In view of the requirements of the preimmersed cloth belt winding molding process,a new type of CNC tape winding machine was designed on the basis of the traditional horizontal CNC lathe.According to the requirements of the winding process,the mechanical structure of the CNC cloth belt winding machine was studied,the drive control system was designed based on the Huazhong 8-type numerical control system;the workshop field interactive control system was developed combined with Mitsubishi PLC and touch screen;the upperposition machine collection and monitoring system was constructed,and the upload and download of G code files between the upper computer and the CNC system was realized by FTP protocol;realtime acquisition of PLC status data was realized by using Modbus protocol.Through the running test,it is verified that the system has high processing efficiency,good expansion performance and high engineering application value.
