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 ...

Distributed machining control and monitoring using smart sensors/actuators [PDF]

, 2004
The study of smart sensors and actuators led, during the past few years, to the development of facilities which improve traditional sensors and actuators in a necessary way to automate production systems. In an other context, many studies are carried out

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.

Flank Wear Progress and Variation of Tool Forces

Journal of the Japan Society of Precision Engineering, 1963
The cutting mechanism under conditions of progressive flank wear was analyzed theoretically. General expressions for depth of cut and stock removal rate were derived, taking variation of tool forces into consideration.Ferritie nodular cast iron was machined with carbide and ceramic cutting tools, and variation of tool forces associated with progress of
