Abstract
Press working is the probably the earliest occupation known to mankind.
Native metals have been formed technological and shaped 7000 years
ago. Press working industry utilize million on man, production tool,
forming processes, building and other related facilities, in order to
form and produce the material to meet the increased demand of mankind.
The high productivity of forming process, the simplicity of press operation,
all leads to greater extension of this method manufacturing.
Of course, the many alternative processes require the complementary
tooling, while in the metal forming dies or press tools the trouble has
often been traced to an adequate grasp of the basis of design construction.
Press tools and metal forming processes in which they are used in
an inadequate grasp on the basis of design and construction are greatly
improved of lathe both in design and in regards to capacity.
Press working may be defined as the chip less mfg. process by
which various components are made from sheet metal. These process
is also termed as cold stamping. The machine used for press working
is called press. The sheet metal operation done on press be grouped
into two categories : i ) Cutting Operation and ii ) Forming Operation.
In cutting operation, the w/p is stressed beyond it’s ultimate
strength. The stresses caused in metal by the applied force will be
shearing stress. In forming operation, the stresses are below the ultimate
strength of the metal. In this operation, there is no cutting of
the metal but only the contour of the w/p is changed to get the desired
product.
