This thesis shows the production process of the construction of lever casting models. It encompasses the description of technological model making process, as well as the practical production of the model in the production line. During the model making process CAD/CAM design and manufacturing equipment was used. 2D drawings were made in Autocad program, 3D models in Solidworks program, while the components treatment was done with the usage of advanced CAM tools (Siemens NX) using the CNC machine. In the beginning of the thesis the casting technology is briefly described. After the description, lever construction in AutoCad program is illustrated. Later, a 3D model was made using SolidWorks program. Following the technological elaboration of the production, comes the model production in the production line of PIB extra Ltd., Štefanec, whose main business activity is foundry pattern production.
