Vibration problem during metal cutting is a degrading reality in the manufacturing industry and have a negative impact on the productivity which increases the over all production costs. Sometimes it’s also impossible to achieve the required tolerances. Different methods can be applied to reduce the vibrations, for example by using passively tuned damper or active control. This paper examines the dynamic properties of a boring bar with passive tuned damper, aiming on enhanced vibration con-trol combining passive control and active control. By combining these two methods it is likely that the performance of the passive tuned damper will be enhanced in the sense of wider working range with respect to cutting parameters and materials of workpieces. However, implementation of effi-cient and stable methods requires in-depth knowledge concerning the dynamic properties of the tooling system. The examination of the passive boring bar covers a wide range of cutting parame-ters and the main classes of workpiece materials. This is the first step in the development of a bor-ing bar involving two technologies complementing each other, that is, passive tuned damper and active control which is an already patented technology.
