On the Influence of the Speed-Feed Interaction on the Wear Rate and Life of Multiple Coated Carbide Inserts Considering Rough Turning Process

Abstract:

The impact of the cutting parameters; speed, feed, and depth of cut on the wear and the life of the cutting edge has long been a matter of debate among researchers. The cutting speed has long been agreed to have a prime influence in such a way that increasing speed leads to higher wear rate. Depth of cut has been concluded by majority of studies to have insignificant or negligible impact on edge wear and deformation. Despite its long established influence on the roughness of the machined surface, the effect of cutting feed on edge wear and deformation still requires more explanation. Cutting feed is a crucial parameter governing the product surface finish and dimensional accuracy and, therefore, its attitude during machining should be fully understood. This study presents experimental and modeling approach to detect the feed-wear functional interrelation considering various domains of the cutting speed. Results showed that the impact of the cutting feed is firmly associated with the level of cutting speed employed. Speed-feed interaction proved to be responsible for the performance of the cutting edge during machining.
