NC DATA GENERATING SYSTEM FOR WORKING OF PART LEFT UNCUT IN NC DATA ORIGINATING DEVICE

摘要

PURPOSE:To reduce the number of processes, by generating an NC data for working a part left uncut by means of calculation automatically, after the part left uncut generated in a two-dimensional contour working by an NC data originating device is stored. CONSTITUTION:When the part left uncut is generated after interference check at a tool interference check part 5, a part left uncut reference line is calculated at a part left uncut reference line arithmetic part 9 based on the information SR of the part left uncut, and the information SP of a process reference line from a working reference line storage part 3. And the data is stored in a part left uncut reference line storage part 10, and also, it is graphic-displayed on a CRT14 via a part left uncut display part 12. One part of part left uncut reference line in the part left uncut reference line storage part 10 is stored in the working reference line storage part 3 via a reference line take out part 11, and it is used as the process reference line to work the part left uncut.
