Introduction
Hydrophobicity is the physical property of a molecule that is repelled from a mass of water. Super-hydrophobic surfaces, such as the leaves of the lotus plant, are those that are extremely difficult to wet. The contact angles of a water droplet exceeds 150°and the roll-off angle is less than 10°.

Performance
Reduction of cycle time : Assist high speed cutting by incerased of Hob tooth
Reduction of cutting wear : Reduced hob tooth Flank wear and overland because of double hob cutting edgh than a conventional Hob
Saving cost : Increased Productivity by increased tool life
Use
It will be most effective if you cut big module gears

charcterstics:
1.high cutting speed
2.short machining speed.
3.a longer tool life than conventional hss cutters.
4.time saving per price for gear manufacture.

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

A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear.[1] Two or more gears working in a

Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets on a hobbing machine, which is a special type of milling machine. The teeth or splines are progressively cut into the workpiece by a series of cuts made by a cutting tool called a hob. Compared to
