工艺参数对7050铝合金铣削表面质量的影响
Influence of Process Parameters on Surface Quality in Milling of 7050 Aluminum Alloy
摘要
Abstract
In order to explore the key effects of the surface quality in milling of 7050 aluminum alloy and the optimal processing parameters,the orthogonal experiment of 7050 aluminum alloy under the condition of flushing was carried out,and the regression model between the surface roughness and the cutting depth,feed rate and spindle speed was established.The differences of machined trace caused by the different relative states between the tool and the workpiece during the machining were analysed.The results showed that the cutting depth had the greatest influence on the surface roughness,followed by the spindle speed and the feed rate.The manifestation of the machined trace was directly related to the tool-workpiece contact state.The unidirectional arc-shaped traces could be found when the tool cut into the workpiece,mainly affecting by the cutting depth.The staggered arc-shaped traces were formed while milling in the middle of the workpiece.The shallower traces occurred when the tool cut out of the workpiece because of the feed rate.关键词
