Quantitative Experimental Analysis on Crater Wear of Cemented Carbide Tools

The effects of cutting parameters on the developing rate and volume of crater wear of uncoated cemented carbide tool during turning of TC4 alloy are investigated. Contour maps are used to describe the crater morphologies and study the relationship between the area of contour region and its wear depth in the case of the different cutting parameters. The evolution rate of crater wear is introduced to describe the variation rate of the area of contour region with its wear depth. The effects of cutting parameters on the developing rate of crater wear are analyzed. The volume of crater wear is obtained in the case of the different cutting parameters, and the effects of cutting speed, feed rate and material removal rate on the volume of crater wear are analyzed. The research result shows that the cutting speed is the primary factor in determining the volume of crater wear.
