Ceramic tool wear when machining austempered ductile iron

Commercially available cutting tool inserts (Al sub 2 O sub 3 , Al sub 2 O sub 3 :TiC, Al sub 2 O sub 3 :SiC sub / w /, and SiAlON) were used to turn heat-treated spheroidal graphite Fe at speeds of 150-450 m min sup - sup 1 . Flank wear was the most common cause of tool rejection, although tool fra...

Zusammenfassung:Commercially available cutting tool inserts (Al sub 2 O sub 3 , Al sub 2 O sub 3 :TiC, Al sub 2 O sub 3 :SiC sub / w /, and SiAlON) were used to turn heat-treated spheroidal graphite Fe at speeds of 150-450 m min sup - sup 1 . Flank wear was the most common cause of tool rejection, although tool fracture occurred when machining the austempered Fe at the highest speed.
