Effect of thermal modification on properties and milling behaviour of African padauk (Pterocarpus soyauxii Taub.) wood
Original language description
The purpose of this study was to analyze the effect of thermal treatment on chemical changes, mechanical properties and machining behavior of African padauk wood. Thermal modification of padauk wood was carried out at 3 different temperatures (160 degrees C, 180 degrees, and 210 degrees). Effect of modification temperature on chemical constituents and bending proper-ties of padauk wood were ascertained. Thermally modified and un-modified samples were subjected to milling operation with combination of various processing parameters such as cutting speed (20, 30, 40 m/s), feed speed (4, 8, 11 m/min) and rake angle (15 degrees, 20 degrees, 25 degrees), to obtain the optimum combination in terms superior surface quality (surface roughness and surface waviness) and minimum energy consumption. Cellulose and lignin proportion increased while hemicellulose proportion reduced significantly following thermal modifi-cation. Modification temperature, particularly 210 degrees, had significant effect on the chemica
