Abstract：In order to improve the surface machining quality of small precision parts in the cutting process, the surface roughness of small precision parts was taken as the objective function,and a series of cutting experiments for small precision parts were designed and implemented.The influence of such processing parameters as cutting depth,cutting speed and supply quantity on the objective function was analyzed with the single factor test method.With the multiple linear regression analysis method,the relationship model between the cutting parameter and objective function was established so as to obtain the best combination of processing parameters,and the experimental verification was carried out.The results show that the cutting speed and cutting depth have negative effect on the surface roughness,while the supply quantity has positive effect.After the combined machining with the optimization parameters,the uniformity of surface roughness of workpieces is better,and the surface quality of products gets greatly improved.
