INFLUENCE OF MACHINING PARAMETERS ON THE SURFACE ROUGHNESS OF POLYMERS

Abstract

CNC technologies are one of the most common technologies in all branches of industry, and milling is one of the most common machining processes in the industry. In addition to all types of materials that are available in various industries, polymers are certainly one of the most represented. Good quality of treated surfaces is certainly one of the primary goals of material processing. Manufacturing technologies such as injection molding and 3D printing cannot always deliver good surface quality, and for this reason it is necessary to additionally machining parts and materials. In addition, different parameters during machining, such as cutting speed, depth of cut, feed can have a great influence on the surface roughness and machining quality. In this paper, the effects of machining parameters for several types of polymers will be presented from the aspect of surface roughness
