Inprocess design should first ofall parts for analysis, tounderstand part ofthe process todesign blank structure, and choose the good parts machining datum, design the process routes ofthe parts; then the parts ofeach step inthe process tothe size calculation, the key istodetermine the craft equipment and the cutting dosage ofeach working procedure design; then the special fixture, the fixture for the ponents ofthe design, such asthe connecting part positioning devices, clamping element, aguide element, fixture and machine tools and ponents; positioning error calculated bythe analysis offixture, jig structure the rationality and the deficiency, pay attention toimproving and will design in. Keywords : process, cutting dosage, clamping, positioning 目录目录......................................................................................................................................... 1 1序言..................................................................................................................................... 2 2零件的分析............................................................................................................................. 3 零件的形状.................................................................................................................. 3 零件的工艺分析.......................................................................................................... 3 3工艺规程设计.....
