Evaluation of CNC routed surface quality of maple (Acer pseudoplatanus) and oak (Quercus robur L.) with different milling angles as function of grain orientation

The study assessed CNC routing quality on maple and oak samples, using 90º V-Grooving router bits at various milling angles as function of grain orientation: 0°, 15°, 30°, 45°, 60°, 75°, 90°, feed speeds 3 6 m/min spindle speed 15,000 rpm. was evaluated by roughness parameters for the V flank surfaces visual examination flanks’ edges. change in had no significant effect flanks surface both species, but values were considerable higher samples u=3 (Rk = 23.7 µm compared to along grain, Rk=9.83 u=6 m/min) due possible processing vibrations. angle orientation case oak, increased with cutting from 0° (Rk=11 13 µm) 60°(Rk =28 30 µm). Fuzziness around earlywood pores speed. A substantial increase waviness coinciding annual growth areas measured crosscut (Wa 34.0 µm, Wa =7 .39 grain). not sensitive variation or 4 For edges, best option found wood worst 60º, which caused biggest ruptures especially speed, species.
