Mathematical modelling of the surface roughness in orthogonal cutting of the massive wood

Abstract

ABSTRACT This paper presented the quality of the treated surface, which is most often followed by roughness representing micro-geometric irregularities of the treated surface. The processing influence parameters behaviour of on the roughness of the treated wood surface was considered, where the results of measurements of the average deviation of the roughness profile of the surface of beech and maple wood from the area of Bosnia and Herzegovina after processing with orthogonal cutting on a four-sided shaper was studied, at different feed speed and cutting depth . The mathematical model of the influence parameters on the treated surface roughness of solid wood was also presented. The paper presented a sample example of how a process can be predicted before it goes into production, avoiding exploitation testing and increased costs of the process itself.
