Therefore, even in the case of confirming the operating state by simulating a program created to prevent the above problems, conventionally, it is not possible to check the machining state processed by the operation of the program step by step. As can be confirmed, a problem arises in that it is impossible to make an accurate determination of whether a workpiece of a desired state can be produced by the operation of a normal program.

Therefore, in order to check the operation status of the correct program, it is necessary to actually operate the NC machine.

Figure 2 is an N. C. in accordance with an embodiment of the present invention. Is a flow chart of the simulation method of the program,

3A to 3C are N.C. This is the output state of the computer monitor according to the operation of the program.

Referring to Fig. 1, the configuration of the present invention will be described. An input unit 11 for inputting a control command capable of controlling the operation of desired data or program, and NC. A program is built in, and the corresponding operation is executed according to data or control commands inputted through the input unit 11. An operation control unit 12 for operating the machine and outputting a simulation state, and a workpiece connected to the operation control unit 12 to be processed according to the operation of the operation control unit 12 and outputting a simulation process according to each selected condition. It consists of a computer monitor (13).

The operation of the present invention made as described above will be described with reference to Figs.

First, when the power required for the operation of each device is supplied, it is developed. The operation of the operation control unit 12 is performed by a program to simulate the processing state of the workpiece through the data output unit 13.

When the operation of the operation control unit 12 starts (S10), as shown in FIG. 3A, an initial screen is output through the computer monitor 13.

Therefore, the user selects each desired output condition from the initial screen output through the computer monitor 13 so as to execute a desired simulation operation.

Therefore, the user inputs the name of the work file so that the user can select the work file for the simulation operation (S11), and checks the input work file to select the corresponding work file (S12, S13).

When a job file to execute the simulation operation is selected as described above, the operation control unit 12 uses an input unit 11 such as a mouse or a keyboard to execute a simulation of an operation for processing a workpiece under a desired condition. Select each desired condition.

Therefore, the operation control unit 12 is stored in the memory of the current operation control unit 12 by the user. The display mode for executing the simulation operation of the workpiece by using the computer monitor 13 by the operation of the program is selected, or NC. It is determined whether an edit mode for modifying a program is selected (S14).

Therefore, when the operation mode selected by the user through the input unit 11 is an output mode, the operation control unit 12 determines whether a multi-array mode (material mode) for simulating the machining operation state of the workpiece to be processed is selected, or the workpiece Processing status as well as N.C. N.C. operated by the program. It is determined whether an all mode capable of simulating the operating state of the machine is selected (S15).

When one of the desired modes is selected by the user from the material mode and the all mode, the user can enter the NC through the input unit 11. Select and enter the operating speed of the machine (S16).

In order to output the simulation operation through the computer monitor 13 at a desired angle, the user selects a desired output form using the input unit 11 (S17).

That is, as shown in Fig. 3, TOP is selected for a plan view, FRONT is selected for a front view, and ISO is selected for a perspective view.

When both the object to be output, the processing speed, and the output form are selected by the user, the operation controller 12 executes a corresponding operation according to each mode selected, and the (b) and (c) of FIG. The simulating process is output through the computer monitor 13 in the same state.

Therefore, the user can determine whether the machining operation currently being processed is being executed in a normal state by using the simulation operation output through the computer monitor 13.

In addition, since the processing speed of the workpiece can be arbitrarily selected, the state of each machining process can be judged to easily determine the position of error occurrence. It is easy to modify the program.

However, if the machining operation state of the workpiece is not the desired state, the user may The program must be modified to achieve the desired machining behavior.

Therefore, the user selects the operation mode of the operation controller 12 as the edit mode in step S14.

When the operation mode of the operation control unit 12 is the edit mode by the user, the operation control unit 12 outputs the menu screen of the editing mode (not shown) through the computer monitor 13 (S19).

And by user. Allows editing of the corresponding part of the program (S20).

N. When the editing operation of the program is completed, it is edited according to the operation of the input unit 11 by the user. After storing the program (S21), the operation of the edit mode is terminated (S22).

Therefore, the newly revised N.C. Depending on the operation of the program, it is possible to re-execute the simulation operation of the workpiece.

Therefore, the effect of the present invention operating as described above is N.C. N.C. controls the behavior of the machine to achieve the desired workpiece. N.C. was developed because the computer's operating state can be simulated on a computer using computer graphics. The operating state of the program can be easily predicted.

Also N. The machining state of the workpiece simulated by the program's motion can be checked from different angles. Accurately determine the operating status of the program.

The user can select and operate the simulated motion speed arbitrarily. Therefore, the accurate machining status can be judged by the processing stage of the workpiece. The error occurrence part of the program can be judged easily and accurately.

And the correct NC can be judged accurately without operating the NC machine. N.C. by program It can prevent the huge economic loss caused by the machine malfunction.
