Therefore both inthe mechanical processing industry is avital link. Inmachine tool ofmechanical parts ofthe process, inorder toensure the processing precision ofthe workpiece, first ofall toguarantee the workpiece holds the correct position onthe machine, then byclamping the workpiece inthe correct position isfixed, this task isbythe machine tool fixture. For single and small batch production, the use ofuniversal fixture should beasfar aspossible, sothat the production cost ofthe workpiece can bereduced. But because the universal fixture issuitable for various workpiece clamping, soclamping tend tospend more time and the operation plex, the production efficiency islow, itisdifficult toguarantee machining accuracy, soitisnecessary todesign aspecial fixture. The design content involves the mechanical manufacturing process and machine tool fixture design, metal cutting machine tools, tolerance and measurement and other aspects ofknowledge.
