The Anatomical Record, EarlyView.Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Wear Mechanism of Multi-layer AlCrWN/AlCrWSiN Coatings on Cemented Carbide Tool Prepared by Arc Ion Plating in Dry Cutting of Sintered Steel [PDF]
MATEC Web of Conferences, 2019 To clarify the effectiveness of multi-layer AlCrWN/AlCrWSiN-coated cemented carbide tools, the wear progress was investigated in cutting sintered steel using three types of coated tool. Tool I had a mono-layer (Al60,Cr25,W15)N-coating film, Tool II had a

Laser surface texturing of a WC-CoNi cemented carbide grade: surface topography design for honing application [PDF]
, 2018 Abrasive effectiveness of composite-like honing stones is related to the intrinsic surface topography resulting from the cubic boron nitride (CBN) grains protruding out of the metallic matrix.

The Anatomical Record, EarlyView.Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

A New Mathematical Model for Flank Wear Prediction Using Functional Data Analysis Methodology
Advances in Materials Science and Engineering, 2014 This paper presents a new approach improving the reliability of flank wear prediction during the end milling process. In the present work, prediction of flank wear has been achieved by using cutting parameters and force signals as the sensitive carriers ...
