Abstract

In this paper, a damper with a combination of neoprene rubber sheet and hydraulic shock absorber is developed to reduce the vibration in the milling operation. The target of this project focus on the design of the damper and the data obtained from the table dynamometer. The experiment includes cutting force measurement, amplitude measurement, and surface roughness measurement during the milling operation. As the main objective is to reduce the vibration in milling operation, neoprene rubber sheet as a proven material that can reduce the noise generate by the cutting tool and machine is attached on a side of the damper, to increase the surface interaction of the rubber sheet with the work piece. On the other hand, a hydraulic shock absorber is inserted into the damper to maximize its function to reduce the vibration from the cutting tool. With the function of slowing down and reducing the magnitude of vibratory motions by turning the kinetic energy of suspension movement into heat energy, the value graph of amplitude against frequency can be lower, which prove that the vibration is reduced.
