摘要：作为一种重要的微小型精密零件加工工艺，微细铣削在铣削过程中产生的毛刺严重影响其加工质量及加工效率。为有效减小微细铣削过程中的毛刺尺寸，运用有限元分析软件DEFORM对微细铣削不锈钢材料的关键因素(轴向切深、每齿进给量、主轴转速及径向切深)进行有限元分析，得出了毛刺尺寸最小的优化铣削参数，并通过微细铣削试验验证了有限元分析结果的正确性及合理性，说明有限元仿真可以有效指导铣削试验，从而降低试验成本，提高试验效率。

Abstract:The micro milling is an important process for machining miniaturized parts，but the burrs generated in process can seriously affect the machining quality and efficiency.In order to reduce the burr size，the key milling parameters such as axial depth of cut，feed engagement，spindle speed and radial depth of cut are firstly studied by the finite element simulation software DEFORM to get the optimal parameters for the minimal burr size in micro milling stainless steel.Then，the micro milling experiment is carried out，the correctness and rationality of the simulation results are authenticated.The simulation method can effectively guide the actual experimental machining，so as to decrease the experiment cost and enhance the efficiency.
