Abstract

Selecting appropriate cutting parameters is essential to prolonging tool life and maintaining machining quality. This study analyzes the effect of depth-of-cut variation on the wear of carbide cutting tools during dry turning of S45C steel, focusing on flank wear and crater wear. An experimental method was employed using three depth-of-cut levels (1 mm, 2 mm, and 3 mm), a constant feed rate of 0.2 mm/rev, and wear measurement using a digital microscope. The results show that increasing the depth of cut from 1 mm to 3 mm increased flank wear from 0.0186011 mm to 0.0325576 mm, crater wear from 0.0005118 mm to 0.001432 mm, and cutting temperature from 28.9°C to 30.1°C. All measured wear values remained below the 0.3 mm critical limit specified by ISO 3685, yet the upward trend confirms that depth of cut meaningfully accelerates tool wear. A depth of cut of 1 mm is recommended to prolong tool life and maintain machining quality in medium-carbon steel turning
