以某大型薄壁深腔大角度关键结构件为研究对象,在数控立车设备上,首先通过设计车削加工夹具,选用专用机夹刀具和选择合理的切削参数,其次通过工艺优化控制零件加工过程中的切削变形和热变形,并考虑了深腔出屑和让刀等问题。结果表明,本文方法可以实现该复杂零件的加工并保证其加工精度。 With a large thin-walled deep cavity large angle key structural parts as the research object, the CNC vertical lathe equipment, first through the design of the lathe machining fixture, the choice of special machine tool and select the appropriate cutting parameters, and secondly through the process optimization control parts machining process Cutting deformation and thermal deformation, and consider the deep cavity of debris and let the knife and other issues. The results show that this method can realize the processing of the complex parts and ensure the machining accuracy.
