PRELIMINARY IDENTIFICATION OF THE FEED SPEED INFLUENCE ON CHOSEN EFFECTS OF LAMINATED PARTICLEBOARD DRILLING

The aim of the investigations was to determine the influence of the feed speed during drilling on the multi-spindle drilling machine on the affluence height of the machined laminated particleboards. It was noticed that the affluence height got lower with the feed speed increase up to about 0.4 m/min, above this value the affluence height was stable till the speed reached about 2 m/min and above this feed speed value the affluence height became higher. The results of the investigation show that the optimal feed speed, i.e. the speed allowing to achieve the best quality of drilling of particleboards covered with chosen edge bands, is the feed speed in the range of 0.4–2 m/min.
