Meltham Mills Engineering (MME) now takes only eight minutes to inspect every critical feature on a typical gear component, compared to four hours previously – 30 times faster. Simultaneously, data is gathered on the form of features, the first time MME has had this automated capability. This has been made possible using Renishaw's SP25 scanning probe fitted to a new Mitutoyo Crysta co ...

Tagliabue[9] presented a case study on " Influence of Carburizing and Nit riding on failure of gear" To this aim particular case of failure analysis of a pinion gear is considered. It was built in 18 Ni Ci case carburized quench hardened and tempered steel. BY very few working cycles the transmission gear permanently failed.
