Abstract

A controller (12) for a wire electrical discharge machine (10) that machines a workpiece (W) along a machining path (R) by relatively moving the workpiece (W) and a wire electrode (14) to each other while generating electric discharge across an electrode gap between the workpiece (W) and the wire electrode (14), includes: a machining surface state acquisition unit (30) configured to acquire the state of a machining surface (Wf) of the workpiece (W); and a machining path setting unit (32) configured to specify an excessively machined portion (Co) of the workpiece (W) based on the acquired state of the machining surface (Wf) and set an approach point (A) at which the wire electrode (14) is made to approach the machining surface (Wf) from a machining start point (S), so as to avoid the excessively machined portion (Co).
