It refers to important elements: the speed at the insert edge removing • Work piece’ s rotation at a determined the material at the periphery of the speed of the spindle, “n” work piece. The cutting speed is • linear movement of the tool at a determined related to the diameter of the feed, “f” work piece. • Cut depth, ap F- Defined in mm/rev and it is the distance covered by the tool during every rotation of the work n aapp piece. “f”- refers to the distance DDiaamm. . covered by the tool in a one minute, that is the feed vf (mm/min) f -ap - Depth of Cut Cutting Parameters Formula The spindle speed n is the number of rotations the Volume “Qz”: Metal Removal Rate work piece rotates in one minute and it is indicated in This value takes into consideration Vc, Ap revolutions/minute. and feed to calculate the amount of material removed. The Surface Speed can be calculated with the following formula: Qz = Vc x f x ap (cm3/min) D=Diameter n=Spindle speed π=Constant Metric n Vc Vc = Dxπxn (m/min) 1000 D D=(mm) n=(revs/min) π=3.14 C194 www.kennametal.com
