Investigation of the Relationship Between Power Consumption and Noise Level During Hard Turning of CBN Tools and DIN 1.2367 Steel

Abstract

Today, dry hard turning is widely used in the processing of hardened steel due to its advantages such as low cost, high machining efficiency and green environmental protection. In this study, hard turning tests were carried out under dry cutting conditions on hardened DIN 1.2367 (55 HRC) steel material. The effect of the cutting parameters (three different cutting speeds, three feed rates and three cutting depths) on the power consumption and sound level values was investigated. Power consumption and sound intensity were evaluated using statistical approach with analysis of variance (ANOVA). In a study different from the literature, the relationship between power consumption and sound level has been tried to be revealed. According to the experimental results, as the feed rate, depth of cut and cutting speed increase; sound level and instantaneous current value are increasing. The increase in the cutting parameters increases the instantaneous current value, but the total processing time is reduced, thus reducing the total power consumption.
