Application of an assistant teaching system based on mobile augmented reality (AR) for course design of mechanical manufacturing process

摘要

This assistant teaching system is based on advanced mobile AR technology applied in the practical teaching of course design of mechanical manufacturing. The assistant teaching system implements the function of superimposing the digital information over the real world, rotating and zooming the 3D model, showing the cross-sectional model and so on. In combination with the actual teaching requirements of course design of mechanical manufacturing, the function of arranging the process routes of the typical parts in course design of mechanical manufacturing process is designed. The assistant teaching system assists teachers to carry out some teaching work to alleviate the teaching burden of teachers. The practical application shows that the innovative mobile augmented reality teaching promotes students to understand the teaching content flexibly and enhance the quality of manufacturing technology course design. At the end of the paper, the typical part “CA6140 lathe fork” is used as an example to introduce the function and operation of the system.
