There are many ways to achieve knowledge. The experience presented in this paper is one that describes the knowledge achievement process thru knowledge models - in this case using concept maps. The subject of the experiment was to design a knowledge model on a technical subject: turning. The project participants were the students of the terminal year from the Engineering Faculty of Sibiu, Lucian Blaga University. Especially the technical field is one in which knowledge (information interpreted with a result) are hard to reach because of the important quantity of information which in the absence of the right connections made between them they remain raw dates, difficult to understand, hard to integrate in a real technical context in order to solve a given problem.
