Kinematic analysis of the cutting speed for continuous generating grinding

Abstract

Due to its high productivity, continuous generating grinding is a popular finishing process for gears with small and middle sized modulus. However, concerning the complex temporally and locally changing contact conditions and their influence on the ground gear only restricted knowledge is available. In this study, theoretical investigations are conducted to identify the influence of tool and workpiece setting on the resulting cutting speed in the contact zone for continuous generating grinding especially with a higher number of starts. Depending on the geometrical setting of the gear and grinding worm, the resulting cutting speed can be higher or lower than the set tool circumferential speed. A comparable consideration for the dressing process and the resulting dressing speed ratio can be made.
