摘　　要：现代汽车发展趋势要求各发动机厂家不仅要具有大批量生产的能力,同时也要具有小批量、多品种的生产技术。这种要求也顺理成章地延展至包括凸轮轴等在内的零部件加工。凸轮轴是内燃机配气系统中关键的零件之一,其精度要求高、但刚性差、易变形,因而加工难度大。因此,这对凸轮轴的设计、选材、加工工艺等都提出了许多要求。本文主要从某一凸轮轴机加工生产线的前期规划和工艺分析两方面就这些问题展开论述。Having being developed rapidly,the modern automobile engine industry requires an engine parts manufacturer not only has the ability to produce parts massively,but also has the technology for varieties production in small batch.These requirements also logically exist in the processing of engine camshaft.As one of the key parts of internal combustion engine system,the camshaft has high precision requirement on machining; but its poor stiffness and likely deformation makes the machining more difficult.This imposes many requirements on camshaft material,design and processing.This article mainly discusses the initial production planning and processing of a camshaft.
