Abstract
The present invention has an object of simply and accurately measuring a load applied to a mechanical press. A test billet obtained from material of which the mechanical strength is uniform and which is finished precisely is placed on the press and pressed between a slide and a bed of a press, whereby an upsetting amount and a pressure at that time of pressing the billet are measured by a load cell. As a result, a press load, which may be calculated by establishing as functions such elements as material, deformation amount, and working speed of a test billet, can be accurately obtained by a simple measurement of the test billet to which established properties have preliminarily been given.
