Investigation of turning in different cutting parameters of Al 6061 with finite elements method

In this study, the effects of cutting parameters on cutting force, temperature and stress were investigated in the turning of 6061 aluminum alloy by using DEFORM-3D package program based on finite element method. Constant depth of cut (1 mm), three different cutting speeds (40, 60 and 80 m/min), and three different feed rates (0.05, 0.1 and 0.15 mm/rev) were used in research simulations. From the made analyses, the lowest cutting force was obtained as 150 N at 80 m/min cutting speed and 0.05 mm/rev feed rate, the highest cutting force was obtained as 368 N at 40 m/min cutting speed and 0.15 mm/rev feed rate. While the lowest temperature was obtained as 230 °C at 40 m/min cutting speed and 0.05 mm/rev feed rate, the highest temperature was obtained as 354 °C at 80 m/min cutting speed and 0.05 mm/rev feed rate. In addition, the lowest stress was 997 MPa at 80 m/min cutting speed and 0.05 mm/rev feed rate, the maximum stress was 1090 MPa at 40 m/min cutting speed and 0.15 mm/rev feed rate. It has been observed that the cutting force and the stress value show a similar tendency depending on the cutting parameters
