The prior release did not take the K Factor into consideration when generating Gleason style bevel gears having pinion tooth counts between 13 and 24 teeth.
A fix for that issue is now in place. Published circular thickness factor (K) figures have been subject to regression analysis and modelled as a series of polynomial expressions that provide good fit when compared with the original data. The pinion tooth count and ratio of pinion teeth / gear teeth are used with the polynomial expression to calculate the required K factor.
