Popis: This paper presents a method of determining the dynamic shear stress in metal cutting that considers the effect of the indentation force, and the tool flank-and crater-wear. The experimentally measured cutting forces must be corrected in order to assess those that are applied on the rake face and contribute to chip formation. Then, the indentation force and the forces applied on the clearance face, when significant flank wear is present, must be determined. Allowance must be made for crater wear, since this promotes an increase in the effective side-rake angle and consequently a diminution of the measured cutting forces. If the described effects are not taken into consideration, misleading values can be found for the dynamic shear stress.
