针对航空薄壁工件的壁薄以及结构复杂,在加工时会出现刚性低、材料去除率高以及易发生干涉等难点,分析了薄壁件加工变形与残余应力的主要影响因素。为保证在加工过程中薄壁件的刚度,研究制定了薄壁件铣削加工方案,剖析了薄壁件的结构特点,展开了加工工艺研究。根据机床特点利用UG CAM设置参数并进行后置处理,生成了相应的走刀轨迹,并运用VERICUT进行仿真加工,将验证后的加工工艺应用于实际加工中,实现了薄壁件高效率、高精密、高可靠性的数控加工。
In view of the thin wall and the complicated structure of thin-walled parts, the low stiffness, high material removal rate and interference easily occur during the processing. The main influencing factors of processing deformation and residual stress of thin-walled parts are analyzed. In order to ensure the rigidity of the thin-walled parts in the process of processing, research and development of thin-walled parts milling program, analysis of the structural characteristics of thin-walled parts, expand the processing technology. According to the characteristics of the machine tool, UG CAM is used to set the parameters and post-processing, the corresponding path is generated and the VERICUT is used to simulate the machining process. The verified machining technology is applied to the actual machining, which realizes the high efficiency, Precision, high reliability CNC machining.
