Chip thickness equation
Web(b = chip width and t = chip thickness before removal from workpiece). Work done in shear (W) (portion of the work done in removing a chip consumed in shearing of the metal on the plane of the shear) can be calculated from the formula W S = S S [cos f + tan (f – α)] WebJul 1, 2014 · The following equation is used to calculate spindle speed: rpm = sfm ÷ diameter × 3.82, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and 3.82 is a constant that comes from an algebraic simplifica-tion of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π).
