摘要
针对双侧圆弧凹槽的尺寸与形位公差精度要求高、细颈加工易变形等加工难题,选用了高速铣削加工控制加工精度和加工应力,并设计了可调节式夹具,提高加工细颈时的工艺系统刚度。通过分析结构特点确定刀具规格、高速铣削走刀轨迹等工艺参数,保证了细颈厚度尺寸及对称度等精度指标要求。
According to the high demand of the size,shape tolerance of the double sided concave grooves and the machining problems of deformation,high-speed milling is choosed to control machining accuracy and machining stress,and the adjustable clamp is designed to improve the inflexibility of machining process system while machining the neck.The tool specification and the process parameters such as high-speed tool path is determined through analyzing the characteristics,meetting the design requirements such as the thickness and shape tolerance of the neck.
