薄壁零件已日益广泛地应用在各工业部门,车削薄壁零件的关键是变形问题。工件产生变形的原因是:切削力、夹紧力、切削热、定位误差和弹性变形。其中影响变形最大的是夹紧力和切削力。减少切削力和切削热的方法是:合理地选择切削用量、刀具几何角度、刀具材料和切削液等;减少夹紧力引起变形主要是改善或改变夹紧力对零件的作用。对于超薄壁圆筒具体车削方法如下: 加工零件如图1所示,材料为铝
Thin-walled parts are increasingly used in various industrial sectors and the key to turning thin-walled parts is deformation. The cause of deformation of the workpiece is: cutting force, clamping force, cutting heat, positioning error and elastic deformation. Which affect the deformation is the largest clamping force and cutting force. Cutting force and cutting heat to reduce the method is: a reasonable choice of cutting, cutting tool geometry, tool material and cutting fluid; reduce the clamping force caused by deformation is mainly to improve or change the clamping force on the role of the parts. For the ultra-thin wall cylinder turning method is as follows: Machining parts shown in Figure 1, the material is aluminum
