The processing status of automobile gear panel was analyzed. The traditional automobile gear panel is mainly made of plastic with complicated processing, cumbersome operation and low degree of automation. New wood composite board was used to process the gear panel.The characteristics of the gear panel, the layout of the size and the processing technology were analyzed and the processing technology of the automobile gear panel was determined. On this basis, the overall layout design of the special machine tool for CNC curve milling of automobile gear panel was carried out. The design scheme of main motion system, feed motion system and host part was determined. Based on the design principle and theory of the machine tool, the main body parts such as the guide mechanism, the frame mechanism, the follower pressure roller and the electronic control system were designed. The main force support frame of the machine tool was analyzed and the maximum stress and displacement range of the frame were solved by using SolidWorks software.The conclusion is that the rigidity, strength and stability of the frame meet the design requirements.
