Abstract
The main objective of this work is to develop a mathematical model to evaluate optimum sanding conditions of Europen black pine (Pinus nigra). Samples were sanded using different of grit size, feed rate, cutting speed and depth of cut. Average surface roughness (Ra) values of each type of specimens were measured employing a stylus type of equipment. Interaction between sanding parameters and surface roughness of the species were analyzed using Minitab software and response surface methodology. Based on the fi ndings in the work feed rate, cutting speed, grit size and depth of cut values of 5,39 m/min, 19,75 m/sec, 220 (grit size) and 9 mm were determined as optimum sanding conditions.
Highlights
Sanding is one of the most common processes in the woodworking industry
The results showed the grit size, tooling resilience and grain orientation to be significant for all species
European black pine (Pinus nigra Arnold) species are extensively used in the furniture industry and they were selected for the study
Summary
Sanding is one of the most common processes in the woodworking industry. This process effects surface roughness and surface coating performance (Gurau et al 2015, Hiziroglu et al 2014, Kılıç et al 2006, Magoss 2015, Vitosyte et al 2012). The surface roughness is significant factor influencing overall manufacturing process such as bonding quality, painting properties and processing time. Wide belt sanding machine is commonly used for furniture industry. The machine conditions including grit size, feed rate and pressure effected the surface quality (Ozdemir and Hiziroglu 2007, Moura and Hernandez 2006, Gurau et al 2013)
