基于点云的超精密铣削加工三维表面形貌仿真
Three-dimensional surface topography simulation of ultraprecision milling based on point cloud
摘要
Abstract
A three-dimensional surface topography simulation algorithm for ultra-precision milling was proposed.In order to illustrate the formation of surface topography,blade point clouds which were consisted by a serial of blade points according to calculating the instantaneous locations of static discrete blade points in machining process,was introduced as the research object.Meanwhile the servo bounding boxes which were constructed by meshing simulation surface were utilized to selecting sampling points.The comparison between simulation results and measurement pictures shows that the algorithm can clearly illustrate the distribution of scallop in different directions,as well as the influence on the topography caused by initial cutter phrase.Hence,it provides a method to the research the surface topography composition in the range of ultra-precision milling machining.关键词
