gear-generating method
Quick Summary
The gear-generating method is a primary technique for machining gears, especially for mass production. This method relies on the principle that two involute gears, or a gear and a rack, with the same diametral pitch will mesh correctly.1
In this process, a cutting tool shaped like a gear or rack is used to cut teeth into a gear blank. Machines employing this method include gear shapers, which use reciprocating strokes, and gear-hobbing machines. Gear hobbing utilizes a rotating, multi-tooth cutter called a hob to continuously generate teeth on various gear types, offering high accuracy and production rates. This contrasts with form cutting, where the tool's shape matches the space between teeth, and template cutting, which uses a template to guide the cutter.1
