STUDY OF GEAR PROFILE SUBMITTED BY SREERAJ.M.R VISHNU.M.S VISHNU.V UNDER THE GUIDANCE OF Mr.P.MOHAN (M.E)

ABSTRACT : 

ABSTRACT Hobbing is a machining process for making gears, splines,and sprockets on a hobbing machine, which is a specialtype 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 other gear forming processes it is relatively inexpensive but still quite accurate, thus it is used for a broad range of parts and quantities. It is the most widely used gear cutting process for creating spur and helical gears and more gears are cut by hobbing than any otherprocess since it is relatively quick and inexpensive.

INTRODUCTION : 

INTRODUCTION Hobbing is a machining process for making gears, splines. Many manufacturing firms that maintain museums of how products were produced in times past will have examples of manual gear hobs that helped to produce gears prior to the gears of the 19th century and earlier. Along with these completely manual gear hobs will be samples of some of the first semi-automated gear hobs, and finally examples of more recent technology that demonstrates the fully automated process that modern gear hobs use to produce gears today. A few producers of gear hobs also have interesting literature on the history of gear hobs, including details about how modern gear hobs can produce thousands of gears in a single hour.
