Flank Wear Model of Cutting Tools Using Control Theory

open access: yes, 1978
A model of the flank wear of cutting tools is developed by using linear control theory. The flank wear is assumed to consist of a mechanically activated and a thermally activated component. The wear process is mathematically treated as a feedback process,

Performance and wear mechanisms of PCD and pcBN cutting tools during machining titanium alloy Ti6Al4V

open access: yes, 2020
The need for increased productivity in difficult-to-machine titanium alloys has pushed manufacturers to examine the potential of ultrahard cutting tool materials such as polycrystalline diamond and polycrystalline cubic boron nitride as alternative ...

AN URBAN MARKETPLACE UNDER PRESSURE: The Steady Gentrification Process of Porta Palazzo (Turin) Through the Eyes of Market Sellers and Policy Makers

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Marketplaces, crucial sites for low‐income populations as sources of affordable goods and social interaction, are at a critical juncture. They are experiencing decline due to the rise of shopping centres and neglect by public authorities, while at the same time being rediscovered as tourist attractions, sources of profit and tools for urban ...

An investigation into tapping of Al6061/SiC metal matrix composite with straight flute HSS machine tap

open access: yesJournal of Mechanical Engineering and Sciences, 2019
The present study deals with tapping of Al6061/SiC metal matrix composite. Stir casting technique was used for the fabrication of composite. Castings were produced by varying weight percentages of SiC (5%, 7.5% and 10%) of 23μm size in Al6061.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Effect of Social Rank on Gut Microbes and Their Metabolites of Greater Long‐Tailed Hamsters (Tscherskia triton)

open access: yesIntegrative Zoology, EarlyView.
Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

Tool-wear analysis in cryogenic machining of NiTi shape memory alloys: A comparison of tool-wear performance with dry and MQL machining

open access: yes, 2013
Extremely high tool-wear rate in machining of NiTi shape memory alloys (SMAs) is one of the major reasons for limiting the use of conventional machining processes on NiTi.
