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 ...

Wear Characteristics of Ceramic Tools When Turning BN Free-Machining Steel

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2013
This study examined the wear characteristics of ceramic tools when turning BN free-machining steel based on AISI 1045. An experiment was conducted to investigate why the alumina TiC-based ceramic tool showed remarkably better cutting performance than a ...

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

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Comparative performance analysis of Tung and Jatropha emulsions for development as cutting fluids

Materials Research Express, 2019
This work was based on a comparative analysis of the action of Tung and Jatropha Curcas emulsions as cutting fluids for a CGI gray cast iron, where machining parameters, tool wear and fluid efficiency were analyzed. The results that followed the Reichert

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.
