MCS-51 single microcomputers have been used widely in NC, especially in ecomical NC equipments in china. Based on MCS-51 single microcomputers, the NC lathe training equipment is designed with less money for the professional NC courses. After analyzing the feature of NC lathe and defining the functions of training equipment, Make sure to ordinary machine tools into economic numerical control machine tools，Ordinary lathe (C616) numerical control transformation design contents include: overall scheme determined and validation of the mechanical design and calculation of the transformation part (including longitudinal horizontal feeding system design and calculation) automatic transmission principle and main movement after reforming machine drive system of the machine speed motor design diagram control circuit design of design and calculation of the electromagnetic clutch In this graduation design, I acquainted with the machine electricity integral whole to turn the basic process of design, and integrate the knowledge that each one
