摘　　要：综合国内外研究现状,介绍了枪钻的基本结构和加工系统,总结了枪钻加工过程中刀具磨损的主要形式:扩散磨损和粘结磨损,分析两种磨损形式的机理。阐述了枪钻加工过程中刀具监测技术,目前主要通过采集力、扭矩和声发射信号对刀具状态进行监测,声发射信号等可以对刀具磨损状态进行表征,提出了抑制枪钻磨损方法以及监测技术的发展趋势。Basic structures and machining system are introduced in this paper. Main tool wear forms,adhesion wear and diffusion wear,are discussed. Wear mechanisms are detailed analyzed. TCM（ tool condition monitoring） in gun-drilling is stated. Force signals,torque signals and AE（ acoustic emission） signals are used for monitoring tool condition in many researches. AE signals can be classified with different tool wear forms. At last,methods to reduce tool wear and development trends in gun-drilling are put forward.
