Abstract
The heat generation during metal cutting processes affects materials properties and the tool wear. Knowledge of the ways in which the cutting conditions effect the temperature distribution is essential for the study of thermal effects on tool life. Analyses of three-dimensional transient temperature distributions in a metal cutting process using a finite element code the Deform 3-D was presented in this paper. The effects of the rake angle, cutting speed, feed rate, tool and workpiece materials on the temperature and heat flux are studied. The results show that increase in cutting speed and feed rate increases the cutting temperature while increasing rake angle reduces the cutting temperature. Results indicated that, as cutting speed increased from 103.2 to 250 m/min an increased in temperature equal to 21.9% occurred. With a reduction in rake angle from 5o to -5o, temperature increased by 12.3%. As the feed rate increases from 0.16 mm/rev to 0.25mm/rev, the temperature increases in a 13.82%.
