The crater wear generally is measured at a distance of half the depth of cut from the tool nose while machining materials like steel.But in machining materials like Ti-6Al-4V,the crater wear is not only intensive but also irregular in depth with adherent deposits of work material.
This requires scanning of the entire crater area to characterise crater wear.In the present study,the crater depth has been measured using Taylor Hobson NCS Profilometer.Fig.3 schematically shows the scanning of the crater area.
The crater areas on the tool thus scanned were mapped in
2D and 3D on computer using Taly lltra software.Fig.4shows one such mapping.The profile and the maximum crater depth were obtained from the 2D mappings.
Fig.5(a–e) show the measured depth of the crater,KT and the corresponding crater profile at different machining intervals at cutting velocity – feed combination of 85 m/min–0.20 mm/rev under all machining environments.
