the teeth and body are assembled separately and with different materials.
advantages:-
1.the cutting control is efficient controlled relief life.
2.cost effective with lower material price for body.
3.useful for high speed cutting with controlled arbor.
disadvantages:-
1.the manufacturing process is complex
2.the out-parameter
-
increasing productivity:special hss and multi layer coating increasing cutting ability more than 2 times compared to convential hob.
cost savings:increase tool life and reduced cycle time lead to cost saving efficiencly.
friendly to environment:production without cutting oil.
sucessful results require:need a good bobbing m/c for turbo

Traditionally, profile and lead inspections have been indispensable portions of a standard inspection of an involute gear. This also holds true for the worm of a worm gear drive (Ref. 1). But the inspection of the profile and the lead is rarely performed on a worm wheel. One of the main reasons is our inability to make good definitions of these
