Effects of cutting parameters during turning 100C6 steel

Abstract

The objective of the paper is to evaluate the effects of cutting parameters in terms of cutting speed, depth of cut and feed rate on the influence of the surface roughness, consumed power, cutting time and tool vibrations during turning process. The material chosen in this case was 100C6 steel in dry conditions. The effects of the selected process parameters have been investigated using full factorial design of experiments (33) and the multiple linear regression (MLR). Thus, first-order empirical models were established. Analysis of variance (ANOVA) was employed to check the validity of the developed models within the limits of the factors that were being investigated and to test the significance of the above parameters. Results indicate that the feed rate is the only significant factor affecting the surface roughness. The cutting speed and feed rate are the most influential factors on cutting time. Estimated tool vibrations are functions of cutting speed, feed rate and depth of cut in decreasing order. Finally, the models obtained can be used for determination of optimal settings of cuttings parameters and this methodology should help us to obtain the best process parameters for dry turning of 100C6 steel
