摘要/Abstract

摘要： 气囊抛光方法可成功应用于模具自由曲面，实现自动化抛光。提出一种面向等残余面形误差的分层修形模具气囊抛光轨迹规划新方法，该方法可用于等残余面形误差工件的整个面形修正过程或非等残余面形误差状态下气囊抛光工艺中的某一阶段。针对光栅型抛光轨迹给出一种基于一次去除深度函数数值仿真的驻留点间距优选方法，并设计了对比性实验进行验证。实验结果表明，以X方向为进给方向的光栅型轨迹中，驻留点间距值选择去除模型中最大去除量1/2处对应Y值的两倍是合理的。

Abstract: A new approach called as layering shaping gasbag polishing trajectory planning method was proposed to deal with equal residual figure error. It can be used to the whole polishing process for the workpiece with equal residual facial contour error and certain polishing stage for the workpiece with non-equal residual facial contour error. The optimal selection method of dwelling point interval under grating polishing trajectory was presented on the basis of one-time removal depth function, and the contrast experiment was designed to validate its feasibility. The experiment results show that it is reasonable to choose twice of the corresponding Y value in material removal model as the dwelling point interval if X direction is feed direction of polishing.

Key words: machinofature technique and equipment, mould, gasbag polishing, equal residual surface error, layering, trajectory planning
