Hobbing also simplifies gear design. Parameters such as diametral pitch or module, profile angle, addendum, whole depth, and fillet-radius proportions define the cutting edge of the hob, called ...

Following an earlier proposal for transcribing the angle of hob profile teeth measured in inches, our correspondent now describes how to execute a similar task with metric measurements: “The U.S.

When a job calls for designing nonstandard gearing, you might crunch through the AGMA or ISO calculations or turn to one of several gear-design programs.
