Experimental Investigation and Finite Element Analysis of Boring Tool vibration by using passive damper

Abstract

Boring is a commonly used operation to enlarge the existing holes of machine structures. When boring tool
is slender and long, it is subjected to excessive static deflections or a self-excited chatter vibration which reduces the
accuracy and surface finish of the hole. It also causes accelerated wear and chipping of the tool. Internal turning
frequently requires a long and slender boring tool in order to machine inside a cavity, and the vibrations generally
become highly correlated with one of the fundamental bending modes of the boring tool. use of passive Damper of
different orientation reduces vibration level in Boring tool & tool holder &work piece to be enlarging hole improving
surface finish. Furthermore, the interface between the boring tool and the clamping house has a significant influence on
the dynamic properties of the clamped boring tool. This report focuses on the behavior of a boring tool that arises under
different overhang lengths which are commonly used in the manufacturing industry.
