Cutting Performance of TiB₂/WC/h-BN Micro/nano Composite Gradient Self-Lubricating Ceramic Tool when Machining Carbon Steel

Abstract:

Continuous cutting experiments of steel 45 were conducted to investigate cutting performance of TiB₂/WC/h-BN micro/nano composite gradient self-lubricating ceramic tool. Influences of cutting speed on flank wear and tool life were analyzed. The results show that flank wear increases slightly when cutting speed V≥80 m/min, tool life increases initially and then decreases with increasing cutting speed. Wear mechanism was studied: the primary pattern of tool wear is abrasive wear and adhesive wear and solid-lubricants in tool have a noticeable wear-resistance effect during machining.
