Abstract
A machining process sequence defined by machining definition steps is displayed on a display screen in the form of a flowchart (FLC). In subsequently performed processing for automatically deciding a machining process sequence, the machining process sequence is revised in such a manner that machining processes (e.g. 01/01. 02/01, 03/01), the order of which must not be changed, are arranged in a serial machining sequence and machining processes (e.g. 02/01, 02/02, 02/03, 02/04, 02/05), the order of which may be changed, are arranged in parallel. NC data are created on the basis of the revised machining process sequence.
Claims7
A method of creating numerical control data for machining a blank into a desired shape through a plurality of machining processes, comprising the steps of:
- (a) inputting machining process data, including type of machining to be performed on the blank to produce the desired shape, in an input order;
- (b) displaying on a display screen a flowchart illustrating the machining process data from step (a) in a machining process sequence serially according to the input order;
- (c) revising the machining process sequence displayed in the flowchart in response to one of (i) designating a first machining process at an origin of movement and a destination of movement for the first machining process and (ii) designating a second machining process which is an object of a serial/parallel rearrangement;
- and
- (d) displaying a revised flowchart illustrating a revised machining process sequence in dependence upon said revising in step (c);
- and
- (e) creating numerical control data, based on the revised machining process sequence, to perform machining of the blank with the machining processes in any serial portions of the revised machining process sequence to be executed serially and the machining processes in any parallel portions of the revised machining process sequence to be executed without regard to the input order.
