The processing demand put forward according tothe part picture, confirm the manufacture form ofthe blank and sureness ofthe size. The second step, carry onthe choice the base ,confirm thick datum and precise datum inthe processing course. According tothe datum chosen ,make the craft route ,usually make the craft route ofmore than two kinds, with analysing through parison ofthe craft scheme, and then choosing beable tomake such specification requirements asthe precision ofgeometry form , size ofthe part and precision ofposition ,etc. get akind ofprocess ofthe rational
