Abstract: The performances of mixed
ceramic and sailon ceramic tools in machining nickel based alloy
are tested. The negative cutting edge inclination and small tool
lead angle are recommended for reducing ceramic tool failure. So
called "notching at depth of cut" is not actually at the depth
of cutting line, but out of cutting area. The real reason of
notching is caused by shocking of "sawtooth" on sawtooth-shaped
burr and fin-shaped edges of chip.
Key words:
Ceramic tool Nickel based alloy Notch wear Metal cutting
