...H. Ji; J. Chua; H.-Y. Hsu; A. B. Wedding In recent years, downscaled coordinate measuring machines (CMMs) are in demand and bring challenges to the development of micro/nanoscale probes for a variety of microscale structure measurement applications. A working prototype apparatus is developed...

.... Next, the large-sized spiral bevel gears are manufactured and the tooth contact pattern of these gears is investigated experimentally. Moreover, the real tooth surfaces are measured using a coordinate measuring machine and the tooth flank form errors are detected using the measured coordinates...

... contact pattern of existing gear sets. Test gear sets are measured using a coordinate measurement machine prior to a special lapping cycle where the position of the gear sets on the lapper does not change, and then are remeasured after lapping in order to establish how much and where material was removed...

...Chensong Dong; Chuck Zhang; Ben Wang; Guoxiong Zhang Coordinate measuring machines (CMMs) are already widely utilized as measuring tools in the modern manufacturing industry. Fast and accurate probing is the current trend for the next generation of CMMs. However, measuring velocity of CMM...
