| Summary: | Compliant tools such as abrasive coated cloth, paper, and abrasive flap wheels
are commonly used in manufacturing finishing processes, especially in the aerospace
and precision engineering industry. Although such tools have been in use for a long
time for polishing, the mechanical behavior and material removal mechanisms of many
of these tools have not been understood and documented fully, as it has been done for
conventional grinding. The objective of the project is to determine material properties
of the abrasive flap material that affect its bending behavior and also to design and
simulate the flap 's bending behavior under static loading conditions using a finite
element software. The material properties determined through the experiments were
validated by the finite element models simulating real life behavior of the flap material
during one such experiments. There is a huge variety of abrasive flap materials
available and their material properties and mechanical behavior is largely
undocumented or proprietary. The experiments were conducted on an abrasive cloth
material used in one of the commercially available abrasive flap wheel models from
Ban Chu Leong Technologies Pte Ltd. The general limitations of this research work
are, the conclusions drawn from this research work directly pertain only to the
particular type of abrasive clothing under analysis. Moreover the analysis is limited to
modelling static loading behavior of a single flap and does not take in to account
dynamic effects. Further research work along the same lines may lead to improved
models that can be used to predict the compliant behavior of similar materials.
