Abstract
Abstract An NC program drawing method for an interactive numerical control device is provided, in which an NC program is represented by a composite drawing composed of a solid drawing (1a, 1b, 1c) and a wire frame drawing (1d, 1e), whereby the drawing of machining profiles and tool paths, etc., can be processed in a short time and the machining profiles can be easily recognized, thus facilitating the creation of machining programs. According to a preferred mode of carrying out the invention, simple surfaces and the like are drawn by the solid drawing method (1a, 1b, 1c), and complicated profiles (1d, 1e) and tool paths, etc., are drawn by the wire frame drawing method.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
59 words
An NC program drawing method for an interactive numerical control device including a display device, comprising the steps of: (a) representing a composite drawing using a solid drawing and a wire frame drawing; (b) displaying the composite drawing on the display device; and (c) automatically creating a machining program based on the solid drawing and the wire frame drawing.
Claim 2
Dependent Claim
59 words
An NC program drawing method for an interactive numerical control device including a display device, comprising the steps of: (a) representing a composite drawing using a solid drawing and a wire frame drawing; (b) displaying the composite drawing on the display device; and (c) automatically creating a machining program based on the solid drawing and the wire frame drawing.
Claim 3
Dependent Claim
50 words
An NC program drawing method according to claim 1, further comprising the step of: (d) determining whether the NC program should be represented by one of the solid drawing, the wire frame drawing, and the composite drawing in accordance with types of profiles or processes instructed by the NC program.
Claim 4
Dependent Claim
44 words
An NC program drawing method according to claim 1, wherein step (b) includes the substep of: (b1) drawing the composite drawing by using the solid drawing to represent simple surfaces and by using the wire frame drawing to represent complicated profiles and tool paths.
