Press-working apparatus and related method

Abstract

Press-working apparatus, monitoring device, and method of operating a press-working apparatus with a press-working monitoring device and one or more displacement sensors including a first displacement sensor comprising a first primary attachment part mounted on a first part of the press-working apparatus, a first secondary attachment part mounted on a second part of the press-working apparatus, and a first sensing part, the first sensing part being arranged between the first primary attachment part and the first secondary attachment part, wherein the first displacement sensor is configured to provide a first output signal indicative of deformation of the first sensing part is disclosed. The method comprises: obtaining the first output signal from the first displacement sensor while moving the first part and the second part along a main axis in relation to each other, thereby deforming the first displacement sensor; determining if an error criterion based on the first output signal from the first displacement sensor has been met; and providing a control signal indicative of an error to the press-working apparatus if the error criterion is met.
