Determine the spindle speed (rpm), the feed rate (in/min) and the cutting power required for turning a 1º diameter copper rod with a depth of cut of 0.1" using a cemented carbide tool.
O N=287 RPM, F-25.8 in/min, P=9.7 hp
ON=2866 RPM, F=258 in/min, P=97 hp
ON=1146 RPM, F-25.8 in/min, P=97 hp
O N= 11460 RPM, F-340 in/min, P=130 hp
ON= 1146 RPM, F-34 inimin, P= 13 hp
ON= 115 RPM, F-3.4 in/min, P=1.3 hp
QUESTION 6
It is required to face mill an aluminum block to size it down from 2" to 1.5" thick using a 3" diameter 2-toothed carbide cutting tool. The block is 6.0" wide and 6" long. The entire tool diameter
engages the workpiece during the cut.
Calculate the recommended spindle speed in revolutions per minute, feed per tooth, and cutting power required.
O N=1529 RPM, f= 0.026 in/rev/tooth, P = 36 hp
O N-3820 RPM, f= 26 in/revitooth, P=27 hp
O N-3820 RPM, f= 0.052 in/rew/tooth, P=27 hp
ON-382 RPM, F= 0.026 in/revitooth, P = 0.027 hp
O N-3820 RPM, f= 0.052 in/rev/tooth, P=2.7 hp
O N-382 RPM, F= 0.052 in/rev/tooth, P = 0.027 hp
