Abstract
High speed deep grinding has been studied to explore its effects on machining characteristics and surface integrity of yttria partially stabilized tetragonal zirconia. A grinding depth of cut of up to 1.5 mm, which is significant for ceramics grinding, was used to grind this ceramic material under a normal creep feed rate of 500 mm min(-1) using a resin bond diamond wheel. It was found that the increase in the grinding depth of cut from 0.1 to 1.5 mm greatly reduced the wheel wear and slightly improved the surface finish, but resulted in a slightly deeper subsurface damage layer. High wheel speeds reduced subsurface damage, but shortened wheel life. (C) 2002 Elsevier Science B.V. All rights reserved.
