Title: Relationship Between Parameters of the FSP Process and Torque Acting on a Tool / Analiza zależności parametrów procesu tarciowego modyfikowania warstwy wierzchniej i momentu obrotowego narzędzia
Abstract: The effect of rotational and travelling speeds and down force on the torque in Friction Stir Processing (FSP) process is presented. The relationship between rotational speed and torque was modelled by an exponential function. The dependence of the travelling speed and down force affecting the torque was successfully approximated by linear functions. To find a dependence combining the spindle torque acting on the tool with the rotational speed, travelling speed and down force the artificial neural networks was applied. Studies have shown that the increase of rotational speed causes the decrease of torque while the increase in the travelling speed and down force causes the increase of the torque at the same time. Tests were conducted on casting aluminium alloy AlSi9Mg. Application of FSP process resulted in a decrease of the porosity in the modified material and refined microstructure.
