Abstract

The article investigates the influence of geometric parameters of CVD cutting inserts on flank and crater wear during dry turning. Turning of AISI 316L stainless steel was performed with different values of approach angles, rake angles, clearance angles, inclination angles and corner radii. After dry turning, the flank and crater wear of the cutting inserts were measured. The effects of the input parameters on the output parameters were evaluated using ANOVA. The results of the experiments showed that the flank and crater wear increases with increasing approach angle, rake angle, clearance angle, inclination angle and decreasing corner radius. Based on the test results, statistical models were developed to predict the distribution of flank and crater wear using the response surface design. The absolute and percentage errors obtained show that the models developed can be successfully used to predict flank and crater wear.
