Description

In order to machine a workpiece into a desired shape, it is necessary to operate a machine tool using a numerical control device that quantifies and controls the moving distance of the tool. For example, an operator selects a tool according to the material and machining shape of the workpiece, attaches it to the machine tool, sets and corrects the coordinate origin, and inputs a program created using CAD/CAM software for setup work. to implement. Numerical control systems using a simulation device have been proposed that omit this setup work, read a known machining program, and send a command for simulating a machining operation to a numerical controller.

FIG. 2 is a flowchart of processing of the numerical control system 10 according to the first embodiment. The processing from step S101 to step S110 is performed by the simulation device 100, and the processing from step S201 to step S206 is performed by the numerical control device 200. FIG.

First, the first NC data transmission/reception unit 101 acquires NC data from the numerical controller 200 (step S101). Next, the first setting holding unit 107 holds the NC data received from the first NC data transmitting/receiving unit 101, and transmits it to the simulation executing unit 104 (step S102).

Next, the setting information acquisition unit 103 acquires the setting information input by the user, and transmits it to the simulation execution unit 104 (step 103). Next, the instruction acquisition unit 102 acquires instruction information for operating the machine tool on the simulation, and transmits it to the simulation execution unit 104 (step S104). In FIG. 2, step 103 is performed before step 104, but the order may be reversed.

Next, the data changing unit 111 changes the setup machine tool motion data of the acquired NC data with the acquired instruction information to generate changed setup machine tool motion data (step S105). Next, the simulation unit 112 simulates the operation of the machine tool during setup based on the changed NC data including the changed setup machine tool operation data and the setting information, and simulates the machining state during machining after completion of the setup (step S106).

If the NC data is changed during the simulation (step S107 Yes), the data changing unit 111 transmits the changed NC data to the first setting holding unit 107 to update the NC data (step S108). If the NC data has not been changed (step S107 No), the process proceeds to step S109.

Next, the judging unit 113 judges whether or not the user has input whether or not the processing is desired. create (step S110). If it is not determined that the processing is desired (step S109 No), the process returns to step S104.

For example, if the setup machine tool motion data acquired from the numerical controller 200 includes data related to tool movement during setup, and the machine tool is operated with the setup machine tool motion data as it is, the housing of the machine tool and the May interfere with tools. In such a case, instead of proceeding to step S110 in step S109, it is sufficient to return to step S104 and reacquire the instruction information regarding the operation of the machine tool. In step S104, the instruction information is acquired, the setup machine tool operation data is changed (step S105), and the simulation is performed again (step S106). selects OK in step S109, and proceeds to operation procedure data creation (step S110).

Furthermore, even if the interference can be avoided, if the operation is inefficient, the simulation may be redone. The user repeatedly tries the operation of the machine tool until both interference avoidance and productivity can be achieved in the simulation (steps S104 to S109).

Next, the second NC data transmission/reception unit 201 acquires NC data from the simulation device 100 and transmits it to the second setting holding unit 203 (step S201).

Next, the data acquisition unit 206 of the numerical controller 200 acquires the operating procedure data 108 output from the simulation device 100, and transmits it to the operating procedure screen creation unit 204 (step S202). Next, the operating procedure screen creation unit 204 creates operating procedure screen data from the acquired operating procedure data 108, and transmits the data to the display unit 205 (step S203). The operation procedure screen data is data for displaying an operation procedure for the user to operate the machine tool during setup. Next, the display unit 205 displays the operating procedure based on the received operating procedure screen data (step S204).

The machine tool operation acquisition unit 202 acquires NC change data that has changed due to the operation of the machine tool, and transmits the data to the second setting holding unit 203 (step S205). Here, the operation of the machine tool is the operation resulting from the user operating the machine tool according to the operation procedure displayed on the display unit 205 . Next, the numerical controller 200 performs machining (step S206).

