针对薄壁类零件加工过程中刚性差,容易产生变形而导致形位误差超差等问题,对薄壁零件产生超差的原因进行了系统的分析,并通过对典型薄壁零件的车削工艺、夹具设计、刀具参数选取、热处理等多方面综合分析,制定出典型薄壁零件加工的一套工艺方案,有效地解决了薄壁零件加工过程中的变形及超差问题。 Aiming at the problems such as the poor rigidity and the easy deformation of the thin-walled parts during the process of machining, which leads to the out-of-tolerance of the form and position errors, the cause of over-tolerance of the thin-walled parts is systematically analyzed. Fixture design, tool parameter selection, heat treatment and other aspects of a comprehensive analysis to develop a typical thin-walled parts processing a set of technology programs to effectively solve the thin-walled parts in the process of deformation and tolerance problems.
