Optimization of the Gear Profile Grinding Process ...
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 it is difficult to find out what leads to grinding burn occurring only locally on the tooth flank.
