<p>PROBLEM TO BE SOLVED: To provide a wire electric discharge machine performing path correction in a concave arc corner part, a machining path generation device for the wire electric discharge machine, and a machining method using the wire electric discharge machine capable of improving machining accuracy by correcting a program locus and machining path in the concave arc corner part.SOLUTION: A machining program is passed from machining program storage means 21 to machining program analysis means 22. The machining program analysis means 22 analyzes the machining program to extract the data related to a program locus and passes the extracted data to program locus generation means 23. The program locus generation means 23 receives the data related to the program locus from the machining program analysis means 22 and generates the program locus. Program locus correction means 24 inserts such a shape that advances from the end point to the start point of the concave arc passing through the inside of the concave arc and advances back from the start point to the end point on the concave arc, into a concave arc corner part of the program locus.</p> |
