Abstract

본 발명은 와이어 컷 방전 가공기의 코너 가공방법에 관한 것으로, 연속하는 두 개의 직선 블럭 사이에 모따기를 하고자 할 때 모따기 양만을 입력하면 모따기 양에 따른 모따기 블럭의 시작점 및 끝점을 자동적으로 계산함에 따라 정확한 모따기를 수행할 수 있을 뿐만 아니라, 모따기 양만 입력하면 되므로 가공 프로그램을 손쉽게 수정할 수 있는 것이다.The present invention relates to a corner processing method of a wire cut electric discharge machine, and when a chamfer is input between two consecutive straight blocks, inputting only the chamfer amount automatically calculates the start and end points of the chamfer block according to the chamfer amount. Not only can you perform chamfering, you only have to enter the amount of chamfering so that you can easily modify the part program.
