Application of the tool-material pairing methodology
Machinability of difficult materials - Application to hardened steels

The aim of this study is to determine, as a function of cutting parameters and material hardness, the evolution of cutting force components:

• cutting force: F _c ;

• feed force: F _f ;

• penetration or thrust force: F _p .

The specific cutting force, also known as cutting pressure, must also be determined. This quantity is defined as the cutting force reduced to the cross-section of the undeformed chip:
