Beschreibung

Grinding is one of the last manufacturing steps in the production chain of modern workpieces. Thus, product quality is more important compared to the productivity and is therefore the limiting factor. Exemplarily, thermal load due to the grinding process leads to thermal induced damage such as grinding burn or tensile residual stresses. Previous studies showed the capability of grinding wheels with mechanically induced patterns to reduce the thermal load on a workpiece throughout the grinding process. In this paper the patterning tool is investigated in regard to the grade of CVD thick layer diamond (CVD-D). In detail, three CVD-D grades are investigated in terms of their features and their wear mechanisms. SEM and X-Ray diffractometry as well as Raman measurements are conducted. A wear mechanism of surface fatigue is found to be dominant. Pole figures as well as the microscopic measurements indicate a correlation between the texture of the CVD-D grade and the wear extension.
