According to process requirements and routes of a diesel engine’s crankshaft, special fixture design programs were analyzed, based on a machining process of one of the crankshaft’s support surfaces, and the special fixture’s positioning accuracy was analyzed. The special fixture design program consists of analyses of a location mode of the crankshaft’s support surface and a kind of structure of the locating element, options of the clamping mechanism and options of the tool-setting elements and guide elements. The analyses of the special fixture’s positioning accuracy show that the special fixture location mode is feasible.
