摘　　要：研究机床、刀具和工件参数对切削过程的影响以及车削时实际切削厚度与支撑部件变形的关系,建立其数学模型,提出了按轨迹法加工切削厚度的函数。并讨论了机床弹性系统的柔度对切削厚度的影响。在设计机床和确定切削用量时,利用该数学模型确定对支撑部件刚性的要求。The effect of parameters of machine tools, cutting tools and parts on cutting process were researched, and the relation between the real cutting thickness in turning and distortion of the support parts was studied, then the mathematical model was built, and the function of cutting thickness in machining on locus could be obtained, meanwhile, the influence on cutting thickness of compliance of machine tool elastic system was discussed. Applying the mathematical model the rigidity of the support parts would be decided with designing machine tools and determining cutting parameters.
