On the honed cutting edge and its side effects during orthogonal turning operations of AISI1045 with coated WC-Co inserts

摘要

The design of the cutting tool microgeometry influences the thermo-mechanical load profile on the wedge. Applying the appropriate hone design stabilizes the cutting edge, leads to improved wear behavior and higher tool life. Higher process forces and temperature, induced by larger hone, can be described as a side effect of cutting edge preparation, which should also be observed. This paper presents the quality oriented cutting edge preparation via abrasive brushing. The influence of the hone design on process forces, wear behavior and tool life of coated inserts will be analyzed within a wide range of cutting edge microgeometries and process parameters.
