Description

A system of the instruction for the control of CNC and method

The present invention relates to a CNC machine training system, a control method thereof, and a recording medium for teaching a computer to operate a Numerical Control (NC) machine system in a real order and method using a computer. CNC machine training system to provide courses and textbooks, and to process the content posted on the textbook in real time through the simulator to check its shape, and to identify problems and to maximize the effectiveness of the training. It relates to a control method and a recording medium.

In general, Numerical Control (NC) machine system means that the controller analyzes the NC code input from the outside and then transmits the movement signal of each coordinate axis to the machine according to the result of analysis. Move along to process the workpiece into the desired shape, or after the controller analyzes the NC code directly written by the controller, and transmits the movement signal of each coordinate axis according to the analyzed result to the machine, Refers to an apparatus that moves to process a workpiece into a desired shape.

The user of such an NC machine system needs to fully master the operation method so that the NC machine system can be used skillfully in order to prevent damage to the NC machine system and the danger that may occur when the NC machine system is actually operated.

As a tool for learning the operating method of the NC machining system, a program manipulator is used as hardware, and a CNC simulator is used as software.

The program manipulator is a device that separates only the controller part from the NC machine, and can learn most of the controller functions such as manual NC code creation and machine panel operation. However, even if the controller is executed, it is not connected to the actual machine. The machine operation such as the movement of the tool cannot be seen, and the inspection of overcut and uncut after machining the workpiece by the actual NC machine is also impossible.

In addition, the CNC simulator can create a NC code and perform simulation by setting various processing conditions and verify the workpiece after processing. It is not only difficult to learn how to use the controller by the method, but the shape of the workpiece is displayed on the screen, but there is a problem that the reaction of the machine according to the machine operation command such as tool movement by NC code and the machining of the workpiece until then are not seen. .

In addition, as a technique devised to solve the problems of the prior art, there was a "virtual computer numerical control system and method" of "Patent No. 182393".

The virtual CNC machine system comprises an input means for reading an NC code, a central processing means for reading an NC code from the input means or a storage means, and generating a tool movement signal, and a signal from the central processing means. Machine display means for showing the movement of the tool and the machining of the workpiece in real time, verification display means for indicating the final machining state of the workpiece by signals from the central processing means, and data required by the central processing means. And a storage means for storing, the central processing means, the machine display means, and a means for controlling the verification display means to operate independently and simultaneously.

The virtual CNC machining method includes reading an NC code from an input means or a storage means, reading an NC code from the input means or a storage means, and generating a tool movement signal from a central processing means; Indicating the movement of the machine and the tool and the machining of the workpiece by the signal from the processing means in real time on the machine display means, and the final machining of the workpiece by the signal from the central processing means in the verification display means. And giving the central processing means, the machine display means, and the verification display means independently and simultaneously.

However, the prior art is not composed of a textbook that can guide the operation process, there is a problem that can not be maximized in the educational effect.

In addition, the prior art shows a precise final machining result in a separate window in real time with the movement of the machine, even if only the results of the machining, or the simulation of the machine is shown without the simulation of the machine for display speed There was a problem that can not show the precise machining results.

Therefore, by using the controller necessary for the actual CNC operation, the movement of the machine as a result of the operation, and the shape of the material as the result of the machining, the CNC machine training system and the control method of the CNC machine can be maximized. Development has been required,

Unlike the prior art, by verifying not only the geometric result of machining but also the method of processing, it is easy to recognize the correlation between the code used and the result, and the educational effect of learning how to use the G code, which is a CNC operation code, is large. There has been a demand for the development of a CNC machine training system, its control method, to facilitate modifications,

It provides a systematic training process and textbooks, and processes the contents posted on the textbooks in real time through a simulator so that the shape can be checked at the same time, and the problem can be checked. Development of the method has been required.

The present invention was devised to meet the above demands, and provides a systematic curriculum and teaching materials as well as learning machine tools through simulation in a virtual space, and provides real-time contents of the teaching materials through a simulator. It is an object of the present invention to provide a CNC machine training system, a control method thereof, and a recording medium which can maximize the educational effect by allowing the machine to check its shape.

A computer readable recording medium having recorded thereon a program for executing a third step of changing a machine state and a workpiece processing state and a screen display is provided.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a CNC machine training system, a control method and a recording medium according to the present invention will be described in detail.

In the drawings, Figure 1 is a block diagram of a CNC machine training system according to an embodiment of the present invention.

As shown in the figure, the CNC work education system according to an embodiment of the present invention, the input means 110, teaching materials processing means 120, signal control means 130, central processing means 140, storage means 150 and display means 160 are provided.

The input means 111 includes a direct input means 111 and a virtual input means 112.

In addition, the teaching material processing unit 120 includes a teaching material display unit 121, a teaching command unit 122, a communication unit 123, and a teaching material control unit 124.

