Abstract: The LEBUS double-broken-line-groove winding systems are widely used in large tonnage winch drums which are safe and secure and can prolong the service life of the steel rope.In order to solve the batch processing problems of LEBUS grooves,a practical numerical control system for processing LEBUS grooves was designed in the paper which can be matched with the NC transformation of the old universal lathes.The design process of the numerical control system of the engine lathe for processing LEBUS grooves was discussed in detail,including the selection of the CPU chip,the expanding design of the memory,the expanding design of I/O interface,the expanding design of the keyboard and LED displaying interface and the expanding design of D/A interface.And the design idea of LEBUS grooves processing software was also given.The system has high control precision,simple structure,convenient operation,high ratio of performance to price and has certain popularization and application value.
