Abstract: Given knowledge points of engineering courses are boring, scattered and not systematic, having integrated online course resources, virtual simulation resources and offline resources, this paper designs the “online resources + VR/AR simulation resources + offline resources” combined teaching reform. The “gold course” construction plan of mechanical manufacturing technology is put forward revolving around the course objectives, curriculum resource development, and the selection of curriculum content, a progressive-like virtual simulation system that is learning-oriented is designed, and some examples are demonstrated.
