Determination of specific cutting force components and exponents when applying high feed rates

Achieving (assuring) high productivity machining contributes to the ongoing development of efficient material removal, which can be expressed with material removal rate (Qw) and surface rate (Aw) (parameters. The values of these parameters increase in the case of a constant depth of cut if the value of cutting speed and the feed rate increase. Choosing more intensive cutting data usually associated with an increase in cutting forces. The increase in force has an impact on the workload and tool life of the Workpiece-Fixture-Machine Tool-Cutting Tool (WFMC) system. Therefore, in applying the Kienzle and Viktor relationship to calculation of the cutting force, we need to know the change in the specific cutting force (kc1.1) and the exponent related to it (z) in cases where a much higher feed rate than usual is used. To determine this, turning examinations were carried out with increased feed rates. Our aim was to determine the specific cutting force components (kc1.1, kp1.1, kf1.1) and the exponents (zc, zp, zf) belonging to them at turning with high feed rates for a steel workpiece.
