钛合金TC4高速铣削表面微观几何形貌仿真

Prediction of Surface Roughness of Ti Alloy TC4 on High Speed Milling

通过几何微观形貌仿真,可以预测表面粗糙度,为优化铣削参数提供依据。建立了球头铣刀的数学模型,考虑了铣刀的倾斜方向、倾斜角度、进给方式、主轴的回转偏心、轴向窜动等因素对加工表面的影响,并开发了微观形貌的仿真算法。并通过对比试验数据,说明仿真的可行性。

The surface roughness of the machined work piece can be predicted by the simulation of the micro-geometrical texture,so as to optimize and select the machining data.This paper also makes a study of the influence of cutting edge shape,tool titling direction,titling angle,feeding mode,run-out of spindle and periodic axial slip,etc.on machined surface roughness in the case of ballend mill machining.The results indicates that the simulation method developed in this paper is efficient.
