Abstract

Detecting the bending angle (beta) between adjacent sides of a metal sheet consists of measuring the distances (D) between the sides of the sheet and the face of the die. via magnetic sensors (18,19,20) fitted into the faces of the die. These distances are used to calculate the angles (gamma1, gamma2) and by algebraically summing up these values together with the angles (alpha3,alpha4) in the die the deg. of further bending required can be ascertained.
