PROJECT 4

Generative Gear Grinding cost reduction

This programme of research, supported by the DTI and The Institute of Grinding, has been successfully completed and the results reported at a technology transfer seminar.

The research revealed significant differences in performance between various grinding wheels and determined both the wheel wear and grinding burn limit for roughing and finish grinding. Improvements were identified in cutting oil delivery and developed a calculation procedure for optimising grinding feed and speed rates to achieve high metal removal rates without grinding burns, while maintaining excellent accuracy.

A follow-on project will investigate the improvement in Form Grinding, in particular the control of grinding burn and wheel wear in this process. This work has wide implications to the majority of high performance gears being manufactured today.
