三维元胞自动机的铣刀片温度场影响因素的研究

Research on influence factors of temperature field on three dimensional cellular automata milling insert

铣刀片是机械加工过程中重要的切削工具,由于切削过程中的热冲击对刀片会造成严重的损毁,因此研究切削过程中刀片内部的温度变化规律十分重要。本研究在三维元胞自动机温度场模型已建立的基础上,对切削速度、切削深度、进给量对铣刀片运动的影响进行了分析,通过三维元胞自动机模型的温度传递公式,得出切削速度越快,切削深度越深,进给量越多会使铣刀片温度不断升高的结论,最终将导致刀片的破损。

Milling insert is an important cutting tool in mechanical process. Due to the serious damage for milling insert caused by the heat shock in cutting process, it is quite important to study the temperature variation regularity of the inner blade. Based on the existed three dimensional cellular automata tempera- n damage degree is studied. more cutting depth and the ＇ so as to bring more serious
