Abstract: As an indispensable technical equipment in the machining industry, it is important to train the technicians skilled in CNC machine tools. However, the training of CNC machine tool technicians requires expensive equipment and a large area of space, which needs a lot of funds. This paper establishes a three-dimensional model of CY-K360n machine tool, and completes a machine tool processing system based on Unity3D animation effects and UI interactive control. Export the machine tool machining system to the front desk in WebGL format and display it to users in B/S mode by ASP.NET technology, Implement functions of machine tool machining mode introduction and interactive machine tool demonstration. By using this machine tool processing system with browser, the difficult problems such as expensive learning price of machine tool processing had been solved, and the defect that corresponding software must be downloaded when using machine virtual system is compensated at the same time. It provides a new mode for operation and training of virtual machine tools.
