Machinability and tool wear studies on AZ91/B4C metal matrix composites using uncoated and CVD diamond coated WC-Co turning inserts
Source abstract
Abstract
AZ91/B 4 C metal matrix composites (MMCs) comprising three different amounts of B 4 C particulates, 12, 18, and 24 wt% were fabricated using a melt stirring-squeeze casting technique. Machinability studies were conducted on the cast composites using uncoated and CVD diamond coated WC-Co turning inserts. The tool life of these turning inserts was calculated at different cutting speeds of 30, 60, and 90 m/min. Results revealed that with the increasing cutting speed, the surface roughness of the MMCs decreased and the magnitude of the main cutting forces increased. The increased magnitude in the cutting speed and particle proportion significantly reduced the tool life. The abrasive action of the hard B 4C particles caused severe tool wear during the machining of AZ91–12%B 4C, AZ91–18%B 4C, and AZ91–24%B 4 C composite materials. From the tool flank wear results, it was evident that diamond coated inserts outperformed uncoated WC-Co inserts at all machining conditions. The tool life of the CVD diamond coated insert at the cutting speed of 30 m/min was found to be the highest.
