It is a situation in high workload and poor realizability to find the optimization parameters of the grinding by using experimental method. Taking X-Y linkage plane grinding as the platform, influence of grinding quality with 4 factors including initial diameter of the abrasive, initial phase angle, lapping plate ＆ workpiece speed ratio and X-Y linkage workbench through simulation is studied. The results show that initial radius vector of the abrasive basically has not effect on grinding trace. When speed ratio between lapping plate with workpiece is decimal the grinding trace seems much better. The significant influence of grinding quality can made by straight and helical X-Y linkage motion on workbench展开更多

The feature setup generation and machining sequence can be determined automatically in this system. The set of knowledge-based rules for process planning and manufacturability evaluation is provided and can be shared by all stages of full product life-cycle. An approach for MTAD (Multiple Tool Axis Direction) feature setup generation is presented and the appropriate Tool Axis Direction(TAD) is chosen to minimize the total setup numbers of a part.
