Abstract

In this manuscript, the effect of cutting conditions (cutting speed, feed rate, and depth of cut) on the life of the cutting tool was studied in longitudinal turning operations for a sample of medium carbon iron (C35) with a length of 1200 mm and a diameter of 100 mm using a traditional turning machine and a carbide cutting tool. (P10). The experiments were designed based on three levels of cutting speed, feed, and depth of cut using the Taguchi method to reduce the number of experiments, and the (minetab16) program was used to achieve this. The level of importance of cutting conditions on the life of the cutting tool was determined by analysis of variance (ANOVA). In this study, the level of importance of cutting conditions on the life of the cutting tool was determined. Determine the optimal cutting conditions according to economic and production criteria such as the minimum total cost and the maximum production rate. The results showed that an increase in cutting speed leads to a decrease in tool life, as well as an increase in the feed rate and depth of cut. From the analysis table (ANOVA) it is clear that the cutting speed factor is the most It had an impact on the life of the cutting tool by 91.9%, followed by the feed rate by 6%, while the effect of depth of cut had the least impact on the life of the cutting tool by 1.2%. The cost and production rate, represented by the number of parts manufactured for each cutting tool, were also estimated in the practical experiments that were conducted. In light of this estimate, the optimal cutting conditions were chosen to obtain the best cutting tool life productively and economically. The results showed that the optimal cutting conditions were obtained to improve the cutting tool life in the turning process at a cutting speed of 46 m/min, feed rate of 0.1 mm/roll, and a cutting depth of 3 mm.