In this manner, the operation procedure data creation unit 105 creates an operation procedure based on the changed setup machine tool motion data or the changed NC data so that the simulation apparatus 100 can reproduce the machine tool motion performed in the setup simulation. In general, a user tries a large number of setup operations, machining settings, and the like on a simulation, so it is difficult to grasp the operations of the machine tool during setup that are finally determined to be OK. However, according to the present embodiment, since the operation procedure is generated based on the changed setup machine tool operation data or the changed NC data that is judged to be OK by the judging section 113, the user can refer to the operation procedure to start the machine tool. It can be operated, and the possibility that the user will make a mistake in operating the machine tool during setup can be reduced.

Next, hardware that implements the simulation apparatus 100 according to the first embodiment will be described. The operation unit 110, the simulation execution unit 104, the operation procedure data creation unit 105, the first setting holding unit 107, and the first NC data transmission/reception unit 101 are implemented by processing circuits. This processing circuit may be a processor and memory that executes a program stored in the memory, or may be dedicated hardware. Processing circuitry is also called control circuitry.

FIG. 3 is a diagram showing a configuration example of a processing circuit provided in the simulation device 100 when the processing circuit is realized by an arithmetic device and a memory. FIG. 3 shows the configuration of hardware that implements the simulation apparatus 100 .

The simulation device 100 includes a computing device 501 that is a processor that performs computing processing, a memory 502 that the computing device 501 uses as a work area, a storage device 503 that stores programs and data, and communication that performs communication with the numerical control device 200. It has a device 504 , an input device 505 for receiving input from a user, and a display device 506 .

Examples of arithmetic unit 501 are a CPU (Central Processing Unit), a processing unit, a microprocessor, or a DSP (Digital Signal Processor). An example of memory 502 is a semiconductor memory. The storage device 503 is, for example, a non-volatile memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), EEPROM (registered trademark) (Electrically Erasable Programmable Read Only Memory). Or a volatile semiconductor memory, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD (Digital Versatile Disk), or the like.

The programs stored in the storage device 503 store procedures or methods executed by the operation unit 110 , the simulation execution unit 104 , the operation procedure data creation unit 105 , the first setting holding unit 107 , and the first NC data transmission/reception unit 101 to the arithmetic unit 501 . This is the program to run. That is, the functions of the operation unit 110, the simulation execution unit 104, the operation procedure data creation unit 105, the first setting holding unit 107, and the first NC data transmission/reception unit 101 are such that the arithmetic unit 501 executes the program stored in the storage unit 503. It is realized by

Examples of input device 505 are some or all of a keyboard, pointing device, and mouse. The display device 506 is means for confirming simulation results. An example of the display device 506 is a liquid crystal display. The input device 505 and the display device 506 may be integrated. Specifically, the input device 505 and the display device 506 may be realized by a touch panel.

Further, the processing circuit included in the simulation apparatus 100 may be configured with dedicated hardware. In this case, the processing circuit is, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof. It is.

Some of the functions of the operation unit 110, the simulation execution unit 104, the operation procedure data creation unit 105, the first setting holding unit 107, and the first NC data transmission/reception unit 101 are realized by software or firmware, The remainder of the functions may be implemented in dedicated hardware.

In this way, the multiple functions of the simulation execution unit 104, the operation procedure data creation unit 105, the first setting holding unit 107, and the first NC data transmission/reception unit 101 can be realized by hardware, software, firmware, or a combination thereof. can be done. Part of the operation unit 110, the simulation execution unit 104, the operation procedure data creation unit 105, the first setting holding unit 107, and the first NC data transmission/reception unit 101 may be implemented by separate processing circuits. Also, the operating procedure data creation unit 105 may be implemented on a server or cloud.

By following the operation procedure, the user operates the machine tool so as to obtain the result of the simulation performed by the simulation execution unit 104 and provides the machine tool operation acquisition unit 202 with NC change data. As a result, the desired machining result can be obtained because the setup can be performed according to the simulation. For example, safe machining that avoids interference can be achieved, and machining with excellent productivity can be achieved without redoing actual machining or reducing the number of times of actual machining.

Although an example in which the operating procedure data creation unit 105 is provided in the simulation device 100 has been shown, it may be provided in the numerical control device 200 . In that case, the simulation execution unit 104 may transmit the changed setup machine tool operation data or the changed NC data to the numerical controller 200 when the determination unit 113 determines that the machining is desired. Similar effects are obtained in this case as well.

