Modern milling machines look much the same as they did 30 years ago. However, they now must cut superalloys, titanium, and high-tensile steels to closer tolerances and at faster rates than before. To ...

Hellers new uP-Gear technology is a flexible alternative to standard hobbing processes for large gears. The patent-pending uP-Gear process — co-developed by Heller Machine Tools and Voith Turbo — is ...

, '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 ...

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 ...

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.

A milling machine with over 15,000 hours is still grinding pavements across the fruited plain, and the men who manage it are determined to keep it going. Now, instead of it becoming a museum piece – ...

Some spare time recently got used-up designing a pair of involute gears – which, it transpires, is easy in principle, once certain almost-impossible-to-obtain facts have been gathered. There are ...
