AMMAN-JORDAN ace milling operation is performed to finisth the rface of a steel nectanguliar workgiece 14.0 inl 5.0 in wide toeth (ementied carbide inserts) and a 4.0 in diameter. Cut ditions are: v- 600 ft/min, f-0010 in hoodh, and d-0150 in. Detemmine the folliowing The milling outter has four The time to make one pass across the surface 9.43 min The metal removal rate during the cut 10.3 in/min b 0858 inn2743im 20.5 min 1.7 mi d. 0.78 min C. d229 inmin rilling operation is to be performed with a 25.4 m dameter twist drill in a steel workpart.
