In order to improve the NC machining efficiency of casting sand mold, shortterm merger and control mode adjustment were adopted to optimize machining path, and the micron grade point path length was optimized by combination of backward search method and forward search method.NC machining path optimization model was established.It was applied to the largescale complex casting sand mold processing, the processing time was shortened and the processing efficiency was improved.
