摘要
以某大型精密仪器上的一个薄壁框体零件为例,通过分析零件特点,采用制定优化的工艺路线、设计合理的装夹方式、优选切削刀具以及优化切削方式与走刀路径等工艺控制策略,实现了在普通数控铣削机床上加工大型薄壁框体类零件,并有效减少了加工变形。该方法对同类薄壁框体零件的数控铣削加工具有一定的指导意义和参考价值。
Taking thin-walled frame component part in a large precision instrument as an example, through analyzing its charac- teristics, the technology strategies for controlling machining deformation, including optimizing process route, designing rational clam- ping method, choosing preferably cutting tool, optimizing cutting mode and tool path etc, were used to achieve machining large thin- walled frame component part in ordinary NC milling machine, and the machining deformation was reduced effectively. This method provides guiding and reference for NC milling of similar thin-walled frame parts.
