切削参数对Ti-6Al-4V锻件与粉末冶金工件表面粗糙度的影响对比
Comparative on Influence of Cutting Parameters on Surface Roughness of Ti-6Al-4V Forging and Powder Metallurgy Workpieces
摘要
Abstract
In this paper,surface morphologies of Ti-6Al-4V forging and powder metallurgy workpieces were characterized,surface roughness mathematical models of the two machined workpieces were developed using orthogonal regression test,and the significances of the mathematical models were verified,the surface roughness mathematical models could predict the surface roughness changing trends.The experimental results showed that feed scratch,chip fragment and surface tearing defects appeared in the machined Ti-6Al-4V forging surface,while micro-void defect was formed in the machined powder metallurgy material surface apart from the feed scratch,chip fragment and surface tearing defects.The influence of feed rate on the surface roughness of both workpieces is greatest,and the existence of internal micro-void of Ti-6Al-4V powder metallurgy material led influence of cutting speed greater.关键词
