This paper focuses on the prioritization of factors having substantial effects on the surface roughness of wood and wood-based materials in the sawing process. Within the model, four main factors were defined: cutting tool properties, machining parameters, wood structure and properties, and cutting phenomena. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2018) 42: 364-371 © TÜBİTAK doi: Employing an analytic hierarchy process to prioritize factors influencing surface roughness of wood and wood-based materials in the sawing process Hilal SİNGER* , Şükrü ÖZŞAHİN Department of Industrial Engineering, Faculty of Engineering, Karadeniz Technical University, Trabzon, Turkey Received: Accepted/Published Online: Final Version: Abstract: This paper focuses on the prioritization of factors having substantial effects on the surface roughness of wood and wood-based materials in the sawing process. Within the model, four main factors were defined: cutting tool properties, machining parameters, wood structure and properties, and cutting phenomena. Furthermore, each main factor was subdivided into various subfactors. The analytic hierarchy process method was proposed to obtain the priorities of the factors. The results showed that feed speed, tooth shape and geometry, and cutting speed are the most important factors. Based on the obtained results, it can be said that the most important factors can be easily determined by the proposed method. Consequently, this study presents a road map for the wood industry to achieve a high quality surface. Key words: Analytic hierarchy process, multicriteria decision-making, sawing process, surface roughness 1. Introduction Wood materials have been widely used for interior and exterior decoration applications owing to their natural beauty and easy processing (Aydin and Colakoglu, 2005). After solid wood undergoes machining by sawing, planing, sanding, etc., it becomes a final product (Sofuoğlu and Kurtoğlu, 2015). The surface quality of wood subjected to machining is influenced by many factors related to both machining conditions and wood characteristics. The most important factors related to the machining .
