A unified approach to traverse dressing with radiused diamond tools

An investigation is made into traverse diamond dressing of grinding wheels using radiused dressers. Previous methods have modeled dressing using an equivalent diamond-contact width. This method contains inherent problems, particularly with overlap ratio and dressing depth. In this study, the geometry is modeled as a series of scallops. Dressing sharpness is quantified using the concept of Aggressiveness, which unifies numerous disparate parameters into a single dimensionless parameter. Experiments show that this single parameter accurately quantifies dressing sharpness for radiused, rotary, traverse-disc dressing. Also, the concepts of minimum achievable specific energy and the transient nature of wheel sharpness are investigated.
