The Technology Shift - May 2014
The article "The Technology Shift" appeared in the May 2014 issue of Gear Technology.

This movement wasn't immediately realized in gear hobbing because coated PM-HSS hobs and complex gear profiles remained highly effective and productive methods. Only fairly recently have gear manufacturers started to take a serious look at indexable technology to cut gear teeth.
