Abstract
Computer-aided design and manufacturing is related to usage of a wide variety of technologies for performance of engineering tasks like: analysis, planning, design, simulation, diagnostics, optimization, producing. The integration of CAD /CAM and AR system play an important role in achieving proper understanding of the 2D and 3D graphical objects modelling. This unity becomes a fundamental part of a standard design process.
The aim of the paper is to summarize and analyse existing innovative solutions in utilization of augmented reality in computer-aided engineering practice and received knowledge to be used in the courses from Higher education. Also, the exploration about augmented reality usage in teaching, learning and assessment in university courses is performed in order to be chosen technology solution for delivering the knowledge in the context of CAD/CAM systems.
The research method for review performing is based on examination of scientific papers indexed in SCOPUS and Web of Science, indexed by search engines Google Scholar, Google Search and Semantic Scholar. The keywords augmented reality, CAD, CAM, product design, product manufacturing, engineering, are used for forming several searching queries, investigating the topics concerning AR in CAD/CAM systems.
A conceptual meta-model outlining the utilization of augmented reality technology in CAD/CAM systems and application of this knowledge for engineering education is developed. It consists of two parts. The first part describes the AR technology usage in CAD/CAM engineering process that includes several stages in design and manufacturing of products. It can be said that many of the stages are supported by AR for documentation, presentation and experimentation. The second part explains the utilization of AR technology in engineering education. An AR-based eLearning system should possess features for teaching, learning and assessment through usage of AR web-based, mobile-based or combined technologies. The summarized knowledge about facilitation of activities in CAD/CAM process through AR will be used for educational purposes and delivered also with AR technology. |
