Dressing of vitrified bonded CBN tools for continuous generating grinding

摘要

Profile accuracy, high surface quality and compressive residual stress in the tooth root and flank are necessary for a high durability of heavy stressed gears. This article shows the advantages of vitrified bonded cubic boron nitride (CBN) tools in comparison to corundum tools relating producible compressive residual stress. In this context, especially the relationship between the dressing strategy for vitrified CBN tools and the workpiece surface and subsurface was investigated in detail.
