Gear Manufacturing Process
Gear manufacturing is today a multi billion dollar industry. As the demands
of this industry is growing manufacturers are now increasingly seeking
machining tools and technology that can meet with the tough challenges. As
in this increasingly globalized world order manufacturers need suppliers
that has global resources for delivering state-of-the-art machines, tools
etc. Gears are now produced in near-net shape, with a cut in production as
well as labour costs and elimination or reduction of wastes. These are also
impacting the gear manufacturers to have greater freedom in the choice of
materials.

Steps in the
Manufacturing Process of Gears
The gear manufacturing process is a complex step right from selecting the
right material to finally doing the finishing process for getting an optimum
quality gear. Gear blanks in the beginning are first roughed out and
completely stress relieved this is done to minimise the distortion that have
taken place after carburising. The blanks subsequently then undergoes the
finishing process. Then the gear cutting process takes place giving
allowance on the tooth flank for grinding. Then subsequently grinding and
other steps takes place. Following are the steps in the gear manufacturing
processes:
Wire Cut EDM(Electro
Discharge Machine)
Wire-Cut EDM
The wire-cut produces gear shapes by cutting the metal gears with a
continuously moving wire. Which operates with rapid, repetitive discharges.
This process is used to cut gears that are very thick and intricate. In the
following image the gears are machined into two pieces by using wire EDM.
