Influence of Tool Specification and Machining Parameters on the Wear Behaviour at Generating Gear Grinding

Abstract

One research objective for generating gear grinding is to increase economic efficiency and productivity of the process. At the same time gear quality must be equal or higher. In addition to machining parameters, tool specification has a significant influence on process productivity, workpiece quality and the wear of the tool itself. Due to the variety of tool specifications process users have the problem of selecting the best fitting tool for their demands. Therefore, it is necessary to know how interactions of tool specification and machining parameters influence tool wear and workpiece quality. But basic experimental studies, which take different tool specifications into account, are missing today.This paper focuses on the influence of different tool specifications and machining parameters on the tool wear for generating gear grinding. With analogy trials the influence of different specifications and machining parameters on tool wear and the process is mapped. The results are analyzed, discussed and summarized in a model. Furthermore, the applicability of the findings based on analogy trials to generating gear grinding is validated.
