Question

Diffrence between cutting force and stripping force

Answer 1

Cutting is a process of extensive stresses and plastic deformations. The high compressive and frictional
contact stresses on the tool face result in a substantial cutting force F.
this force is in the direction of primary motion. The cutting force
constitutes about 70~80 % of the total force F and is used to calculate the power P
required to perform the machining operation.

Stripping means extracting the punch. A stripping force develops due to the spring back (or resiliency) of the punched material that grips the punch.Stripping force varies based on part material type and thickness as well.
