Research has shown that the performance of different grinding wheels can change significantly and that improvements in cutting oil delivery can be identified.
The research has been part of a project entitled "Reducing gear grinding costs for generative gear grinding" carried out by the Gear Research Foundation.
The Gear Research Foundation, a subsidiary of the British Gear Association, has successfully completed a programme of research into reducing gear grinding costs and results were reported to a GRF technology transfer day at ALSTOM, Rugby.
In addition to performance differences, the research determined the wheel wear and grinding burn limits for both roughing and finish grinding. A major research programme to investigate many aspects of micro-pitting in gears is about to start.
The research also identified improvements in cutting oil delivery and has developed a calculation procedure for optimising grinding feed and speed to achieve high metal removal rates without grinding burns yet maintaining excellent accuracy.
A computer programme for this calculation procedure is being made available to the collaborating companies. A follow-on project will investigate the improvement in form grinding as well as the control of grinding burn and wheel wear in this process.
The Gear Research Foundation is currently funding research into gear lubrication (micro-EHL), material fatigue strength, precision forging, gear stress analysis and worm gear performance.
The GRF has completed four major research programmes related to mechanical power transmission and further work is planned in this area to improve the technological base and competitiveness of member companies. Membership has grown from the ten founder businesses in 1993 to the current number of 34 significant companies and several newmembers are expected to join soon.
