in FIG. 5B. Then, if the user selects to change the display settings, the setting unit 136 acquires the display setting information of the corresponding CAM from the display setting storage unit 144 on the basis of the specific information and sets the display settings of the post-processor so as to reflect the acquired display setting information.

　　　　According to this modification, the display settings can be changed according to the display settings of the CAM on the occasion of the installation of the post-processor. As a result, the same effect as the above embodiment can be achieved. That is, the post-processor can achieve the same feeling of use as the CAM, thereby facilitating operation by the user.

　　　　When a CAD/CAM program is installed after the installation of the post-processor, the specific information acquisition unit 132 may acquire the specific information of the CAM on the occasion of the installation of the CAD/CAM program as described above. Then, the display settings of the post-processor may be changed according to the user input.

　　　　This modification exemplifies an example of using the file management function by the system management unit 280, but a process monitoring function can also be utilized. That is, the active CAM may be detected by process monitoring and the specific information of the CAM may be acquired.

　　　　Other modifications
　　　　In the above embodiment, an example of changing display settings of the post-processor is shown for the display settings when changing a display mode of a three-dimensional image based on model data. In a modification, the display settings may be changed similarly for a display mode of a two-dimensional image. The display settings may also be changed in the same manner for simulated images of a manufacturing process based on model data and CL data. Furthermore, the display settings may be changed in the same manner for the simulation image based on NC program converted from CL data.

　　　　The above embodiment exemplifies a configuration in which display settings of image display can be inherited in the relation between the CAM device and the information processing device. In a modification, the display settings may be inherited in the relation between the external device and the machine tool (information processing device). The external device may be a CAD device or a CAD/CAM device.

　　　　When the external device is a CAD device, display settings of a three-dimensional image or a two-dimensional image based on model data can be inherited by an information processing device incorporated in a machine tool as in the above embodiment. The information processing device may include a numerical control device, and those images may be displayed on a viewer or the like.

　　　　If the external device is a post-processor of the CAM device, the display settings of the image in the information processing device of the machine tool may be changed so as to conform with the display settings of the CAM device. The image may include a three-dimensional or two-dimensional image based on model data. Also, simulation images based on NC programs and model data may be included.

　　　　Specific information may be transmitted from an external device to an information processing device of a machine tool by file transfer. A post-processor constituting the external device may send specific information in the form of a display setting definition file conforming to the settings of the CAM. By using such a display setting definition file, the information processing device can inherit not only the default display settings of each CAM but also the setting contents of the display settings changed by a user for each CAM.

　　　　Alternatively, data (job data) containing, as specific information, identifying information such as a CAM name may be transmitted. An information processing device of a machine tool may request specific information from an external device, and the external device may transmit specific information accordingly. A network shared folder between the external device and the machine tool may be provided to store specific information.

　　　　Alternatively to the above embodiment in which the CAD device and the CAM device are separately configured, these devices may be configured as a CAD/CAM device having both CAD and CAM functions.

　　　　In the above embodiment, the information processing device is a post-processor, the information processing device may be a second CAD/CAM device (CAD/CAM device-2). For example, it is assumed that an NC program generated by CAD/CAM-1 installed in PC-1 is loaded into CAD/CAM-2 of PC-2. In such a case, the display settings may be changed by the method of the above embodiment or modification in order for CAD/CAM-2 to inherit the display settings of CAD/CAM-1. Instead of the second CAD/CAM device, CAM device-2 having no CAD function may be employed.

　　　　In the above embodiment, colors and wordings are exemplified as the display mode of an image; however, description language such as Japanese or English may also be subject to setting changes. That is, if the language setting of the CAD/CAM is Japanese, the language setting of the information processing device (post-processor) may also be changed to Japanese on the basis of specific information.

　　　　In the above embodiment, the machine tool is exemplified as a machining center that moves a rotating tool relative to a workpiece; however, the machine tool can be a turning center that moves a tool relative to a rotating workpiece or can be an additional processing machine that laminates materials while melting them with a laser. In addition, the machine tool may be a combined processing machine having these functions in combination.

　　　　Although not described in the above embodiment, the information processing program described above may be recorded in/on and provide as a computer-readable recording medium.

　　　　The present invention is not limited to the embodiments described above and modifications thereof, and any component thereof may be modified and embodied without departing from the scope of the invention. Components described in the embodiments and modifications may be combined as appropriate to form various embodiments. Some components may be omitted from the components presented in the embodiments and modifications.
