Hard cutting force factors mainly include cutting speed, feed rate, cutting depth, flank wear and workpiece hardness. Research scholars indicate that the implementation of hard cutting on different levels of precision machine tools, cutting force does not change.
Dr. Brazil abraomendes pcbn tools were selected ceramic knives, low content and high cbn cbn cutting aisi52100 content bearing steel (hardness 62hrc) found: radial cutting force, followed by the main cutting force and the axial cutting force; roughing cutting about 6-9 times the force when finishing; cutting force and feed rate, depth of cut and flank wear to approximate linear relationship; when the cutting speed is increased, the cutting force decreased slightly. Germany RWTH Aachen University w. Professor konig pcbn by ceramic tool and cutting tool 100cr6 hardened bearing steel cutting force comparative experiment to study the cutting speed, depth of cut and feed rate of the cutting force of impact trend.
