Development and application of surface generation technology for ultra-precision machining

针对超精密加工表面生成机理的抽象性和复杂性问题,提出表面生成建模方法,并应用于超精密加工实验教学中,弥补超精密加工实验数量不足。该方法既直观地展示超精密加工表面形貌特征,又充分地呈现超精密加工参数对表面生成的影响。从车削表面生成的构建与仿真到较复杂的飞刀铣削表面生成的建模与仿真,让学生认知超精密加工表面生成机理,加深理解超精密加工参数的影响机制,培养学生科学问题的探索能力和科研兴趣。

In view of the abstraction and complexity of surface generation mechanism in ultra-precision machining,a surface generation modeling method is proposed,which is applied to the experimental teaching of ultra-precision machining to make up for the shortage of ultra-precision machining experiments.This method can not only visually display the surface morphology characteristics of ultra-precision machining,but also fully show the influence of ultra-precision machining parameters on surface generation.From the construction and simulation of turning surface generation to the modeling and simulation of complex flying-cutter milling surface generation,students can understand the mechanism of ultra-precision machining surface generation,which can deepen their understanding of the mechanism of ultra-precision machining parameters and train their ability to explore scientific problems and interest in scientific research.
