Effect of the cutting angle and the depth of cut toward wear of carbide tool on the lathe

Abstract

The following paper discusses how the effect of the angle and the depth of cut toward wear and tear of chisel on the lathe, then sought relationship influence of both. In this study, the wear and tear of the chisel to be studied is the edge wear (VB). The varied machining parameters are cutting angle and depth of cut. Variation of cutting angle is equal to 60°, 75° and 90°. While the depth of cut is varied by 0,5 mm, 1,0 mm and 1,5 mm. The lathe used is a conventional lathe with 400 rpm spindle spin. After testing the wear of chisel, it can be concluded that the greater the angle of cutting the higher the level of wear chisel. So also on the variation of cut depth, the greater the depth of cut then the higher the wear rate of the chisel also. From the factorial test also shows that the cutting angle and depth of cut have a close relationship in the process of forming the tool wear.
