Abstract:The present work is a fulfilment study on previous contribution presented by Mokas et al (2018) through investigation on the effect of chisel wear on the machinability of hardened C22 steel under drilling operations using twist high-speed steel (HSS) grade drill bits. Therefore, the evolution of wear in twist drill bits with respect to both flank and chisel edges has been reconsidered in order to sort out the most dominant wear rate in drill edges. Experimental investigation has been conducted on annealed and … Show more
