An important element of the gear hob design is the tip relief which represents a relief of the tooth profile and a part of the Archimedean spiral. The Archimedean spiral is a curve traced out by a point moving...

Gear dry grinding is the new state-of-the-art process for gear manufacturing. Thanks to the elimination of cutting oils during the process, gear dry grinding has marked an important breakthrough.

A gear hob is a gear cutting tool composed of different parts. The main parameter characterizing a gear hob is the module, which is the result of the division between the pitch gear diameter and the number of the...
