Abstract
Description
여기서, 상기 검출공구는 절단공구 중에서 가공에 사용되지 않는 공구들 중에서 하나를 지정함이 바람직한데, 검출공구는 공작물의 가공에 따라 바뀔 수 있다. 즉, 공구 중에서 드릴이 사용되지 않는다면 상기 드릴을 검출공구로 지정해줄 수 있고 리이머(reamer)가 사용되지 않는다면 상기 리이머를 검출공구로 지정해줄 수 있다.
즉, 상기 검출공구는 일반적으로 사용되는 자동선반의 공구라면 서보모터의 부하량을 측정할 수 있는 모든 것을 검출공구로 지정하여도 무방하다.
즉, 상기 검출부재는 공작물의 가공에 사용되지 않는 파손된 공구나 일반적인 바 형태의 막대 중에서 공구대에 척킹이 가능한 어느 것을 사용하여도 무방하다. 예를 들어 파손된 드릴, 리이머, 바이트 등을 사용할 수 있다. 그러나, 다른 공구와 공구대 및 공작물과의 간섭이 없는 형태의 것으로서 보통 공구의 크기 정도인 것을 사용하는 것이 더욱 바람직하다.
Claims (2)
- 자동선반의 공작물 절단검출방법에 있어서,절단공구 이외의 공구를 검출공구로 선정하고, 상기 검출공구의 절단검출 시작점과 끝점을 입력한 뒤, 상기 검출공구가 시작점에서 끝점까지 이동될 때 아무것도 검출되지 않는 무부하 상태의 모터부하량을 1회 이상 측정하고, 측정된 모터부하량의 최대ㆍ최소값에 사용자가 임의로 지정한 소정의 값(α)을 가감하여 허용 최대ㆍ최소모터부하량의 값이 자동으로 입력된 뒤, 가공시 측정된 모터부하량의 값이 허용최소모터부하량값과 허용최대모터부하량값의 범위를 벗어나면 기계를 비상정지하는 것이 특징인 자동선반의 공작물 절단검출방법
- 제 1항에 있어서,상기 검출공구 대신 공작물의 가공을 수행하지는 않으며 검출만을 수행하기 위한 검출부재를 공구대에 장착하여 사용하는 것이 특징인 자동선반의 공작물 절단검출방법
