Analytical model for revealing tool wear law during edge trimming of carbon fiber reinforced plastics composites

open access: yesFriction
This study proposes a novel tool wear model for the edge trimming process of carbon fiber-reinforced plasticities (CFRPs). The main innovation is that the model considers the actual wear state of both the planar flank face and the semicylindrical cutting

Effects of the size of built-up layer on the wear of cemented carbide tools in cutting of SUS304 stainless steel

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2021
Built-up layer (BUL) formed on the tool rake face during cutting has the tool protective effect. As BUL can change the shape of tool resulting in variation of rake angle and edge radius, it may have significant influences on the cutting phenomena such as

Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges

open access: yesAdvanced Science, EarlyView.
Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...

Mathematical models of flank wear using vibration amplitude ratio in drilling [PDF]

open access: yesFME Transactions, 2019
This paper presents a model for on-line prediction of a drill flank wear using changes in vibration amplitude in the drilling process. Prediction of wear-time and wear-amplitude ratio relationships during the drilling process is enabled by this ...

Evaluation of flank wear of a self-propelled rotary tool during turning using nanofluid under MQL [PDF]

open access: yesEPJ Web of Conferences
Inconel 718, a heat-resistant nickel alloy, is employed in aerospace, marine, and defence applications due to its unique properties. However, these alloys are difficult to cut due to their low heat conductivity and proclivity for work-hardening.

Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization

open access: yesAdvanced Science, EarlyView.
Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...

Study on the Wear Performance of Spiroid Worm Drive with Steel–Steel Meshing

open access: yesMachines
Worm drive belongs to the inclined plane transmission principle, and there is severe wear on the conjugate tooth surface. To reveal the wear mechanism and realize steel–steel meshing in the spiroid worm drive, the meshing performance model of conjugate ...

Long Sump Life Effects of a Naturally Aged Bio-Ester Oil Emulsion on Tool Wear in Finish Turning a Ni-Based Superalloy

open access: yesMetals, 2023
This paper discusses a method of finish turning Inconel 718 alloy to compare machining performance of a naturally aged and used metalworking fluid (MWF), which had been conventionally managed through its life cycle, with the same new unaged product.
