随着汽车行业对新一代发动机的开发和应用,对铸件质量的要求愈来愈高。气缸盖铸件对提高发动机的性能有着举足轻重的作用,其进、排气道的几何形状直接影响发动机的性能参数。本文描述的是:如何应用逆向设计—制造工艺,运用配置计算机的座标测量仪对进、排气道轮廓进行扫描,生成数据文件,运用计算机辅助设计CAD和计算机辅助制造CAM对这些数据进行处理、改进,得到理想的进排气道实体轮廓。 With the automotive industry on the development and application of a new generation of engines, casting quality requirements are getting higher and higher. Cylinder head casting to improve the performance of the engine plays a decisive role, its intake and exhaust geometry directly affects the performance parameters of the engine. This paper describes how to apply the reverse design-manufacturing process to scan the inlet and outlet profiles using a coordinate measuring machine equipped with a computer to generate data files that are processed using computer-aided design CAD and computer-aided manufacturing CAM , Improve, get the ideal inlet and outlet physical outline.
