SURFACE ROUGHNESS ASSESSMENT BASED ON DISCRETE MODEL REPRESENTATION FOR ADDITIVE MANUFACTURED PARTS
Journal Title: Periódico Tchê Química - Year 2018, Vol 15, Issue 0
Abstract
With any method of manufacturing parts of their surface cannot be completely smooth, perfect. There are always more or less pronounced irregularities of various shapes and heights — traces of the casting mold, sizing rollers, cutting tools, etc. The height, shape and location of these irregularities depend on a number of factors and conditions related to the material properties, processing technology, cutting speed, quality of tools. The emergence of new developments in the field of materials science and their possibilities used in layer-bylayer additive manufacturing (AM) method promotes the development of innovative solutions that increase the efficiency of producing complex parts and improves the quality. This paper describes one of the method (hypothesis) for roughness assessment that can be calculated during preparation of the 3D printing process. The calculation of the roughness surface is based on the voxel 3D model generated from the polygonal model (STL).
