The teeth of teeth of involute gears hobs and teeth for involute spline shaft hobs have a trapezoidal profile. In the U.S. a huge volume of good quality hobs are produced, and offers potential for ...

, 'involute gears' and 'cycloid gears', based on the difference in tooth shape. Both types have their own advantages, but technology blogger lcamtuf explains the advantages of involute gears. A ...

Invention of the gear-hobbing process about 150 years ago revolutionized not only gear fabrication, but also gear design. Basically, a hob or shaper cutter traverses the gear blank to generate teeth.

If you’re into CNC machining, mechanical tinkering, or just love a good engineering rabbit hole, you’re in for a treat. Substack’s [lcamtuf] has written a quick yet insightful 15-minute introduction ...

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.
