Abstract

In order to optimize efficiency of machining, surface properties and strength of machined parts, the complex relationships between machining parameters, elementary mechanisms of material removal and strength-controlling surface effects have to be understood. The results of the investigations allow to separate the effects of damage processes and macroscopic residual stresses on the strength of ceramics, and therefore to optimize the machining parameters. Cases of lapping and grinding are shown, where on one hand surface damage (Al2O3, SiSiC, SiC and Si3N4), and on the other hand residual stresses (ZrO2) are the dominating effects on the bending strength.
