【正文】 the connecting rod is demanded highly , and the rigidity of the connecting rod is not enough, easy to deform, so arranging the craft course, need to separate the each main and superficial thick finish machining process. Reduce the function of processing the surplus , cutting force and internal stress progressively , revise the deformation after processing, can reach the specification requirement for the part finally . Keywords: connecting rod, deformination, processing technology, design of clamping device機(jī)電系機(jī)電一體化專業(yè)畢業(yè)設(shè)計 i 目 錄 摘 要 ..................................................................................................................I ABSTRACT .....................................................................................................
