Extract

Machined parts made of fine ceramics are usually finished by grinding (Yajima et al.,1990, Mishima et al.,1987). The residual stress introduced by grinding will influence the fracture strength and the function of ceramics, and needs further consideration. Over the past few years, a considerable number of studies have evaluated ground ceramics by means of the X-ray method. However, it is well known that X-ray stress measuring data, 2 θ φ φ-sin2 φ curves of the surface layer of the unidirectionally machined ceramics are showing non-linear behavior (Kishimoto et al.,1987) . In this case, the sin2 φ method is inadequate for the evaluation of the stress (Sasaki et al.,1989).
