Wire electrical discharge machine and wire electrical discharge machining method

A wire electrical discharge machine for performing electrical discharge machining on a workpiece by applying voltage to a discharge gap between a wire electrode and the workpiece to generate electrical discharge while causing the wire electrode and the workpiece to move relative to each other, comprising:

• a processor;
• and
• a memory, the processor running a program stored in the memory to control:
• an electrical discharge machining control unit configured to perform electrical discharge machining by applying voltage to the discharge gap while moving the wire electrode relative to the workpiece according to a machining program and a machining condition;
• an approach section identifying unit configured to identify an approach section in a machining path for the wire electrode with respect to the workpiece, based on the machining program;
• and
• an adjustment unit configured to adjust the machining condition based on a preset adjustment ratio,
• wherein the electrical discharge machining control unit is configured to perform electrical discharge machining control in the approach section, using the adjusted machining condition.
