Effect of CNC application parameters on wooden surface quality

Objective of this study is to determine the parameters such as spindle speed, feed rate and wood material on surface quality. Medium density fiberboard (MDF), Beech (Fagus orientalis L) and Ayous (Triplochiton scleroxylon) were selected for the study. Wood specimens were prepared using different values of spindle speed and feed rate. Surface roughness (R-a) values of specimens were measured by employing stylus type of equipment and laser based robotic measurement system. Laser based robotic measurements were obtained by Matlab software. The objective of the techniques were to (1) determine the significant parameters on wood surface quality (2) analyze the main and interaction effects in the CNC cutting process (3) compare the data from the robotic system with the stylus type of equipment. As the result of this study, spindle speed of 18,000 rpm and feed rate of 2 m/min resulted with minimum surface roughness values of MDF, Ayous and Beech wood for laser and stylus techniques.
