Over the past few years there has been a shiſt in the gear-milling industry. Automo- tive manufacturers are moving away from solid HSS tools and replacing them with indexable-insert tools. Te result is higher productivity, increased tool life and the elimination of regrinding and recoating. Te change has primarily taken place in the global market for commercial vehicles, including trucks and agricultural machines, and yellow goods such as earthmoving and construction vehicles. Te improve- ments are extraordinary. Tings that were impossible 18 months ago are now performed on a daily basis. Te gear-milling revolution, however, began several years ago. In 2005, there was a call for a change in the performance of machines in the gear-milling indus-

try. Te automotive industry itself was experiencing drastic changes in demands, as efficiency became more important to streamline production. Now more than ever for automotive, maximum productivity is a high priority. More gears are being produced than ever before due to expanding gearboxes and shrinking engines that allow for better emission control and fuel economy.
