Abstract: The invention concerns a procedure for simulating a desired tablet pressing situation, the tablet compound being placed in a pressing matrix in the device and the compound being compressed with the aid of punch members provided in the device on opposite sides of the matrix, in accordance with a preselected motion path, in the procedure being measured forces acting on at least one punch member of the tablet press during pressing and/or the motion path of the punch member; the results of measurment thus obtained being transferred to a computer controlling the operation of the trial tablet press, and a file being formed thereof; during such simulation the motion path of the punch members in the trial tablet press being controlled in accordance with the file formed of the results of measurement.
