ABSTRACT:
Method and apparatus applicable to a press using a die set including a lower and an upper die which are removably installed movably towards and away from each other to perform a pressing operation under the adjusted operating conditions. A memory is provided to store machine information relating to the press and necessary to determine optimum values for the operating conditions. Die set information relating to the die set and necessary to determine the optimum values are received through a data input device. A calculating device calculates the optimum values, based on the machine information and the die set information, and an adjusting device automatically adjusts the operating conditions according to the calculated optimum values.
