Medium-density Fiberboard (MDF) and Edge-glued Panels (EGP) after Edge Milling - Surface Roughness after Machining with Different Parameters

Abstract

The mean arithmetic deviation of the roughness profile was investigated during cylindrical milling of the board edges. The machined materials were a medium-density fiberboard, medium-density fiberboard with single-sided lamination, and edge-glued spruce panel. Contactless and contact profilometers were used to measure the roughness. Both methods were evaluated and compared. Tungsten carbide blades with three different compositions and treatments were used. The effect of the cutting speed (20 m/s, 30 m/s, 40 m/s, and 60 m/s) and feed rate (4 m/min, 8 m/min, and 11 m/min) on the surface roughness was also monitored. The results of this study compared two different methods for determining the surface roughness. The measurements were more accurate with a contactless profilometer, but the price is higher than that of the contact method. The operation was also more complicated, and the measurement itself took longer with a contactless profilometer. The evaluation of individual surface quality variables was faster with a contact device. The best results in terms of the surface quality were achieved by lowering the feed rate and increasing the cutting speed.

“…There is no difference between feed rate groups of 3 and 5 m/min. Similar results were reported about the effects of feed rate on the surface roughness by some researchers (Davis 1962;Lou et al 1998;Deus et al 2015;Sedlecký 2017;Sedlecký et al 2018;Bal 2018). 4 shows Duncan test results about the effects of finish depth on the Ra values.…”

Construction of Wood-Based Lamella for Increased Load on Seating Furniture

“…With dependence on the type of chair construction, the joint between the side rail and back leg or the seat-back joint is the most stressed joint [86][87][88]. This fact was confirmed in the process of lamella chair construction with the stress concentrated especially in the mold of seat frame.…”

Investigation of the Effect of Machining Parameters on Surface Quality in Bamboo

“…More accurate results in measurements were obtained with a non-contact profilometer, but it was long lasting and higher in terms of cost. The best results in terms of surface quality were achieved by reducing feed rate and increasing cutting speed [24].
