【摘要】 Stellite6合金常被堆焊到其它金属基体表面形成耐磨层，这种堆焊的耐磨层表面在使用时需要较小的表面粗糙度，常以磨削完成其精加工。采用高速铣削已经可以在很多金属表面的精加工中实现“以铣代磨”。为在Stellite6合金堆焊层表面的加工中实现“以铣代磨”,通过高速铣削试验，运用正交与单因素试验法研究了主要切削参数对Stellite6合金表面粗糙度的影响规律，并建立表面粗糙度的经验计算公式。结果表明：高速铣削Stellite6合金的表面粗糙度为0.3～0.5μm,能够实现“以铣代磨”,且对表面粗糙度影响最大的因素为每齿进给量，影响最小的因素为切削宽度。更多还原

【Abstract】 Stellite6 alloy is often overlaied onto the surface of other metal substrates by the welding to form wear-resistant layers, and the small surface roughness is required on the wear-resistant layers for in usage, and the precision machining are often finished by grinding. The "milling instead of grinding" can be achieved in precision machining of many metal surfaces by high-speed milling. To realize "milling instead of grinding" in the processing of Stellite6 alloy overlaid surface, the influence of the main cutting parameters on the surface roughness of Stellite6 alloy is studied in high-speed milling by orthogonal and single-factor test methods, and the empirical calculation formula of surface roughness is established. The results show that the surface roughness of machined Stellite 6 alloy by high-speed milling is 0.3～0.5 μm, realizing the milling instead of grinding effect. It’s also found that the feed per tooth has the greatest effect on surface roughness while the cutting width has the least effect on surface roughness.更多还原
