Dataset on identification and correlation of secondary carbides on microstructure, wear mechanism, and tool performance for different cermet grades during high-speed dry finish turning of AISI 304 stainless steel
The aim of this study is to utilize reverse engineering approach for the identification of the elements and phases available on the commercial CERMET inserts with the help of characterization techniques such as Scanning Electron Microscope (SEM), Energy-dispersive X-ray spectroscopy (EDS), and X-Ray Deposition (XRD). Four commercial CERMET inserts were investigated in this research work and the effect of the composition and phases are related to it’s tool wear mechanism and performance. Each CERMET insert is used to perform a turning process on a CNC lathe for machining stainless steel (SS) under dry condition at a fix cutting length interval. Once it completes machining for a fix cutting length, the CERMET insert is taken out to investigate its wear mechanism with the help of SEM, EDS, XRD and using focus-variation microscope (Alicona). A correlation study is performed to relate progressive tool wear mechanism with elements and their relevant phases of various carbides. The approach of corelating wear property with the phase content will contribute for understanding of the wear mechanism under such extreme machining conditions. It will serve as a reference for the improvement of the performance of these CERMET inserts for such harsh machining condition by development of protective coatings for these CERMET inserts based on the identification of the composition and phases that improves tool life and reduces wear.
