The key to cold extrusion forming technology for automotive differential gears is the design and manufactur-ing of cold extrusion molds.The design of gear cold extrusion molds has been extensively studied,but manufacturing is rare-ly mentioned.This article proposes a high-speed milling processing plan for the current status of cold extrusion mold manu-facturing.In order to solve the problems of high hardness,tool wear and large tool yield in mold milling,a single factor sim-ulation test is designed based on DEEORM-3D simulation software.Through comparative analysis,the machining allowance is reasonably allocated,and the cutting parameters with small cutting force and low tool wear are selected.The method pro-posed in this article provides ideas for studying the processing technology of cold extrusion molds.
