摘　　要：提出了气液混合功能电极电火花诱导烧蚀铣削加工方法,并进行了针对Cr12的铣削试验,与常规电火花铣削进行对比和分析,发现气液混合烧蚀铣削的加工效率可达96.3 mm/3min,而常规电火花铣削的加工效率仅为6.4 mm/3min。从工件表面微观形貌、能谱及成分分析等方面进行研究,解释了加工效率高的原因。最后研究了不同加工参数下,气液混合功能电极电火花诱导烧蚀铣削加工效率的工艺规律。A spark-induced ablation technology is put forward based on gas-liquid mixture function electrode, and spark-induced ablation milling experiments is conducted of Crl2. Comparing and ana-lyzing with traditional spark milling shows that efficiency of spark-induced ablation milling can reach up to 96.3 mm^3/min, while the efficiency of traditional spark milling is 6.4 mm^3/min. The processing efficiency, surface quality are analyzed and the cause that make the efficiency high is explained. Final-ly, the process rules on spark.induced ablation milling is studied by gas-liquid mixture function elec-trode under different machining parameters.
