The Wear of Al₂O₃-Based Ceramic Cutting Tool in High-Speed Face Milling of AISI H13 Steel

Abstract:

In the present study, high-speed and ultra-high-speed face milling of AISI H13 steel (4647 HRC) was conducted in order to acquire a thorough understanding of the Al₂O₃-based micro-nanocomopsite ceramic cutting tool AWT10 wear mechanisms in high-speed hard milling. For different cutting speeds, the typical tool wear mechanisms is analyzed and compared. The analysis of the tool wear show that abrasive wear, adhesive wear, spalling and breakage are the primary wear mechanisms of AWT10 when cutting speed reaches 3000m/min. Micro-nanocomposite ceramic material AWT10 has favorable property of shock resistance. Improved cutting speed is in favor of cutting force reduction.
