Introduction

The Center for Testing and Calculation of Machine Elements and Machine Systems - CIPMES is located at the Faculty of Engineering in Kragujevac in room C-IV-3. The center gathers all interested teachers and associates of the Department of Mechanical Constructions and Mechanization, and if necessary, other teachers from the Faculty are hired, as well as industry experts. The activities of the Center are related to scientific - research work (preparation of doctoral dissertations and writing scientific papers), permanent education (organizing trainings and courses for unemployed engineers, as well as engineers employed in the field of product development), publishing, cooperation with business...

The section "Innovations of machine elements - NAME" was formed within the Center. The primary goal of the section is to prepare the students of the Faculty of Engineering for the competition in Mechanical Elements at the machine races (in the previous two machine races, our students won first place). Also, within the section, we organize additional work with interested students in the field of mechanical elements. We make models of machine elements and machine assemblies on the available equipment of CIPMES in order to facilitate mastering the material.
