正时齿轮室砂型铸造模具的优化编程加工

Timing gear chamber optimized programming and processing of the sand casting mold

依据Y485T型柴油机上用的正时齿轮室铸造模具的结构特点，通过对CAM编程走刀路径的工艺优化，生成NC程序，进行模具的高效切削加工，减少了打刀机率，从而降低模具的加工成本。本文同时讲述了该模具的主要加工步骤及其加工参数的选择。

According to the structure characteristic and casting requirements of the Timing for Y485T Diesel engine. Process optimization of CAM programming tool path to generate NC machining of the mold, reducing the probability of a knife fight, thereby reducing the processing gear chamber be used programs for efficient cost of the mold. This article about the mold processing steps and the choice of processing parameters.
