ACKNOWLEDGEMENT
We are feeling pleasure introducing our project “MANUAL SHEET METAL
PUNCHING DIE” result of our new radical ideas to significant windup our studies during in
course “DEGREE IN MECHANICAL ENGG.” at JAMIA INSTITUTE OF ENGINEERING
AND MANAGEMENT STUDIES, AKKALKUWA. Suggestion to improve quality of product
are always welcome. Many hands have given their active support & contributed for design &
development of “MANUAL SHEET METAL PUNCHING DIE” We would like to thank our
guide PROF. IQBQL MANSURI. We would also like to thank our respected principal of
JIEMS PROF. SAYYAD IRFAN & our head of the department of Mechanical Engineering

Abstract
This paper describes an integrated system for the design and production of sheet metal
parts of “Manual Sheet Metal Punching Die”. We have identified some important features for
the sheet metal bending process. These features are automatically generated as the design
progresses. After the designs are complete, our automatic process planning system uses the
features and generates new ones to aid the production of plans with near-minimum
manufacturing costs. Finally, these plans are used to produce parts on an automatic bending
system.
Once a plan is generated, it can be used to manufacture the part, and to provide feedback
to design and other factory systems. The application of features and the potential feature
interaction problems are discussed. Several key manufacturing problems are also considered and
the result of planning is used to resolve these problems. By solving these feature interaction
problems and often practical manufacturing issues, we are able to plan and manufacture the
majority of the parts we have tested under one hour after the flat patterns are prepared.
The development of our design started with evaluating the current process Tri State used
for cutting the screens. Apparent problems included extremely low production, poorly cut
circles, sharp edges and the use of scissors without protection. Some of the cut circles failed the
only quality check, which is the insertion of the screen circle into a cap to ensure a snug fit.
The final prototype design cuts 0.2- 6 mm circles per cycle while reducing material
handling. The device tackles a variety of technical challenges to improve the quality and
production rate of the screen circles.
We believe that the design will open this task up to lower functioning workers because it
is a simple, two step operation that requires only the use of scissors which they are already
proficient with. This is a significant improvement over the multi-step hand cuts that workers
were previously performing.