The central processing unit 140 includes a controller unit 141 and a machine unit 142.

In addition, the display means 160 is composed of a controller display unit 161 for displaying the controller state as a CRT screen of the manipulator, and a machine display unit 162 for showing the operation state of the current machine and the processing state of the work.

Now, look at in detail the operation of the CNC machine training system according to an embodiment of the present invention.

First, the direct input unit 111 of the input unit 110 receives a signal from the outside, and if the input signal is a teaching material related processing signal, outputs it to the teaching material display unit 121 of the teaching material processing unit 120, and the input signal is If the NC code is output to the signal control means 130, if the input signal is a virtual input control signal is output to the virtual input unit 112. Here, the direct input unit 111 may be a keyboard, a mouse, and the like.

In this case, the user may input the preparation command signal of the tool and the workpiece, the tool preparation signal, and the like into the signal control means 130 through the direct input unit 111.

In addition, the virtual input unit 112 is implemented so that the user can see the appearance of the actual manipulator on the screen, and the user inputs letters and numbers by buttons like the actual manipulator through the input unit 111 directly while viewing the screen. Alternatively, MPG (Manual Pulse Generator), rotation, toggle switch operation can be performed.

Therefore, the virtual input unit 112 of the input unit 110 converts an operation panel such as a button that exists virtually in accordance with the input virtual input control signal, and then the central processing unit 140 displays the NC code indicated by the operation panel. The controller unit 141 transmits the data.

In this case, various auxiliary devices such as the preparation process of the tool and the work, the magazine and the turret of the tool may also be controlled through the operation panel of the virtual input unit 112 of the input unit 110.

Then, after the textbook display unit 121 of the textbook processing unit 120 displays the embedded textbook on the screen, if the NC code is directly input from the input unit 111, the textbook is displayed on the screen. The NC code execution request signal is transmitted to the command unit 122.

The textbook display unit 121 composes the basic contents of the textbook using HTML (Hyper Text Mark-up language) and uses Explorer Active X control.

It consists of text, tables, still pictures, and animated GIFs.

The textbook display unit 121 provides a curriculum and a textbook for systematically learning an actual CNC machine tool. In addition, it provides you with exercises and step-by-step examples to help you practice the NC code you learned.

These exercises can be simulated to show the results of the machined geometry in real time, as the learner enters code and just pushes a button in the textbook.

The answer can also be found by comparing the path differences by machining simulation separately from the input by the learner.

When the NC code execution request signal is input from the textbook display unit 121, the textbook command unit 122 receives an input signal such as an NC code input from the textbook display unit 121 through the direct input unit 111 of the input unit 110. After the reading, the command execution request signal incorporating the command for providing a stable environment during processing to the read signal is transmitted to the teaching material control unit 124 through the communication unit 123.

At this time, a command for providing a stable environment during machining includes a material generation command, an origin setting command, a tool preparation command, and the like.

The communication unit 123 is provided as "Active X control" (hereinafter referred to as OCX), and serves to transmit a command to the textbook control unit 124.

The reason why the communication unit 123 should be separate is that the text display unit 121 is actually a web browser, which does not provide a means for communicating with a specific application.

Therefore, a separate communication means is required to transmit the command of the teaching material command part 122 to the teaching material control part 124. In the CNC machine education system, the communication part 123 of the OCX control type is provided.

The teaching material control unit 124 sends a stop request signal to the signal control unit 130 when the instruction execution request signal including the NC code is input from the teaching material command unit 122, and then the machine unit 142 is in a waiting state. Wait until

At this time, the command sent from the communication unit 123 is stored in the command QUEUE.

When the mechanical unit 142 is in the standby state, the teaching material control unit 142 transmits the contents of the stored command QUEUE to the signal control unit 130.

On the other hand, when the command including the NC code is directly input from the input unit 111 or the teaching material control unit 124, the signal control unit 130 checks the execution state of the current central processing unit 140.

When the controller 141 or the mechanical unit 142 of the central processing unit 140 is in the running state, the signal input directly from the input unit 111 is temporarily stored and placed in a standby state. If the signal is input from 124, the instruction execution control signal is transmitted to the textbook controller 124 to wait for the command transmission.

As a result of the inspection, if the controller unit 141 or the machine unit 142 of the central processing unit 140 is not running, the signal input from the input unit 111 or the textbook controller 124 is directly output to the controller unit 141. do.

Then, the controller unit 141 of the central processing unit 140 sequentially analyzes the input NC code when the command signal including the NC code input from the virtual input unit 112 and the signal control unit 130 is input. And create a list of commands corresponding to the parsed code.

At this time, the controller unit 141 of the central processing unit 140 stores the input NC code file in the storage unit 150 when the input signal is a NC code file.

The controller unit 141 of the central processing unit 140 sequentially reads and interprets the NC code stored from the storage unit 150 to create a command list.

