Geometric error analysis and compensation for multi-axis spiral bevel
The kinematic structure of 6-axis grinding machines for spiral bevel gears is similar to traditional multi-axis machine tools for metal cutting. Therefore, it is reasonable to compensate the 6-axis grinding machine using the modeling and compensation algorithm of traditional five-axis machine tools.

technical Rules for Optimal Basic Design of Bevel Gears
The most important influences of an increased whole depth are summarized in Figure 10. Usual limits for bevel and hypoid gears are a minimal whole depth of 0.8* module and a maxi-mal whole depth of 1.2* module. Cutter radius. A small cutter radius increases the contact ratio of a bevel and hypoid gearset.

Influence of the manufacturing method on the running behavior of
Beveloid gears, also known as conical involute gears, gain more and more importance in industrial practice. They are based on cylindrical gears, but have a variable profile shift along their tooth width. For some time, beveloid gears have been applied to marine transmissions (Winkler 2002; Zhu et al. in Chin J Mech Eng 25:328–337, 2012), …
