Displayed virtually, it is easier to determine errors in the encoder code, malfunction of the tool of the machine tool, and the machining of the raw materials.

On the other hand, as shown in Figure 3 is a block diagram showing another embodiment of the present invention, the present invention will be described as follows.

The direct control method of this SINCHEN machine tool is a three-dimensional display step (S1) and a three-dimensional display step of the tool to display the tool and the material on the monitor of the personal computer connected to the machine tool and to draw on the virtual material directly (S2) and a direct drawing step (S3), an encicode generation step (S4) for generating an encoding code according to the tool and the material from the shape designed on the virtual material,

The tool movement simulation step (S41) and the workpiece processing simulation step (S42), which simulate the movement of the tool and the machining state of the workpiece before transferring the generated encoder to the machine tool, and after the simulation is completed, the encoder is transferred to the machine tool.

Here, the tool movement simulation step (S41) is to transmit the encicode to the machine tool to simulate the movement state of the tool in advance before the material is actually processed, so that the error of the encicode can be easily determined in real time.

In addition, the material processing simulation step (S42) refers to the step to simulate the virtual processing of the material set on the monitor in accordance with the trajectory of the virtually displayed tool.

On the monitor of the personal computer connected in series with the SINC machine tool while the SINC machine tool is operated and initialized, the tools and the workbench of the SI machine tool are set at a ratio that matches the actual size. The display is displayed in three dimensions, and a virtual material is set at a ratio that matches the actual size of the material on the upper surface of the work table thus displayed (S10).

In this way, the user draws a shape directly on the upper surface of the material displayed on the screen of the monitor using a user input device such as a mouse (S11).

After completing the direct drawing by the user, when the command for generating an encoder is generated, the computer automatically generates an encoder from a tool, a material, and a shape to be processed according to a virtual ratio (S12).

Then, the user selects whether or not to simulate the movement path of the tool and the machining of the material using the generated encicode (S13).

At this time, if the user does not select execution of the simulation, the generated encicode is immediately transmitted to the machine tool (S14), and the machining data is extracted from the transmitted encicode to process the material (S15).

On the other hand, when the user selects the execution of the simulation, the generated movement code and the machining state of the material are virtually output on the screen using the generated encicode (S20). It is determined whether or not (S21).

In this case, when the user selects the drawing again, the process returns to step S11 of drawing by direct input and the drawing is performed.

When the user does not select the drawing again, the generated encicode is transmitted to the machine tool (S14), and the transmitted encicode extracts processing data by the machine tool to process the material (S15).

While the material is actually being processed by the material processing step (S15), the movement path of the tool is detected through a detector provided in the machine tool itself, and the detected data is transmitted to the computer in real time, and the computer is transmitted through the transmitted data. While outputting the movement state of the tool on the monitor screen at the same time, the virtual workpiece is deleted according to the progress trajectory of the tool to output the machining state of the workpiece on the screen (S16).

It is determined whether the movement state of the tool and the machining state of the raw material are added to the actually processed shape after the output is completed on the screen of the monitor to be processed (S17).

If the user does not choose to process additionally, the process is terminated. If the user chooses to process additionally, the process returns to the drawing step (S11) by direct input, and the machining is virtually performed again on the material displayed on the screen of the monitor. In addition, by drawing a further processing will be done.

In this way, it is easy to sequentially process a complex shape as a series of additional processing to the actual processed material.

At this time, the virtual workbench and the tool has a separate coordinate system and the position selection is free.

In addition, as shown in FIG. 6, after setting the material at a rate that matches the actual size on the monitor of the computer connected to the machine tool, the user can see the state displayed in three dimensions, and the user is in a state where the material is virtually set. You can see the state of the shape to be directly processed.

In addition, as shown in FIG. 7, after the direct drawing by the user is finished on the virtual material, the state of generating an encoder according to the virtual tool and the material and the shape to be processed can be seen.
