Abstract

본 발명은 수치 제어 장치의 사이클 가공 방법에 관한 것으로, 종래에는 폐루프 선삭 사이클일 경우 피삭재가 존재하지 않는 부분에서는 급송 이송으로 다음 위치로 이동하여야 하는데 불필요한 절삭 이송을 하므로써 가공시간을 낭비하게 되고 또한, 복합 고정 사이클일 경우 폐루프 선삭 사이클보다는 효율적인 가공을 하나 피삭재의 형상이 원통형일 경우에만 가공 기능이 최대한 발휘되므로 피삭재를 효과적으로 가공할 수 없는 문제점이 있었다. 이러한 문제점을 개선하기 위하여 본 발명은 피삭재 형상과 최종 가공물의 형상을 동시에 정의하여 두 윤곽 사이의 부분만을 절삭 이송하므로써 불필요한 절삭 이송을 제거하여 가공 시간을 단축시키는 방법을 제공하는 것으로, 본 발명은 1차로 가공된 임의의 형상을 가진 피삭재와 최종 가공물의 형상 사이의 부분만을 절삭 이송하여 최소의 이송 경로를 발생시키므로써 가공 효율을 향상으로 생산성 증대를 이를 수 있다.The present invention relates to a cycle machining method of a numerical control device, and in the conventional closed loop turning cycle, the part where no workpiece is present has to be moved to the next position by rapid feed, which wastes machining time by unnecessary cutting feed. In the case of a complex fixed cycle, the machining process is more efficient than a closed loop turning cycle, but only when the shape of the workpiece is cylindrical, the machining function is exhibited to the maximum. In order to solve this problem, the present invention is to provide a method of reducing the machining time by eliminating unnecessary cutting feed by cutting only the portion between the two contours by defining the shape of the workpiece and the shape of the final work at the same time, the present invention 1 By cutting and conveying only a portion between the workpiece having an arbitrary shape processed into a car and the shape of the final workpiece to generate a minimum feed path, productivity can be increased by improving processing efficiency.
