Abstract:
Single point incremental forming (SPIF) is more
accurate and economical than the conventional forming
process for customized products. Majority of the work in SPIF
has been carried out on metals. However, polymers are also
required to shape. Polycarbonate has wide application in safety
glass, bottles, automotive and aircraft industry due to its
transparent as well as attractive processing and mechanical
properties as compared to other polymeric plastics. In present
work, the Polycarbonate (PC) sheet of thickness 1.8 mm is
deformed to make a square cup at different angles. Tensile
testing is done to analyze the effect of wall angle on the
deformed cup. This work illustrates the effect of the SPIF
process on material strength in a different directions(vertical
and horizontal) of the final deformed product. Tool forces are
evaluated using ABAQUS® simulation for SPIF. Numerical
simulation approach is used to calculate the fracture energy,
which utilizes the force-displacement curve of the specimen and
is verified.
