Abstract

본 발명은 와이어 커트 발전 가공기의 코너 형상 설정 방법에 관한 것으로, 이와 관련하여 일반적으로 사용되고 있는 방법에서는 내측의 가공의 경우 오프세트 값만큼 구부러진 원호가 부착되고 외측 코너의 경우에는 그 형상이 뽀족하게 형성되어 두 부분이 서로 간섭하여 펀치를 다이에 삽입할 수 없고, 사용자가 원호의 반경과 시점의 좌표, 종점의 좌표 및 중심의 좌표를 계산하여 입력해야 하기 때문에 번거로울 뿐만 아니라 계산의 실수로 원호가 시점이나 종점을 통과하지 않는 문제점이 발생하게 된다.The present invention relates to a method for setting a corner shape of a wire cut power processing machine. In the method generally used in this regard, a circular arc bent by an offset value is attached in the case of the inner processing, and the shape is sharply formed in the case of the outer corner. Since the two parts interfere with each other, the punch cannot be inserted into the die, and the user needs to calculate and input the radius and coordinates of the circle, the coordinates of the end point, and the coordinates of the center. Or a problem that does not pass through the end point occurs.

이에 따라 본 발명은 상기와 같은 종래의 가공 방법에 따르는 결함을 감안하여 코너 부분에서 다각형이 삽입될 코너 형상 설정 거리만 입력하여 주면 가공하고자 하는 코너의 형상이 내측 코너인지, 외측 코너인지를 판별하고 최적의 분할구간의 수와 각 분할 간격의 거리를 계산하여 각각의 분할점을 구함으로써 여러개의 직선들로 이루어진 다각형의 코너형상 설정을 자동적으로 할수 있도록 함과 동시에 다이와 펀치를 가공할 때 두가공 형상 사이에 간섭이 없게 되어 펀치를 다이 형상에 정확히 삽입할 수 있고 코너의 형상 설정을 용이하게 할 수 있도록 창안된 것이다.Accordingly, the present invention determines whether the shape of the corner to be machined is the inner corner or the outer corner by inputting only the corner shape setting distance at which the polygon is inserted in the corner in view of the defects according to the conventional machining method as described above. By calculating the optimal number of divisions and the distance of each division, each division point can be obtained to automatically set the corner shape of polygons consisting of several straight lines, and simultaneously process both dies and punches when machining dies and punches. There is no interference between them so that the punch can be inserted accurately into the die shape and the corner shape can be easily set.
