TL;DR: In this article, the authors investigated how and why TiN coatings modify the performance of high speed steel cutting tools and concluded that a unique combination of sufficient adhesion to the substrate, high hot hardness, high wear resistance and an ability to improve the contact conditions at the cutting edge is the answer.

TL;DR: In this article, a new numerical simulation model for two-body abrasion has been proposed, which preserves the simplicity of the classical model but increases its versatility by treating the case of multiple abrasive groovings in a surface of realistic topography.

TL;DR: In this paper, the friction and sliding wear characteristics have been investigated for one conventional and one powder metallurgical high speed steel (HSS) in both the TiN-coated and the uncoated condition.

TL;DR: In this article, four principally different dead zones are defined based on the localization of the two separating cracks that form the chip back and the cut surface, respectively, which may influence tool life, roughness of the cut surfaces and the dimensional accuracy of the workpiece.

TL;DR: In this article, a numerical model for abrasive wear has been developed which provides a correlation between the resulting surface topography and the groove sizes of individual grooving events, and numerical examples are given for the different geometries of the abrading tip.
