Abstract
This experimental study deals with the effect of machine structural loop st iffness on grinding of ceramics. The objective of the study is to investiga te how the loop stiffness affects grinding forces, wheel actual depth of cu t (ADOC) and workpiece strength. A compliant workholder is specifically des igned and attached to a precision grinder to simulate grinding machines of various compliances so that the effect of machine loop stiffness can be iso lated under otherwise identical conditions. Silicon nitride is used as work piece material and ground with diamond wheels of two bond types and three g rit sizes at machine loop stiffness of four different levels. The ground wo rkpieces are assessed in terms of residual workpiece strength, grinding dam age, grinding forces, and ADOC. Theoretical analyses are given to indicate that machine loop stiffness can affect on normal grinding forces and workpi ece strength. A discussion is provided to reveal how residual workpiece str ength is affected by residual stress and grinding-induced damage.
