摘要

数控抛光能够达到一致性较高的表面粗糙度要求。试验研究了羊毛毡轮数控抛光层数对磨削后GH4169 表面残余应力的影响，进给方向表面残余正应力随深度增加先升高后下降，而垂直进给方向表面残余正应力先基本不变后下降，优化抛光层数为3 层。针对磨削后抛光工艺，提出了“加强筋”模型，将羊毛毡轮抛光过程分为两个阶段，解释了抛光对表面残余应力的影响机理，并改变抛光参数进行了初步的试验验证。

Abstract

CNC Polishing can have a low roughness with a high consistency. The influence of CNC polishing of wool felt wheel on residual stress is investigated. The normal residual stress in the feed direction shows a trend from rise to decline

while in the vertical feel direction it stays unchanged basically and then decreases. The optimized times of polishing is 3. The “Reinforcing Bar” model is put forward in order to explain the impact on the residual stress from polishing. Another polishing experiment is conducted for verifying roughly the impact relation.
