<p>PURPOSE:To specify a cut direction or the like easily by displaying a track of passage on a cathode-ray tube and indicating positions of passage on the start point side and the end point side with cursor blink and inputting the cut direction. CONSTITUTION:Passage data is read out from a memory 101 by a processor 103 and is stored in an RAM106, and this data is subjected to the interpolating operation in a vector generator 105a and is inputted to an address counter 105b and is allowed to pass a screen memory 105c to display tracks of passage P1- P16 on a cathode-ray tube 105d. A cursor is displayed on the cathode-ray tube, and points P are indicated by this cursor, and NC data for passages where cutting is advanced from the end point side or the start point side to the start point side or the end poit side is generated by a cursor display position switching key, a cut direction input key, etc. on an operation panel 102. The processor 103 indicates the start point-side passage position P2 with the cursor when the cursor is reset by depression of said switching key, and the processor 103 indicates the end point-side passage position P16 when it is set.</p> |
