【Abstract】 The application of genetic algorithm for the surface roughness pred iction model in ultra-precision turning is proposed by a practical example Mathe matics model is introduced and optimal results are given. The prediction model u sing genetic algorithm are compared with least square method results. Comparison shows that genetic algorithm is more suitable than traditional optimal methods.更多还原
