Abstract
A press load measuring apparatus includes: strain gauges attached to respective columns of a press machine and configured to detect strains generated in the respective columns respectively in association with a press load acting on a slide of the press machine, an inertial force calculator configured to calculate a slide inertial force proportional to a product of a mass of a slide and a member connected to the slide and a slide acceleration detected by an acceleration detector, and a press load calculator configured to calculate press partial load signals before calibration based on a strain signals detected by the strain gauges, eliminate a slide inertial force signals from the press partial load signals before the calibration, and calculate calibrated press partial load signals.
