一、概述在机械加工过程中,由于各种形式的毛刺存在,给加工、装配、检验、产品的性能、使用寿命以及安全和外观上都带来一定问题。因此毛刺的去除问题越来越引起人们的重视。当前,数控技术、计算机管理在生产中广泛应用,使生产自动线和无人化车间不断出现,迫使去毛刺工艺也要有一个相应的发展和深入研究。国外统计,手工去毛刺的作业费用约占零件工时费用的5～30％,对于高精度小零件来说,去毛刺的费用与加工费用相差无几。据报导,美国工业去毛刺的作业费每年达60亿美元之多。因此,毛刺去除技术不提
First, an overview In the machining process, due to the existence of various forms of burrs to the processing, assembly, testing, product performance, service life and safety and appearance are brought some problems. Therefore, the removal of burrs more and more aroused people’s attention. At present, numerical control technology and computer management are widely used in production, making the automatic production lines and unmanned workshops appear constantly, forcing the deburring process to have a corresponding development and in-depth research. Foreign statistics, manual deburring operating costs account for about 5 to 30% of the part-time costs, for high-precision small parts, deburring costs and processing costs are almost the same. It is reported that the operating costs of U.S. industrial deburring amount to as much as $ 6 billion annually. Therefore, burr removal technology does not mention
