摘　　要：建立了钻削加工中进给方向毛刺的形成模型,并对钻削加工过程中出现的毛刺类型进行了归类和分析,指出影响进给方向毛刺形成与变化的主要因素。通过钻削加工试验与相应的理论分析,系统揭示出毛刺出现、形成及变化发展的基本规律,进而开发出工件叠加钻削法、钻削用量优选法、钻头参数优化法、钻头结构优改法和工件终端部材料强化法等一系列减少和抑制钻削进给方向毛刺的技术和方法,为进一步提高钻削效率和钻削加工质量开辟了新路径。This paper presents a new model f or formation of the feed-direction burr in drilling process, and the drilling burrs types are classified and analyzed. Then the main factors affecting the feed--direction burr formation in drilling are pointed out. On the basis of the experiment and theoretical analysis, the forming and changing process of burr is uncovered. Furthermore, a diverse range of measures to restrain and decrease the drilling burr have been advanced, such as overlapping warkpiece, selecting drillingparameters , adjusting drill geometry, improving drill type and so on, which opens up a new path to promote the drilling efficiency and quality.
