Effect of Impact Mass on Tool Vibration and Cutting Performance During Turning of Hardened AISI4340 Steel
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2014, Vol 11, Issue 2
Abstract
A major apprehension in manufacturing industry is the tool vibration, which has considerable influence on productivity and production costs. The present investigation aims at developing impact mass for suppressing tool vibration and promoting better cutting performance during turning of hardened AISI4340 steel using hard metal insert with sculptured rake face. An impact mass used in this study consists of a concentrated mass made of brass of predetermined size and shape mounted on the shank of tool at a specific location. Impact mass was designed and the location of the damper on the tool shank for achieving effective damping was determined using computational analysis. When the damping mass was mounted on the tool shank, its vibration characteristics got altered and provided an inherent damping capability to the tool holder for suppressing tool vibration. Cutting experiments were conducted to study the influence of Impact mass on tool vibration and cutting performance during hard turning. From the results it was observed that the use of impact mass on tool shank reduces tool vibration and improves the cutting performance effectively.
