to be transmitted. In step S, the area determining means 2 determines whether the generated axis movement data is within the specified area.
2) If the axis movement data is within the specified area, it is manually stored in the movement path storage means 3 (step S
3) The read movement route is manually input to the closed loop 8 movement route deletion means 4, and if there is a closed loop, it is deleted (step S4). In the example shown in FIGS. 3 and 4, the route from movement route b to c is within the designated area, and the movement X, Y route jQ means 3 has a The travel route is stored as data.

For example, when the evacuation external signal is manually inputted at point h in Fig. 4, the evacuation/axis movement data at points h-g-f-b are manually inputted to Axis movement data generation means 5
If a rotational external signal is input after that, re-entrance axis movement data for points b-fgh-h is generated in the same way (step 57). The axis movement data selection means 6 selects the axis movement data based on a normal numerical control program when there is no external signal (step S6), and selects the axis movement data based on the generated evacuation/reentry when there is the above-mentioned evacuation or ancient external signal. Select the axis movement data (step S8) and send it to the axis movement control means 7 to control the axis movement.