Further, although the example in which the operation procedure screen creation unit 204 is provided in the numerical control device 200 has been described, it may be provided in the simulation device 100 . In that case, the simulation apparatus 100 may transmit the operation procedure screen data created by the operation procedure screen creating section to the numerical controller 200 . Similar effects are obtained in this case as well.

Also, although the NC data before the simulation is obtained from the numerical controller 200, the user may input it. Even in that case, the same effect can be obtained. Input errors can be eliminated by obtaining from the numerical controller 200 .

Moreover, although an example in which the user determines whether or not the processing is desired in the determination unit 113, an alarm may be output if the pre-input conditions are not met. The simulation device 100 may be configured to determine whether or not a pre-input condition is met. Even in that case, the same effect can be obtained.

In addition, when the NC data is changed during the simulation, the NC data after the change is reflected in the first setting holding unit 107, but even if the NC data is changed during the simulation, The operation procedure data creation unit 105 may output the operation procedure without changing the NC data. For example, after the first machining such as rough machining is processed with NC data, the machine tool operation and machining state are simulated based on the changed set-up machine tool operation data obtained by changing the set-up machine tool operation data, and the changed NC data or An operation procedure may be created from the changed set-up machine tool motion data and displayed on the numerical controller 200 to perform the second machining such as precision machining. In this way, the operator can reproduce necessary data changes after the start of machining according to the operation procedure at an appropriate timing such as switching from rough machining to finishing machining.

Further, although an example in which the numerical control device 200 obtains the NC change data from the machine tool operation acquisition unit 202 as it is has been described, a machine tool that checks whether or not the same operation as the operation procedure displayed on the display unit 205 has been performed has been described. A mechanical operation check unit may be provided. The NC change data may be acquired only when the operation is the same as the operation procedure displayed on the display unit 205, and an alarm may be output, for example, when the operation different from the operation procedure is acquired. By doing so, it is possible to further reduce the operator's setup errors.

Embodiment 2.
FIG. 4 is a schematic diagram showing the numerical control system 10 according to the second embodiment. Descriptions of the same parts as in the first embodiment are omitted. A numerical control system 10 according to the second embodiment will be described with reference to FIG. Compared to the first embodiment, the simulation apparatus 100 does not have the operation procedure data creation unit 105, the operation data output unit 109 is added, and the numerical control unit 200 has a machine tool operation acquisition unit 202 and an operation procedure screen creation unit. 204, the point that the display unit 205 is absent, and the point that the action reflecting unit 207 is added.

In the second embodiment, the motion data output unit 109 stores data used for simulating the motion of the machine tool in the setup executed by the simulation execution unit 104 as the motion information 114 . Specifically, the changed setup machine tool motion data or the changed NC data generated by the data change unit 111 is saved as the motion information 114 . The data acquisition unit 206 of the numerical controller 200 receives the motion information 114 from the simulation device 100 and transmits it to the motion reflection unit 207 . The data acquisition unit 206 of Embodiment 2 is a motion data acquisition unit. The motion reflecting unit 207 actually controls the machine tool based on the motion information 114 .

FIG. 5 is a flowchart of processing of the numerical control system 10 according to the second embodiment. Descriptions of the same parts as in the first embodiment are omitted. Compared to the flowchart of the first embodiment, it differs in that step S110 and steps S202 to S205 are omitted and step S111, step S207 and step S208 are added. Step S111 is the operation of the simulation device 100, and steps S207 and S208 are the operations of the numerical controller 200. FIG.

In the second embodiment, when it is determined in step S109 that actual machining is to be performed, the motion data output unit 109 saves and outputs changed setup machine tool motion data or changed NC data as motion information 114 (step S111). After the second NC data transmission/reception unit 201 acquires the changed NC data in step S201, the data acquisition unit 206 of the numerical controller 200 acquires the motion information 114 and transmits it to the motion reflection unit 207 (step S207). Here, the order of operations in steps S201 and S207 is not limited to this, and may be reversed.

