摘　　要：在钻削高硬度材料时,钻头结构的合理选择关系到工件钻削的加工效率和成本。对钻削过程中的钻头磨损及寿命进行分析,并对不同结构的电沉积金刚石钻头使用有限元软件进行仿真分析及优化,以提高电沉积金刚石钻头在钻削SiC陶瓷材料时的钻削性能。从多个角度分析排屑对于提高电沉积金刚石钻头钻削高硬度陶瓷材料的可钻削性和钻头寿命的重要性,通过两种试验得出钻削扭矩、钻头磨损、工件表面质量与钻头结构的关系趋势,并据此设计出最佳电沉积金刚石钻头结构。When drilling high hardness materials,the reasonable selection of bit structure is related to the efficiency and cost of workpiece drilling.The wear and life of drill bits during drilling are analyzed,and the finite element simulation analysis and optimization of diamond electro-deposition drill bits with different structures are carried out to improve the machinability of diamond electro-deposition drill bits in drilling SiC ceramic materials.In this study,the importance of chip removal for improving the machinability and tool life of diamond electro-deposition drill in machining high-hardness ceramic materials is analyzed from multiple perspectives.The relationship between drilling torque,tool wear,workpiece surface quality and tool structure is obtained through two experiments,and the optimal electro-deposition diamond drill structure is designed accordingly.
