Abstract

The manufacturing industry is one of the largest industries in the world today, manufacturing industry is the largest industry in Indonesia and hold a great impact to the economic. In manufacturing industry, metal working is the largest sector, therefore optimizing the process in this sector will give a good impact to the economic. Optimizing process can be done on lathe, because lathe is the most widely used machines in this sector, almost all the factory is using this kind of machine.
Optimizing the lathe process is to maximize the cutting speed, feed rate, and depth of cut by increasing the spindle speed. high speed of spindle can make a vibration on the workpiece which lead to chatter and risk of critical shaft that will result to high vibration amplitude. This can be overcome by using Dynamic Vibration Absorber (DVA).
In this final project, we will design and make the Radial Vibration Absorber (RVD) system, which consists of a disk which is a holder for 4 DVAs, is placed on a long slim shaft. RVD is designed to be able to reduce vibration at the working frequency of the lathe. testing is carried out in two stages, first is where the conditions of the main system with and without using RVD. The second condition is carried out by vary the placement of RVD in areas that have been determined on a long slim shaft.
The results of this final project are Radial Vibration Damper for shaft with length of 1m and diameter of 10 mm has been made, and can reduce vibration at the working frequency of 320 rpm - 900 rpm. It was found that the greater the system rotational speed, the higher the response acceleration vibration obtained. The variation in RVD position on the shaft affects the response dynamic shaft, where maximum reduction is at point 4 and 5 with value in the X axis direction of 74.83% at rpm 320, on the Y axis 57.33%, at rpm 540 on the X axis at 1.66%, Y axis (point 5) 37.17%, at 900 rpm on the X axis at 67.51%, on the Y axis (point 5) at 61.47%.
