Study on the Analytical Prediction of Premier Chipping in Involute Gear Cutting Process
인볼류우트 커터인선의 초기결손 예측에 관한 연구
- Published : 1992.07.01
Abstract
In the machining processes, the tool chipping are known to be the most dangerous when the variation of end of tool edges is largest. Therefore, chipping has been caused by the stress distribution in the moment of cutting. In this study, in order to predict the shapes of tool chipping with the tool shapes and the cutting conditions, the premier chipping shapes of involute cutter iss predicted by the stress distribution value of cutting edges and it is verified by the experiments. The growth behavior of the tool chipping is considered through the experiment of gear cutting and in case of evaluation of specific cutting energy in the proper machining conditions through the simulation result, it can be known that the prediction of cutting force is possible accurately.
본 연구에서는 공구의 형상과 절삭조건에 따른 공구의 결손형태를 예측하기 위하여 현재 가장 널리 쓰이고 있는 인볼류우트커터의 결손형태를 절삭날의 응력분포 값으로 예측하고 실험에 의하여 검증함과 동시에 기어 절삭실험을 통한 공구 결손의 성장거동을 고찰하였으며, 또한 마멸과 결손이 발생함에 따른 절삭력의 변화와 평형을 관찰하여 상호관련성을 비교함으로써 인볼류우트 기어커터의 초기 결손을 해석적으로 예측하였다.
