Abstract
A CNC method controls a plurality of paths with a single computerized numerical control apparatus. In the CNC method, an order (6) in which to execute part programs (5) for the respective paths (4) is designated, and the part programs (5) are sequentially executed in the designated order. The contents of the part programs (5) can thus be checked for each of the part programs.
Claims2
A CNC method of controlling a plurality of paths machined by a multi-head numerical control engine lathe, using a single computerized numerical control apparatus, said method comprising the steps of:
- (a) storing a plurality of part programs, corresponding to the plurality of paths, for parallel execution by the single computerized numerical control apparatus;
- (b) designating on a display screen an order in which to execute the path programs for respective paths;
- (c) sequentially executing the part programs for the respective paths in the order designated in step (b);
- (d) checking the part programs in dependence upon said executing in step (c);
- (e) correcting any errors in the part programs detected during said checking in step (d);
- and
- (f) machining a workpiece by parallel execution of the part programs after performing steps (a)-(e).
