Layering Shaping Mould Gasbag Polishing Trajectory Planning Method for Equal Residual Figure Error

doi:10.3969/j.issn.1000-1093.2012.06.015

Abstract

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
