Empirical Formula 1. Clamping force (T) = Clamping Force Constant Kp * Product Projected Area S (CM * CM) * Safety Factor (1+10%) To properly calculate necessary clamp tonnage, you must first know the projected area of the molded part/s plus any runners. Area can be calculated by multiplying length times width, A = L x W or A=πr2.

The maximum force in the operation of grinding can be calculated by expression: F****max [kg] = a [mm2] * re [kg/mm2] * n A = area of material removed, re = specific resistance of cutting, and n = number of cutting teeth simultaneously. As the shape of the teeth varies, the value of A also varies and therefore the value of the force as well.
