Field: Machine tools (Mechanical engineering)
Classification: CPC G  B  Y | IPC B  G

Claim 5:
6. A program editing device for editing a machining program in which a machining path along which a wire electrode of a wire electrical discharge machine machines a workpiece is defined,
wherein the machining program includes a plurality of blocks corresponding to respective multiple partial paths into which the machining path is divided, each of the blocks including path information indicating the corresponding partial path,
the program editing device, comprising:
an analyzer configured to analyze the machining program and thereby identify a predetermined shape pattern formed by a series of the multiple partial paths in the machining path;
an information generator configured to generate shape information corresponding to the identified predetermined shape pattern; and
an editor configured to insert the shape information into the machining program wherein:
the predetermined shape pattern includes a pseudo-curve shape formed of a series of straight linear paths; and
the shape information corresponding to the pseudo-curve shape includes information indicating a curve shape that approximates to the pseudo-curve shape.
