A comparative study of the effect of tool geometry with negative SCEAs on machining parameters

Bar diameter as an influencing factor on temperature in turning

“…Cutting the smallest bar diameter of 31 mm led to the highest tool temperature and with the largest bar diameter of 75 mm to the lowest tool temperature. As mentioned earlier, the fact that the higher the cutting speed the higher the temperature has been known since the work of Taylor in 1907 [24] and as demonstrated by Nouari et al [25] and Kattan et al [26]. This was clearly shown in Fig.…”

Analysis of an equivalent tool face for the cutting speed range prediction of complex grooved tools

“…(13) considers a tool face without chip breaker. For inserts with chip breaker, according to some authors [14,[25][26][27] and considering some experimental wear results [4,25], it is assumed that the chip is acting on both a primary and secondary contact zone, as shown in Fig. 3b.…”
