Static analysis of composite boring bar using FEA

Abstract

Boring is an internal turning operation in which pre-drilled holes or holes in a cast, etc. are enlarged. The relative motion between the workpiece and tool in cutting direction results deflection in the boring bar and deformation in cutting insert during the boring operation, which produces the poor surface finish. In view of this a static analysis of the composite boring bar has performed and compared with conventional one. Moreover, the modal analysis of conventional and composite boring bars has shown for six modes of vibrations to find out the natural frequencies using ANSYS® 15.0. It has been observed that there are four bending and two torsion modes available in the six modes of vibration. Further, the total deformation, equivalent stress and equivalent strains have been taken from the simulation and compared with the composite and conventional boring bars.
