Abstract
A wire electrical discharge machine includes: a drive control unit for moving a wire electrode relative to a workpiece along a machining path; a path determination unit for determining whether or not the machining path includes a linear path section that crosses a boundary line between a thick portion and a thin portion of the workpiece; and a path compensator for compensating the machining path so as to form, in the thin portion, a protrusion projecting outward from the boundary line when the path determination unit determines that the linear path section is included.
Claims14
A wire electrical discharge machine that machines a workpiece using a wire electrode, the wire electrical discharge machine comprising:
- a drive control unit configured to move the wire electrode relative to the workpiece along a machining path set in a machining program;
- a path determination unit configured to determine whether or not the machining path includes a linear path section that crosses a boundary line between a thick portion of the workpiece and a thin portion of the workpiece, a thickness of the thin portion being smaller than a thickness of the thick portion in an extending direction of the wire electrode;
- and
- a path compensator configured to compensate the machining path so as to form, in the thin portion over a predetermined distance, a protrusion projecting outward from the boundary line when the path determination unit determines that the linear path section is included.
A machining program editor that edits a machining program in which a machining path for a wire electrode of a wire electrical discharge machine is set, the machining program editor comprising:
- a path determination unit configured to determine whether or not the machining path includes a linear path section that crosses a boundary line between a thick portion of a workpiece and a thin portion of the workpiece, a thickness of the thin portion being smaller than a thickness of the thick portion in an extending direction of the wire electrode;
- and
- a path compensator configured to compensate the machining path so as to form, in the thin portion over a predetermined distance, a protrusion projecting outward from the boundary line when the path determination unit determines that the linear path section is included.
