Abstract

A machine learning device (40) that learns control parameters for determining conditions for cutting and wiring a wire electrode (90) of a wire electrical discharge machining apparatus (10) comprises: a state observation unit (44) that observes log data indicating the state in which the wire electrode (90) is inserted into a wire-electrode (90) path, data calculated from the log data, and a control parameter as state variables; and a learning unit (45) that, in accordance with a training data set created on the basis of the state variables, learns a control parameter for raising an insertion rate, which is the success rate for insertion of the wire electrode (90).

Description

technical field [0001] The present invention relates to a machine learning device for learning control parameters of a wire supply device used in wire electrical discharge machining, a wire electrical discharge machining system, and a machine learning method. Background technique [0002] A wire electrical discharge machine processes a workpiece by inserting a wire electrode into a hole or a groove of the workpiece and connecting the wire electrodes to each other by discharging electricity from the wire electrode. The wire electrical discharge machine cuts off the wire electrode after machining is completed, inserts the wire electrode at the next machining start position, and performs wiring. Cutting and connection of the wire electrodes are performed by a wire supply device included in the wire electrical discharge machine. [0003] If the wire supply device catches the wire electrode on the insertion path of the wire electrode, the insertion of the wire electrode may fail...
