Abstract: In the teaching of undergraduate mechanical-manufacturing-technology-related courses, considering the danger environment and the process complexity of the large equipment manufacturing, it is quite difficult for students to carry out physical experiments in the physical laboratory or physical intelligent manufacturing workshop, which greatly limits the improvement of students’ engineering practice ability. On this basis, a virtual production workshop as well as the virtual simulation experiment teaching method for the courses group of mechanical manufacturing is proposed in this paper. Through the WebGL technology standard, the interactive operation of the turbine engine impeller automatic processing virtual workshop is established, and furthermore the virtual and real integration interface corresponding to experimental equipment such as the physical CNC machine tool, manipulator, AGV transportation cart and so on. Besides, the experimental function of mechanical manufacturing and control are developed, and the virtual simulation experiment teaching software is developed for the theoretical and practical teaching of mechanical courses. The relevant results have been applied to the teaching of many mechanical manufacturing courses, the students’ professional knowledge level and engineering application ability have been significantly improved, and the teaching effect is good, which proves the rationality and practicability of the practical teaching measure.
