A study on surface roughness of wood using CNC milling process

Abstract

The important aspect in machining process is the quality of milled product surface. Therefore, the choice of current cutting parameter is very important in order to obtain the desired surface finish. Thus, measuring and characterizing surface properties represents one of the most important aspects in manufacturing processes. The cutting experiments will be carrying using CNC milling, Spinner (Brand), VC810 (model). The factors that have been chosen in this milling operation including cutting speed [rev/min], feed rate [mm/tooth], depth of cut [mm] and tool diameter [mm]. The material used in this milling process is wood. A total of 9 experimental runs will be conducted using Taguchi approach Design of Experiments to identify the combination of parameter producing the smaller surface roughness value identify the combination of control factor levels for optimum surface roughness. From the analysis combination of parameter producing the smaller surface roughness value identified. Confirmation run with that combination parameter with are cutting speed = 6000 rpm, tool diameter = 16 mm, feed rate = 0.1 mm/tooth and depth of cut = 6.0 mm. As a conclusion, this research to obtain the best combination of parameter to optimize the surface roughness of wood.
