薄壁套筒零件的关键工序车削参数优化研究

Optimization Research on Key Process Turning Parameters of Thin-wall Sleeve Parts

针对薄壁零件刚性差、易变型等问题,通常在精加工完成后需进行光切,该工序虽然保证了零件的加工精度,但其严重降低了加工效率,不符合批量化、快速化的生产要求。文中依据正交试验仿真的优化理论,以某精密薄壁套筒类零件为例,构建加工质量为优化目标,对套筒件的关键切削影响因素进行了较优组合方案的探寻,以获得外圆表面车削的最优工艺参数。文中研究成果为解决车削加工尤其是薄壁件的加工变形问题提供了重要的参数指导与有效途径。

In order to solve the problems of poor rigidity and variability of thin-walled parts,it is usually necessary to light-cut them after finishing.Although this procedure guarantees the machining accuracy of parts,it seriously lags the machining efficiency,does not meet the batch and the fast production request.Based on this understanding,according to the optimization theory of orthogonal test simulation,this paper takes a precise thin-walled sleeve part as an example,constructs the processing quality as the optimization goal,and probes into the optimized combination scheme of the key cutting influencing factors of sleeve parts to obtain the optimal process parameters of turning cylindrical surface.The research results provides an important parameter guidance and an effective way to solve the machining deformation of turning,especially the thin-walled parts.
