Webfirst step in establishing the cutting force is to determine the cut length area. The area to be cut is found by multiplying the length of cut by stock thickness. Formula for calculating … WebForce Required in Cutting Operations: The force required to cut the blank can be determined by the area subjected to shear stress multiplied by the ultimate shear strength of the metal being cut. The blanking force maybe calculated by following formula: F = K x Q c t x τ Uultimate ADVERTISEMENTS: Where; F = Blanking force required.

WebIt is logical that the cutting force increases as the depth of cut increases and rake angle decreases. Deeper cuts remove more material, thus requiring a higher cutting force. As the rake angle, α, decreases, the shear angle, φ , decreases [see Eqs. (21.4) and (21.5) on p. 570], and hence shear energy dissipation and cutting forces increase. 15.
