Always in the Production process there is a long felt need
to improve the quality of product, minimize rejection and
increase the productivity per person, to cater to the pressing
circumstances in the GLOBALISED WORLD ECONOMY.
The answer to this need is use of Special Purpose Machines
giving very high productivity. The theme can be further
elaborated by doing a full scale Automation of the of
the industrial process, wherever possible. The use of special
purpose machines & automation minimizes possibility of
human errors and also reduces human fatigue in carrying out
repetitive operations again & again. It also assures the
quality and interchangeability of parts, by carrying out the
same designed process each time without any shortcuts.
The special purpose
machines & automatic machines are designed to operate
continuously for 24 hours a day, with minimum supervision. The
special purpose machines are generally product specific &
they are required to be designed & developed for each
specific requirement. Sometimes it may be possible to cater to
the jobs having similar features but differing in dimensions
by using change tooling concept.
These machines are
either cam operated machine or they use Hydraulics &
pneumatics as actuating elements or combination of all the
three of them. Many times a dedicated programmable logic
controller is used in conjunction with positional sensors
& transducers, to give commands to the actuating elements
some times different special motors like stepper motor &
servo motors are used as actuating element. The productivity
achieved after all these efforts is very high. Productivity of
3 to 10 times are achievable. However to fetch the fruits of
these highly specialized machines the pre condition is that
the input to the automatic machine must have strict quality
control.
Special purpose machines & Industrial automation is in
great demand in this era of high competition amongst the
manufacturers of consumer products like Automobiles, Consumer
Durables Home appliances & White Goods etc.
