정면밀링공정에서 공구마모에 따른 절삭력 신호의 형상 변화에 관한 연구

On-line detection system of abnormal states in a machining process needs to be developed to implement the IMS(Intelligent Manufacturing System). Generally it is difficult to determine the exact point of time for tool change because a tool wear grows progressively on the contrary to other abnormal states. In this article, the shape parameter of cutting force within 1 revolution was proposed as a feature to detect a tool wear. The feasibility of the shape parameter was discussed and verified through the tool wear experiments.
