This machine tool can be used in the aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment and other industries of the country. Have a decisive influence. This paper studies the principle prototype of five-axis linkage NC milling machine used in teaching. Firstly, this paper describes the development history of five-axis linkage CNC machine tool, analyzes the advantages and disadvantages of the design of five-axis linkage gantry milling machine with different layout, and gives the structure selection and layout scheme of the principle prototype of five-axis linkage CNC milling machine for teaching. The layout scheme includes the layout design of the machine tool equipment, the working range of the double turntable feed system, the origin of the coordinate axis, the milling force and the welding process characteristics. Secondly, the layout design of the principle prototype of five-axis linkage NC milling machine for teaching is studied, including the five-axis linkage feed mechanism and spindle mechanism. The parameters of the actuator are calculated and the equipment is selected. The 3D simulation model of the principle prototype of the five-axis linkage NC milling machine for teaching is built by using Creo three-dimensional design software. From the point of view of reliability, this paper analyzes whether the design parameters of the principle prototype of five-axis linkage NC milling machine used in teaching reach the expected working parameters. Then, according to the 3D model of the prototype, the design and research of assembly process include the selection and simulation assembly of the motor, coupling, encoder, bearing, lubrication, sealing equipment, etc. Simulate the problems and solutions in the actual assembly process. Finally, using the simulation module of Creo, the statics and kinematics simulation of the feed transmission system of the principle prototype of five-axis linkage NC milling machine for teaching is carried out. The performance of static and dynamic performance of the principle prototype of five-axis linkage NC milling machine for teaching is analyzed, and the correctness of the design is verified, which makes the principle prototype of five-axis linkage NC milling machine meet the expected machining accuracy requirements.
