Evaluation And Modeling Of The Effect Of Tool Edge Radius On Machined Surface Roughness In Turning Uns A92024-T351 Aluminum Alloy, Ning Fang, P. Srinivasa Pai

Engineering Education Faculty Publications

Tool edge radius plays a significant role in affecting the surface integrity of machined products. The vast majority of existing research, however, takes no account of the effect of tool edge radius in the evaluation and modeling of machined surface roughness, an essential indicator of surface integrity. The present study fills this important research gap and has performed a total of 45 turning experiments on Unified Numbering System (UNS) A92024-T351 aluminum alloy with carefully selected cutting tools with three levels of tool edge radii. This article describes the experimental setup and measurements of tool edge radius and machined surface roughness. …
