INFLUENCE OF MACHINED SURFACE SHAPE ON LIGHT ABSORPTION

Abstract

There are different factors that have influence on light absorption of a given material, e.g. material colour and thickness, angle of light incidence, surface shape, roughness, porosity and surface cleanliness. This paper is focused on material ability to absorb light. For this reason, different surface shapes of a polyvinylchloride material were produced on CNC milling machine. There were investigated the effect of width, depth and number of differently shaped grooves on light absorption in this paper. It was found in this study that the effect of the surface shape has a significant influence on light absorption. This fact was verified by a computer simulation, which was performed using Wdls 4.1 software.