Next, the motion reflecting unit 207 controls the machine tool based on the motion information 114 and performs setup (step S208). That is, the motion reflection unit 207 reflects the changed setup machine tool motion data or the changed NC data in the control of the machine tool.

In the first embodiment, the numerical controller 200 shows the operation procedure so that the user can easily reproduce the operation of the machine tool at the time of setup performed by the simulation device 100 . In the second embodiment, the numerical control unit 200 acquires the changed setup machine tool motion data or the changed NC data generated by the data change unit 111 as the motion information 114, and the motion reflecting unit 207 reflects it in the control of the machine tool. , the user does not need to operate the machine tool during setup. As a result, it is possible to eliminate the user's trouble of operating the machine tool and operation errors. That is, it is possible to reliably execute processing similar to the processing result of the simulation apparatus 100 .

Although the motion information 114 is the changed setup machine tool motion data or the changed NC data, it may be the pre-change setup machine tool motion data. Any machine operation data will suffice. In this case as well, since the motion reflection unit 207 reflects the results in the control of the machine tool, it is unnecessary for the user to operate the machine tool at the time of setup, and machining similar to the machining result of the simulation device 100 can be reliably executed. can.

Further, as in Embodiment 1, it may have a configuration for displaying an operation procedure, and may further have the action data output unit 109 and the action reflection unit 207 of this embodiment. For example, among the operations of the machine tool during setup used in the simulation, operations that require complicated user operations are automatically reflected, and other operations are displayed according to operation procedures. In this case, the above-described effect is obtained for the part that is automatically reflected, and the same effect as in the first embodiment is obtained for the part that shows the operation procedure.

Embodiment 3.
FIG. 6 is a schematic configuration diagram showing the numerical control system 10 according to the third embodiment. The difference is that in addition to the configuration of the first embodiment or the configuration of the second embodiment, another numerical control device 300 and a tablet terminal 400 are added. Descriptions of the same parts as in the first and second embodiments are omitted.

The configuration of another numerical controller 300 is the same as that of the numerical controller 200 . The second NC data transmitting/receiving unit 201 of the numerical control device 200 of the third embodiment performs the processing of the second NC data transmitting/receiving unit 201 of the first or second embodiment, and also performs the processing of the third NC data transmission/reception of another numerical control device 300. The modified NC data is transmitted to the section 301 . A third NC data transmitting/receiving unit 301 of another numerical control device 300 receives changed NC data from the numerical control device 200, 3 is stored in the setting holding unit 303 .

In addition to the processing of the data acquisition unit 206 in the first or second embodiment, the data acquisition unit 206 of the numerical control device 200 of the third embodiment performs the processing of the operation information 114 or the operation procedure data by another numerical control device. 300 to the data acquisition unit 306 . The data acquisition unit 306 of another numerical control device 300 acquires the operation information 114 or the operation procedure data 108 from the numerical control device 200 in addition to the same processing as the data acquisition unit 206 in Embodiment 1 or Embodiment 2. .

Tablet terminal 400 also includes data acquisition unit 206, operation procedure screen creation unit 204, and display unit 205 similar to numerical control device 200 of the first embodiment. The data acquisition unit 206 of the tablet terminal 400 acquires the operation procedure data 108 from the simulation device 100 or the numerical control device 200 and displays the operation procedure on the display unit 205 of the tablet terminal 400 . Although the tablet terminal 400 is connected to the numerical controller 200 in this embodiment, it may be connected to another numerical controller 300 .

As a result, not only does the simulation apparatus 100 transmit the operation information 114 or the operation procedure data 108 for reproducing the operation of the machine tool during setup as simulated to the numerical controllers 200, but also the numerical controllers 200 operate with each other. Since the information 114 or the operation procedure data 108 can be transmitted, there is an effect that the operation procedure of the first embodiment can be set up as simulated, and the action reflection of the second embodiment makes it unnecessary to operate the machine tool during setup. In addition to the effect, there is an effect that efficient machining can be performed by a plurality of numerical controllers. In addition, since the operation procedure can be displayed not only on the numerical control device but also on the tablet terminal, for example, the machine tool can be operated while moving with the tablet terminal.
