NOTE: The diagrams above are used to determine the drive power, feed force, and torque. They are based on cutting force measurement in tempered steels in Cgr. 6. Tensile strength: Rm = 600 N/mm2. The base cutting speed used is: vc = 80 m/min. TDMX • Regrinding Length • FPE(M) • Metric TDMX • Regrinding Length • PK(M) • Metric
