Abstract
When obtaining load displaying calibration data, first, a reference die height position (a) where a load (F) of a mechanical press (1) comes to minimum load value (Fa) is sought as well as a reference die height position (f) where the load (F) comes to maximum load value (Ff). Then a plurality of intermediate die height positions (b . . . e) are selected between these reference die height positions (a) and (f). Subsequently, a load is imposed on the mechanical press (1) at each of the die height positions (a . . . f) and a pressure sensor (33) senses peak oil pressures (Pa . . . Pf) corresponding to the respective die height positions (a . . . f). Thereafter, relative relationships between load values (Fa . . . Ff) corresponding to the die height positions (a . . . f) and the peak oil pressures (Pa . . . Pf) are obtained as a characteristic curve (B).
