In this
method of hobbing, the hob feeds radially to depth at a controlled
rate per revolution of the component. When producing wormwheels this
motion is all that is necessary and the work is finished once the
hob reaches full depth. It is also useful when the approach distance
required by axial hobbing is limited.
Hob path :- (see diagram)
1) traverse in:- to clear of component.
2) feed in:- to required depth.
3) traverse out:- clear of component.
