薄壁盘套类零件的装夹规划算法研究

IThe part manufacturing models, setups and operations are defined to solve the setup planning of the thin-walled turning part. A mathematical model of setup planning is developed based on discussions about machine types, tool approach directions and operation precedence constrains. The setup planning is divided into three sub-problems to decrease the problem solution space according to grading for the thin-walled turning part. An algorithm based on rules, graph theory and clustering is introduced to determine setup planning precedence and operation groups in process of solving the sub-problems. A complete setup planning is put forward for the thin-walled turning part. Finally, an example of the aviation part is illustrated to prove feasibility of the proposed model.
