摘要: 螺旋槽的加工是回转体刀具加工的重要组成部分,其形状参数(尤其是前角、槽深和槽宽)对刀具的切削过程有很大的影响.基于6-UPS并联机床,在分析并联机床加工工艺特性的基础上,按照螺旋槽加工中砂轮与刀具的相对运动关系,建立了螺旋槽加工运动的理论模型,对可能影响螺旋槽成形的因素进行了全面分析.进而建立了一个仿真模型,可以对所有的磨削参数进行快速的定量设计和优化,主要包括砂轮偏转角度、砂轮厚度、砂轮轴向平移位置和螺旋槽深度,并通过加工实验进行了验证.

Abstract: The flute machining is important to produce a milling cutter. The geometric parameters (especial its rake angle,flute depth and flute width) have essential influence on the performance of the tool. Using a 6-UPS parallel machine,based on analyzing its special machining and structure features,general analysis was given for all factors which will influence of flute forming,and according to the motion relation between grinding wheel and the milling cutter,a simulation model system was established,that can optimize and quantitative design all of the parameters quickly. These parameters include the grinding wheel deflexion,the grinding wheel thickness,the grinding wheel offset position along the axes direction,and the flute depth. These parameters have been verified by experiments.
