摘要
随着微纳制造的快速发展,医疗、电子和能源等领域产品的微结构越来越复杂,精度要求也越来越高,而微结构在切削加工中易产生毛刺,极大地制约了产品的质量和性能。从切削微结构过程中毛刺的形成入手,论述了微结构毛刺形成机理的研究现状,介绍了微细毛刺尺寸的预测与表征方法。分析了切削参数、工艺规划、刀具设计和材料改性等因素对毛刺尺寸的影响,总结了毛刺的控制方法。对微细毛刺去除方法进行归纳分类,并综述了不同微结构毛刺的去除工艺及效果,探讨了目前微结构毛刺去除方面存在的瓶颈问题,指出了微结构毛刺去除方法的发展趋势。
With the rapid development of micro/nano fabrication,the microstructures of products in the medical,electronic and energy fields are becoming more and more complex and require higher precision,while the microstructures are prone to burrs in the cutting process,which greatly restricts the quality and performance of the products.Starting from the formation of burrs during the cutting of microstructures,the research status of the microstructure burr formation mechanism is discussed,and the prediction and characterization methods of microstructure burr size are introduced.The influence of factors such as cutting parameters,process planning,tool design and material modification on burr size is analyzed,and the burr control methods are summarized.The microstructure burr removal methods are classified,and the burr removal methods and effects of different microstructures are reviewed,the bottleneck problems in the removal of microstructure burrs are discussed,and the development trend of microstructure burr removal methods is pointed out.
