FABRICATION OF DUA RAM SHAPER TO REDUCING LEAD TIME AND
INCREASING MATERIAL REMOVAL RATE (MRR)
Synopsis
Mechanical engineering without production and
manufacturing is meaningless and inseparable. Production and
manufacturing process deals with conversion of raw materials
inputs to finished products as per required dimensions
specifications and efficiently using recent technology
Shaper is the oldest machine next of lathe, but now days the
usage of shaper will reduce due to development of milling
,broaching, hobbing and CNC machines, reason is lead time is
more compare to the other machineries and MRR also less. So in
order to avoid the lead time and increase MRR a dual ram shaper
is used
In normal shaper only one ram is employed here due to
decreasing the lead time the dual ram is used, one ram is in
forward stroke and another ram is in reverse strock, both ram are
operated by a single motor, so continues duty load is applied for
the motor

Advantages
1. It is used in the mass production area.
2. Machine lead time is minimized.
3. Tool changing and setting operation is very easy.
Disadvantage
1) Operation performed in heavy duty shapers only
2) Suitable for when job width is more
