University of Split (UNIST) faced the task how to improve courses according to the new teaching standards aiming that students not only gain knowledge of the field, but also become selfdirected learners who develop problem-solving skills. University Department of Professional Studies uses the problem-based (PBL) learning techniques in the courses. In the problem-based learning courses, students work with colleagues to solve complex and authentic problems that help develop content knowledge as well as problem-solving, reasoning, communication, and self-assessment skills. PBL learning is extended to a few courses including Mechatronics. During the course Mechatronics students faced the construction of the milling and drilling CNC machine. CNC milling machines can be found in various industries such as automotive, military, medical and construction. This paper deals with the process of design, manufacturing, testing and use of three-axis CNC milling machine carried out by students. The mechanical and electrical subsystems were built and tested at UNIST laboratories. In this paper the CNC mill mechanical and electrical systems are outlined and basic subsystems are presented.
