PROBLEM TO BE SOLVED: To improve machining accuracy in multi-path machining of a reentrant corner portion by a wire-cut electric discharge machine.;SOLUTION: The controller and the machining path generation device for the wire-cut electric discharge machine include: a machining program storage means 1 for storing a machining program; an offset amount storage means 6 for storing a wire offset amount for each machining operation; a machining program analysis means 2 for analyzing the machining program; a machining shape definition means 3 for creating a machining shape of a workpiece based on the result of an analysis by the machining program analysis means 2; a machining shape correction circular-arc radius storage means 7 for storing a predetermined circular-arc radius used to correct the machining shape; and a circular arc insertion means 4 which eliminates opposite end portions of the reentrant corner portion formed of two intersecting nonparallel motion blocks and inserts a circular-arc motion block with the predetermined circular-arc radius into the eliminated portion, if the machining shape defined by the machining shape definition means 3 includes the reentrant corner portion.;COPYRIGHT: (C)2010,JPO&INPIT
