Augmented Reality (AR) technology to support learning activities becomes a trend in education and effective teaching aids for engineering courses. This paper presents initial results of a project aimed to transform the current learning process of Computer Aided Manufacturing (CAM) by designing and implementing an interactive AR learning and simulation tool to help students to develop a comprehensive understanding of technological models and features in milling processes. We present a marker-based platform that uses AR as a medium for representation of prismatic milling processes to facilitate CAM education and it should enable a faster comprehension of complex spatial paths and overall machining system.
