Process Design and Machining of Elliptical Shaft Assembly Parts

椭圆轴装配零件是数控车床常见的车削对象,此零件主要技术难度在于内外轴及螺纹配合和局部椭圆面车削加工,为解决内外螺纹配合要求、椭圆面车削,对零件进行合理加工工艺设计、确定装夹方案、选择刀具和切削用量,从而加工出合格零件,保证零件加工尺寸和质量,达到图样设计要求。

The elliptical shaft assembly parts is a common turning object of CNC lathe.The main technical difficulty of this part is turning on the internal and external shaft,the thread matching and the local ellipse surface.In order to meet the requirements of the internal and external thread matching,the ellipse turning is made.The reasonable machining process design,the clamping scheme,the selection of tools and cutting parameters,so as to process qualified parts,guarantee the size and quality of parts processing,and meet the requirements of drawing design.
