Servo positioning control method of forming machine control system

The invention relates to a servo positioning control method of a forming machine control system, which is characterized in that the actual torque of a servo motor is judged in real time in the process of executing a positioning instruction by the servo motor, and when the actual torque exceeds a set torque threshold value, the operation of the whole forming machine cannot be stopped immediately, so that the working efficiency is improved. However, the duration of the actual moment exceeding the moment threshold value is calculated, a moment buffer period is formed, and time can be provided for operation of a positioning instruction or other parts to continue to be executed; when the actual torque exceeds the limited time specified by the torque threshold value, the current positioning instruction is reset, a forced stop instruction is sent to the servo controller, the servo motor is forced to stop action, alarm information is sent out, an interruption request is not directly sent out once the torque threshold
