In grinding, most control strategies are based on the spindle power measurement, but recently, acoustic emission has been widely used for wheel wear and gap elimination. This paper explores a potential use of acoustic emission (AE) to detect workpiece lobes. This was achieved by sectioning and analysing the AE signal in the frequency domain. For the first time, the profile of the …

Profile Grinding The main difference between gear profile grinding and standard grinding is the varying pro-file angle ϕ along the tooth flank. Investigations of gear profile grinding can only show total effects over the whole profile height and varying grinding conditions. This is a major reason why
