In the turning operation, chatter or vibration is a frequent problem, which affects the surface finish and tool life. In all cutting operations like turning, boring and milling vibrations are induced due to the deformation of the workpiece, this implies economical disadvantage. The main objective of the proposed work is to design damped tool holder for existing machine tools with low cost fabrication techniques. In this investigation, improvement of the damping capability of boring tool and suppression of chatter vibration using lead damper and Impact damper are analyzed. The lead damper Inertia mass of the boring tool has been Increased to suppress the chatter vibration. In impact damper kinetic energy of free mass is dissipated. Finite element analysis is performed to study dynamic behavior of composite tool holder, the effects of overhang length of boring tool with lead damper, and the effects of impact damper in boring tool was investigated.

Abstract


In the turning operation, chatter or vibration is a frequent problem, which affects the surface finish and tool life. In all cutting operations like turning, boring and milling vibrations are induced due to the deformation of the workpiece, this implies economical disadvantage. The main objective of the proposed work is to design damped tool holder for existing machine tools with low cost fabrication techniques. In this investigation, improvement of the damping capability of boring tool and suppression of chatter vibration using lead damper and Impact damper are analyzed. The lead damper Inertia mass of the boring tool has been Increased to suppress the chatter vibration. In impact damper kinetic energy of free mass is dissipated. Finite element analysis is performed to study dynamic behavior of composite tool holder, the effects of overhang length of boring tool with lead damper, and the effects of impact damper in boring tool was investigated.
