In today's automotive industry Benchmarking plays a vital role to improve performance, quality of critical functions and key areas of an organization by understanding and evaluating the products & processes in relation to Best Practices.
Gear Reverse Engineering (here in after called as GRE) a part of Benchmarking is an activity which follows an analytical approach to calculate basic key parameters for an unknown gear pair.
This paper propose a diagnostic tool/method, which determines basic gear parameters for an unknown gear pair, by simply measuring few dimensions as input followed by step wise analytical approach. This tool/method simplifies the gear designer job at initial stage by eliminating frequent trial & errors, iterations and complex measurements, which saves time & cost.
