(Prior Art) In recent years, in the field of various processing machines such as laser processing machines and punch press machines, automatic generation of NC data for processing the machines to a numerical value of $1J has come to be practiced.

Conventional automatic generation of NC data requires a scanning device that converts processing drawings into point cloud data that can be input into a computer, and a scanning device that converts the drawing information converted into point cloud data into vector data that can be processed graphically. C A D (Coa+
The processing conditions are added to the CAD-edited data to obtain NC data suitable for processing.

(Problem to be Solved by the Invention) However, in the conventional automatic generation of NC data as described above, the drawings and data for machining are edited using general-purpose CAD, so the equipment becomes large-scale and There were problems in that it was not easy to use and required a lot of effort and time to work.

In other words, when automatically generating NC data using a general-purpose CAD, the entire device must be constructed by connecting a scanner device, CAD, and a computer for generating NC data. Therefore, the operation method is difficult to understand and it is difficult to adapt it to processing machines.

For example, in general-purpose CAD, if you want to specify only one arc of circle C at the intersection of straight ML and circle C, how to enter the arc on one side at the intersection of straight line and circle C,
The way it comes out and the way the arc goes around is r+J r-J or "1""
0” symbol must be entered.

As shown in the figure, the auxiliary data 5A for laser processing is as follows:
A list of graphical data such as shapes for inputting the machining start point, bridge shapes for so-called micro-joints, and arrow shapes indicating the machining direction, as well as machining conditions and machining information for laser machining. There is data,
These auxiliary data 5A are stored in the ROM 5.

Therefore, if we now edit the processing drawing shown in Figure 4,
FIG. 5 shows the NC data creation process.

First, in step 501, a processing drawing is input using the scanning device 2, and point cloud data 19 is converted into vector data in step 502, and edited in step 503 to obtain positioning data for laser cutting.
