摘　　要：干式磨削具有加工效率高、加工成本低、环境污染小等优势,广泛应用于模具加工制造行业。作为零件制造工艺链的最后环节,磨削加工后的工件表面完整性决定了产品质量和使用寿命。以淬硬模具钢ANSI D2为加工对象,通过实验研究干式磨削条件下磨削淬硬模具钢的加工表面完整性,分析并确定了进给速度、磨削深度等磨削参数对磨削表面层的组织结构、表面层显微硬度、加工表面粗糙度、残余应力分布等表面特性的影响规律,为制订合理的磨削参数、实现淬硬模具钢干式磨削工艺的优化提供指导。Dry grinding was widely used in the manufacturing of mold because of its advantages in-cluding high machining efficiency,low cost and little pollution.As one of the last steps in the manufac-turing process,the ground surface integrity determined the product quality and life.Herein surface in-tegrity of hardened mould steel ANSI D2 under dry grinding was experimentally studied.the influ-ences of feeding speed and cutting depth on surface integrity including the surface structures,micro-hardness,surface roughness and residual stress were studied,which provides guidance for the determi-nation of grinding parameters and the optimization of dry grinding process of hardened mould steel.
