报导了作者通过实物反求(RE)获得流道表面数据,在CAD环境下对获得的数据进行处理,并确定其成型模具分型曲面,最后用CAM系统完成模具加工。作者运用这种将逆向工程和数控加工技术相结合的模具设计制造方法,能够提高模具和产品的精度、降低模具和产品的成本、缩短模具制造周期、提高产品质量。

One processing that the writer obtained the gas guide data of engine by reverse engineering technology, then processed those obtained data in CAD environment, established the mould surface to split the mould, at last accomplished machining by CAM system was presented and discussed. It be proved that this processing integrated reverse engineering and NC technology can advance the machine precision, reduce cost of the product, shorten manufacture cycle of mould, improve the quality of the product.
