This paper addresses the issue of unstable machining quality of large-scale high-precision internal combustion engine block; the key machining technologies of complex thin-wall internal combustion engine block are studied. This dissertation takes the L type engine block that is used as research object; the modular and fast changing fixtures have been designed for machining engine blocks; due to the fact that this kind of engine blocks has different number of cylinders, we establish a model of precision machining scheme based on virtual manufacturing technology and manufacturing method; on this basis, the scheme is applied to the actual production process to verify the feasibility of the program. The research shows that the precision machining scheme established based on virtual manufacturing technology can effectively solve the key machining technology of the engine block, and one purpose of using this method is to improve machining precision and efficiency of the assembly production. This study intends to propose final machining technology project of high-precision products, and this will formulate and gradually perfect a machining process framework for large engine block, which has engineering exploration value to promote machining technology.
