How much the Actual Cutting Power is required when cutting 4140 by ASX445R10005D? With Depth of
Cut is 3mm, Cutting Width is 80mm, Cutting Speed is 220m/min, Feed per Tooth is 0.1mm/tooth, and
Machine Coefficient is 80%.
Select ASX445 from Cutter, 4140 from Work Material. Because of ASX445R10005D, input 100 in DC
and 5 in z column. According to each conditions, input 3 in ap, 80 in ae, 220 in vc, 0.1 in fz, and 0.8 in η.
Then press ＜Calculate＞ and PC=4.24 (kW) is obtained.
