摘 要
凸轮轴作为汽车发动机配气机构中核心部件，其性能直接影响着发动机整体性能。因而凸轮轴加工工艺有特殊规定，合理加工工艺对于减少加工成本、减少生产环节以及合理布置凸轮轴生产线具备很大现实意义。本文针对凸轮轴加工特点，结合工厂实际，从前期规划开始，对凸轮轴加工工艺进行了进一步分析、研究。对凸轮廓形进行计算和推倒，对凸轮轮廓加工进行了探讨并提出合用于发动机凸轮轴加工办法。凸轮轴对其工作规定、某些精度较高，如轴上油孔加工、法兰盘孔加工等。凸轮轴工艺过程，咱们尽量做到清晰明了，在保证表达清晰基本上，尽量做到简洁。凸轮轴是轴类零件中比较复杂一种曲轴，而在磨削加工方面，凸轮轴也是比较难以加工轴，这种轴类零件加工办法普通都是大同小异。凸轮轴加工普通是先通过车床车削加工，制成半成品；然后通过相应热解决；再就是对凸轮轴各某些磨削加工；最后就是通过有关工序解决和检查合格后就可以入库了。

ABSTRACT
Camshaft Engine Valve as a key component in its performance directly affects the overall performance of the engine. Therefore，the processing technology camshaft has specific requirements for a reasonable process to reduce processing costs，reduce production processes and the rational arrangement of the camshaft production line of great practical significance. In this paper，the processing characteristics of the camshaft，with the actual plant，starting from the pre-planning，on the camshaft of the process conducted in-depth analysis and research. Convex contour shape of calculated and pulled down the processing of the cam profile are discussed and made applicable to the processing method of the engine camshaft. Camshaft its work requirements，some high precision，such as the axis of the hole of the process，the flange hole processing. Camshaft process，we have clarity as far as possible，in ensuring the basis of clear，concise and as far as possible. Cam shaft of the more complex is a crankshaft，and in the grinding，the cam shaft is relatively hard to process，this shaft parts are generally similar to those of processing methods. Camshaft after the processing is generally the first turning lathe，made of semi-finished products；and then
