In order to reach a high machining accuracy, improve production efficiency, the general press numerical control open loop transformation. The transformation is mainly from the mechanical part and control part . The first is the original ordinary punch worktable engineered to contain two directions of the working table, the control system uses the computer to open-loop control on the vertical and horizontal system,the drive element adopts a step motor, drive system adopts a ball screw. The control part uses the MCS-51 series singlechip motor control system, so that the punch automatic feeding, automatic stamping and other functions. In order to coordinate the relationship between the mechanical part and control part, Position sensor needs to be installed in the press punch, to detect punch location, so that the control section to issue appropriate instructions to control the punch to make the appropriate action. The mechanical part of the ball screw and the selection of step motor and related calculati