The controller unit 141 of the central processing unit 140 executes a command according to the command list, changes the controller state and the machine state, and then transfers and stores the changed controller state to the storage unit 150, and the machine unit Informs 142 that the current machine state has changed.

At this time, the controller unit 141 of the central processing unit 140 reads out data necessary for executing the command from the storage unit 150 and processes the command.

Then, the machine unit 142 changes the machine state by using the information stored from the memory means 150, processes the workpiece by the changed machine position information and the tool information, and stores the changed machine state and the workpiece processing process into the storage means ( 150).

At this time, in order to process the material and store it in the storage means 150, the three-dimensional milling machine updates the material processing state in real time by updating the Z value by the tool movement trajectory volume difference using the Z-Map data. In the two-dimensional lathe machine, the workpiece processing state is stored in the storage means 150 using a two-dimensional polygon that is a result of a two-dimensional difference boolean operation between the movement trajectory cross section and the workpiece cross section of the lathe tool. . In addition, by storing the methods used in the machining, you can easily check the contents of the code learned when verifying the workpiece later.

After the controller unit 141 of the central processing unit 140 performs the command of the command list, the controller unit 141 transmits a display command signal to the controller display unit 161, which causes the controller display unit 161 to transmit to the storage unit 150. The saved controller status is displayed on the screen.

In addition, the machine unit 142 of the central processing unit 140 transmits a display command signal to the machine display unit 162 after executing a command according to the command list, thereby causing the machine display unit 162 to change the state of the machine. The cutting state of the workpiece is displayed on the screen.

At this time, the controller display unit 161 displays the contents of the NC code, the position information of the current machine, the tool information, the G code, the address value, the coordinate system, and the like on the screen using the information stored in the storage means 150. Can be.

The machine display unit 162 displays the operation state of the machine and the state of the material processed on the machine by the three-dimensional graphic library and the storage means 150 in real time, and to describe the processing state of the material, as described above, In the dimensional milling machine, Z-map is used, and in the two-dimensional lathe machine, two-dimensional drawing of section rotation is used.

The storage means 150 is a three-dimensional graphic library for displaying data on XYZ coordinate values to be moved according to the NC code input from the input means 110, pre-written NC codes, movements of machines and tools, and machining of workpieces. For example, the data required by the mechanical unit 142 is stored, including OpenGL).

On the other hand, the above operation is repeatedly performed until all instructions interpreted from the NC code are executed.

In the drawing, the teaching material processing means 220 has two threads, one of which is a teaching material display unit 221 thread that interprets and displays html teaching material contents on a teaching material screen, and the other teaching material command generates an instruction by receiving an external signal. It is a thread composed of a generation unit 222 module and a communication unit 223 module to transmit.

Then, the signal control means 230 drives the required thread by determining the type of the signal input from the input means 210, and outputs the signal input from the textbook processing means 220 to the controller means 240. .

The controller means 240 is composed of an NC code storage unit 241 module, a code analysis unit 242 module and a display unit 243 module.

The code analysis unit 242 analyzes coordinate values to be moved in the selected NC code and stores them in the storage means. The display unit 243 serves to display the position of the converted coordinates on the screen.

The mechanical means 250 is comprised from the machine moving part 251 module, the processing part 252 module, and the display part 253 module.

When the mechanical means 250 starts to operate, the machine moving part 251 is driven first.

If the code interpreted by the code analyzing unit 242 of the controller unit 240 is in the storage unit, the machine moving unit 251 reads it to move the machine and drives the processing unit 252.

The processing unit 252 drives the display unit 253 after receiving the movement signal and processing the material by two-dimensional figure or Z-map difference calculation.

The display unit 253 displays the movement of the machine and the processed shape on the screen.

Each thread wakes up when it receives the signal it needs, otherwise it is idle.

On the other hand, as a result of the determination, it is determined whether or not the teaching material input signal is a machine setting signal. If it is a machine setting signal, the controller means and the machine means are set to the standby state in step S19, and after changing the machine setting in step S20, in step S21 Wait for input of external signal.

On the other hand, as a result of the determination, if it is not the machine setting signal, it is determined whether it is the controller signal in step S22, and if it is not the controller signal, the controller waits for input of an external signal in step S23, and if it is the controller signal, sets the controller means to the running state in step S24, In step S25, the NC code is transmitted to the controller means.

Subsequently, it is determined whether the controller is in the running state in step S26, and if it is not in the running state of the controller, the standby state is in step S27. If the controller is in the running state, the NC code is interpreted in step S28 to display the state of the controller in step S29. It is determined whether there is an NC code interpreted in step S30.

As a result of the determination, if there is no interpreted NC code, it is set to the machine standby state in step S31, and after setting to the machine execution state in step S32, it is determined in step S33 whether the machine is in the running state.
