Cutting force calculate

Punching force is the total force required by the machine to punch a particular hole based on the material thickness, type and hole shape. Calculating the punching force is very important for checking whether the machine has enough tonnage to do the job without damaging the machine itself. This is especially true if a large tool is used in thicker material or harder materials such as stainless steel. The most common formula to determine the punching tool is by multiplying the material shear strength with the material thickness and the perimeter of the punch tool

Shear and tensile strengths for most materials are not the same. Shear strength for:
Aluminum is approximately 50% of its tensile strength
Cold roll steel is approximately 80% of its tensile strength
Stainless steel is approximately 90% of its tensile strength


This App Moto is to avoid the breakage of cutting elements and mechanical joints in the shearing machine
