Definition of adhesive wear in industrial cutting: loss of knife material when micro-welds between the edge and the substrate fracture at the knife side, not the substrate side.

Definition of AlCrN (Aluminium Chromium Nitride) PVD coating for industrial blades: the hardest standard PVD coating, ideal for high-temperature and dry cutting applications.

Definition of built-up edge (BUE) in industrial cutting: weld-like adhesion of substrate material to the cutting edge, a common cause of poor cut quality on stainless, aluminium and gummy plastics.

Definition of burr in industrial cutting: the unwanted projection of material on the cut edge, how it is measured, what causes it, and how to minimise it on slitter, shear and granulator blades.

Definition of chipping in industrial cutting: small fragments breaking off the cutting edge, the four root causes, and how edge hone, hardness and impact load determine chipping resistance.

Definition of clearance angle (also called relief angle) in industrial cutting: the angle of the back face behind the cutting edge, the substrate-by-substrate range, and how it interacts with hone and burr.
