Abstract

A control unit for executing a control method for controlling a wire electrical discharge machine includes a machining control unit for carrying out first machining on a first machining object, suspending the first machining if an interruption is necessary, carrying out second machining on a second machining object, and resuming the first machining after the second machining ends; a timing unit for timing a first period from the start to the suspension of the first machining, and a second period from the resumption to the end of the first machining; and a machining time calculation unit for calculating a first total time required for the first machining.

Claims20

Dependent claims

A control device configured to control a wire electric discharge machine, the control device comprising:

a machining control unit configured to:
control the wire electric discharge machine to thereby carry out a first machining on a first workpiece;
and in a case that an interruption request is made during the first machining, control the wire electric discharge machine to thereby interrupt the first machining, carry out a second machining on a second workpiece that differs from the first workpiece, and resume the first machining after the second machining has been completed;
a time measurement unit configured to measure a first time period that has been required for the first machining from starting of the first machining until interruption of the first machining, and a second time period that has been required for the first machining from resuming of the first machining until ending of the first machining;
and
a machining time calculation unit configured to calculate, using the first time period and the second time period, a first total time period that has been required for the first machining.
