Abstract
A prompt (MEQ) which indicates whether a machining end-point is (i) a point which coincides with a machining starting point, (ii) a point a predetermined amount .DELTA..alpha. past the machining starting point, or (iii) a point a predetermined amount .DELTA..alpha. short of the machining starting point is included on a dialog screen (DIM) and machining end-point information is entered from a keyboard (12). In response, a processor (11a) of a system main body (11) automatically computes coordinates of the machining from the machining end-point information, the machining starting point and path data, and creates NC data for arriving at the machining end-point along a path specified by the path data.

An NC data creation method for automatically creating NC data for wire-cut electrical discharge machining, comprising the steps of:
- (a) presetting a predetermined amount;
- (b) entering machining end-point information indicating that a machining end-point is one of a point which coincides with a machining starting point, a point causing machining to continue the predetermined amount past the machining starting point, and a point causing machining to stop the predetermined amount short of the machining starting point;
- (c) centering coordinates of the machining starting point;
- (d) entering path data for specifying a part profile;
- (e) computing coordinates of the machining end-point from the machining end-point information, the machining starting point and the path data;
- and
- (f) creating the NC data for arriving at the machining end-point along a substantially closed loop path specified by the path data.
A method for automatically creating numerical control data for machining an object, the numerical control data being associated with a machining start point, path data and a machining end point, said method comprising the steps of:
- (a) inputting machining start point coordinates, machining end point information and the path data;
- (b) computing coordinates of the machining end point based on the machining end point information, the machining start point coordinates, and the path data;
- and
- (c) creating the numerical control data for machining the object from the machining start point along a substantially closed loop path designated by the path data to the machining end point.
A system for automatically creating numerical control data for machining an object, the numerical control data associated with a machining start point, path data and a machining end point, said system comprising:
- memory storage means for storing at least a predetermined distance representing a distance between the machining start point and the machining end point;
- input means for inputting machining start point coordinates, machining end point information and the path data;
- and
- processing means for controlling creation of the numerical control data, said processing means including
- means for computing coordinates of the machining end point based on the machining end point information, the machining start point coordinates, the predetermined distance, and the path data;
- and
- means for creating the numerical control data for machining the object from the machining start point along a substantially closed loop path designated by the path data to the machining end point.
