A high level of glossiness on a floor tile surfgace is very much appreciated by customers, in spite of the masive costs the polishing generates. In the case of porcelain stoneware tiles, poliishing often accounts for 30% of the final costs. Nevertheless, this cost can be reduced by optimizing either the scratching phenomena or the polishing kinematics, which is the subject of the present work. Kinematics optimization deals with all the available motion of the polishing machine, with it turn governs the abrasive path over the tile surface. This path can be analytically determined so that a model can be elaborated to predict the trajectory of the abrasive particles at every instant. the goal of thes work is to understad the glossiness distribution over the tile surface as a function of the polishing kinematics. An industrial polishing line was computationally modelled using common indsutry parameters as input variables. The polishing enhancement could be presented, in rel time, by intensity colour graphics corresponds to a small proportion of the real tile surface. In order to check the model adequacy the values predicted were then compared with those attained in the literature, as well as with some real glossiness values measured in an industrial polishing line. Good agreement with the literature was achieved, so the software developed can be really used as a guideline for furthers studies on gloss enhancement in ceramic tile industries
