Research on the Cutting Property of Ceramic Tool Cutting Nickel Based Superalloy GH4169

Abstract:

This paper will use the Al₂O₃-SiC_w whisker toughening ceramic tool WG300 and Si₃N₄-Al₂O₃ (Sialon) SX9 ceramic tool cutting performance test.Study on different cutting speed, ceramic cutting tool in machining nickel based high-temperature alloy tool life and tool wear mechanism, and analysis of the wear form under different cutting parameters. The test results show that: with the increase of the cutting speed, WG300 and SX9 two kinds of tool durability showed a downward trend, the value of VB is higher than that of Al₂O₃-SiC_w whisker reinforced ceramic cutting tool flank wear of Sialon ceramic cutting tool, but its notch wear value VN is far less than Al₂O₃-SiC_w whisker reinforced ceramic cutting tool,the main failure form of WG300 notch wear, the main failure form of SX9 for the flank wear.
