Abstract
Experiments were carried out on different fiber-reinforced polymeric composites
in order to gain a deeper understanding of the significance and effect of each of
the physical and mechanical properties of the various composites on the quality
of the machined surface during cylindrical grinding. For such a comparison to be
valid the process parameters such as feed rate, depth of cut, and R.P.M. were
kept constant in each case. The results enabled understanding of the phenomena
of heat generation and heat dissipation during the grinding process. They would
also serve as an aid in selecting the appropriate type of composite for a specific
application.
Keywords: fiber-reinforced polymeric composites, grinding, properties of
composites.
1 Introduction
While fiber-reinforced polymeric composites are currently very popular in
fabricating boats, skiing gear, automobile panels, small rockets, and aircrafts,
their use as structural machine components has been quite limited. This is mainly
due to the difficulties encountered in achieving adequate levels of dimensional
accuracy and surface finish when those composites are subjected to precision
machining operations, e.g., grinding. Problems such as degradation, thermal
damage of the ground surface, excessive noise and vibrations, and clogging of
the grinding wheel are frequently encountered. This is evidently caused by the
nature and the physical and mechanical properties of this class of material, which
are different from those of metals.
Keywords
fiber-reinforced polymeric composites, grinding, properties of
composites.
