Abstract

The results from an international gear measurement 'round robin', which included Japan, China, France, Germany, USA and the UK, are presented. The work involved National Laboratories and other centres of excellence for gear measurement. Comparisons are made with survey results from the USA and UK. The measurement uncertainty requirements of National Laboratories are considered and compared with the Round Robin results. 1 Introduction Improvements in gear manufacturing accuracy are needed because they are required to transmit more power and to reduce noise generated during use. Significant improvements in the accuracy capability of gear machine tools and in the inspection machines, which verify the accuracy of these gears, has taken place in o
