STUDY OF MECHANICS MOTION ON THE SURFACE ROUGHNESS OF SS304 APPLIED FOR SHAFT CONVEYOR

Abstract

The shape and surface roughness of a product produced by a machine, such as a lathe for example, plays an important role. In this case caused by the roughness and shape of the product related to wear, friction, lubrication system and others. In the machining process will determine surface roughness at different levels where the surface roughness can be used as an evaluation of machining products. Surface roughness on a product does not have to have a large or small value, roughness of a product requires different values according to its function. One product that requires a low roughness value is the shaft. In the analysis of surface roughness, the step taken is to choose the type of workpiece material. For the selection of material in the analysis of roughness this time the material used is SS304 and SS316. The next process is the process of making workpieces with a manual lathe with variations in rotational speed, feeding speed and depth of cut that has been determined on each workpiece. In collecting surface roughness data on each workpiece that has been determined, the surface roughness value obtained in the smallest workpiece material is 2,419 μm at a rotational speed of 1000 rpm by feeding 0.10 mm/r and the value of surface roughness on the workpiece material the largest is 8.425 μm at a rotational speed of 1000 rpm with feeding 0.15 mm/r.
