A tool-path planning method used in computer controlled optical surfacing based on improved prim algorithm

In view of the disadvantages existing planning methods used in CCOS techniques, such as low efficiency and workpieces containing obvious mid-frequency error after polishing, a new tool-path method based on improved Prim algorithm is presented. The core idea consists following steps: surface data reading, mesh generation, distribution resident points determining, polishing path generating. Then, comparison raster are carried out by simulations from aspects length texture. results indicate that can shorten well increase efficiency; moreover, both texture errors be using Finally, processing experiments presented out. experimental show precision proposed method. Moreover, it reduce workpiece effectively. Thus, which good agreement with simulation prove feasibility
