Optimization of the Cutting Process of Wood-Based Agglomerated Materials by Abrasive Water-Jet

Open access

Abstract

This paper deals with the cutting MDF, OSB, and plywood boards by abrasive water-jet (GMA Garnet Australian, grain size 80, MESH = 0.188 mm), with a kerf width depending on the material properties and technical parameters (material thickness, cutting direction, abrasive flow, and feed speed). The entry of water-jet cutting in the longitudinal direction produces changes in the material due to lateral leads spreading the width of the cut joints by an average of 0.20 mm for MDF boards, 0.3 mm for OSB boards, and 0.17 mm for plywood. On the exit side of the material, the water has the opposite effect. In relation to the thicknesses of the material, the width of the cut joints increases. The experiment has shown that the optimum value of the feed speed is explicitly 400 mm.min-1, at which the kerf width reaches the lowest dimensions both at entry and exit, and the abrasive flow of 450 g.min-1 has been shown as optimum.
