摘要
针对薄壁零件刚性差、一般结构复杂、精度高，所以在数控加工中变形难以控制，无法保证加工质量的问题，提出了进给量局部优化，优化过程分为四步：修改切削参数、确定关键区域、确定边界点、修改刀位文件。局部优化可减少加工时间、提高效率，是一种方便、有效的优化方法。
Because of the complicated structure, bad rigidity and high accuracy of thin-wall parts, it is difficult to control the deformation and guarantee the machining quality in NC process. In this paper, the authors put forward the local optimization approach of feed rate. The process of optimization includes four steps, that is, modification of cutting parameters, identification of key areas, determination of boundary points and modification of CL files. It is proved that the approach of local optimization of feed rate can decrease machining time and increase efficiency. So, it is a kind of convenient and effective method.
