PURPOSE:To perform the setting based on a sure estimation extremely in short time and automatically by setting the set value of a setter based on the calculated reference value and by controlling the filling powder quantity, etc. by comparing the electrical signal by the forming thereafter with each set value. CONSTITUTION:The standard deviation is calculated by an arithmetic processing unit 9 by processing with an operation the maximum value of the waveheight value of the forming pressure subjected to a sampling and based on this standard deviation, the reference value of the setter is operated. The respective set value which is the control level of the setter 10-15 at each step is decided by operating it based on this reference value. The arithmetic processing unit 9 and setters 10-15 at each step are connected as SET 1-6 respectively and the decided set value is automatically inputted into the setter 10-15 of each step. The arithmetic processing unit 9 performs the sampling in order while under the forming compression on each given time, on each given number of formings or the optional signal of the external part, etc. and resets the set value automatically by calculating the standard deviation of a new state. |
