What is Hob Resharpening and Accuracy Effects about?

This document discusses how inaccuracies in hob quality and resharpening can affect the accuracy of gears generated by hobs. It explains that modern CNC hobbing machines are capable of high accuracy but are still limited by the accuracy of the hob tool. High accuracy hobs are necessary to produce high accuracy gear profiles. The geometrical properties of involute worms, from which hobs are derived, must be well understood to avoid losing hob accuracy. Both the purchased accuracy of hobs and the resharpening
