정면 밀링 가공에서의 비절삭 저항 모델링 및 절삭력 예측

In order to establish automation or optimization of the machining process, predictions of the forces in machining are often needed. A new model for forces in milling with the experimental model based on the specific cutting pressure and the Oxley’s predictive machining theory has been developed and is presented in this paper. The specific cutting pressure is calculated according to the definition of the 3 dimensional cutting forces suggested by Oxley and some preliminary milling experiments. Using the model, the average cutting forces and force variation against cutter rotation in milling can be predicted. Milling experimental tests are conducted to verify the model and the predictive results agree well with the experimental results. KCI Citation Count: 2
