Cutting Teeth in Bevel Gear
The illustration on this page shows a milling machine set up for cutting the teeth of a bevel gear.
The gear is held in place by a split bushing that is expanded in the hole. The spiral head is elevated to the proper cutting angle and the table is fed longitudinally from left to right.
In setting off centre to trim the sides of the teeth to the proper thickness, the table is adjusted the required amount on the knee and then the blank is rotated by means of the index crank, as previously explained.
