The surface quality is an important aspect in many scientific disciplines including engineering, industrial production, architecture, information technology and many other fields. Providing a high-quality surface is the primary goal of any manufacturing industry, including the woodworking industry. Despite numerous studies in this field, the results of the work conducted provide specific data on the species of beech wood that grows in the territory of the Republic of Kosovo. This paper aim is to analyse the influence of technological parameters (include feed rate, depth of cut and sharpness and un sharpness tool) on the surface quality of Beech wood (Fagus Sylvatica L). Eighteen good quality samples were randomly selected for the study. The initial dimensions of the samples were 60*40*450 mm. The quality of the surface was examined according to the ISO 4287 standard for the “Ra” and “Rz” profile. The quality of the surface of the samples processed into sharp and blunt tools was analysed, alongside an examination of the processing parameters such as feed rate and engraving thickness. The data show that with the increase in feed rate quality of surface decrease for both cases sharpened and unsharpened tool. It effectively conveys that when using the same processing parameters, the surface treated with the sharpened blade shows higher quality compared to the surface treated with the unsharpened one. The research indicates that with an increase in the depth of cut, there is a degradation in surface quality for both sharpened and unsharpened blade. According to the study's findings, it is advisable, during the planning, to limit the cutting thickness to a maximum of 1.5 mm.
