INFLUENCE OF TECHNOLOGICAL FACTORS UPON OF THE ROUGHNESS OF THE EXTERNAL CYLINDRICAL SURFACES PROCESSED WITH VIBRATORS ABRASIVE BELT

Abstract

Finishing and superfinishing active surfaces of workpiece are expensive operation which requires a judicious choice of working parameters. This paper presents the results of research conducted on vibro finishing external cylindrical surfaces using the abrasive belt. The processing was performed using a vibro-smoothing device mounted on a lathe. It was analyzed the influence of the abrasive belt grain, normal force, the rotation speed of the workpiece and the work time for piece roughness. Based on a 24 factorial experiment it was obtained a matrix model which allowed the analysis of factors and their interaction influence on roughness. The results have shown that the most important factor is the belt grain, followed by working time and the speed of workpiece rotation.
