Abstract
In boring process, casted, forged, or extruded holes in components are finished with a boring bar having cutting insert at its frontend. Dynamic and static deflections are always there in the boring bar due to its slenderness. The generating force for chatter is supplied by the cutting process itself, so it creates problems in achieving desired productivity. The main goal of this research work is to amend the rendition of boring tool with the help of shim having good damping capacity, which is placed under the tool insert. Here, brass shim is used and experiments are performed with and without shim one by one on CNC machine. Whole experimental data of acceleration is collected using CoCo80 dynamic signal analyzer. Using this data, various plots like time response plot, frequency response plot, Poincare plot, orbit plot are obtained to check for motion behavior. Surface roughness is also measured using surface roughness tester. The proposed concept shows effective chatter suppression strategy in boring operation.
