Böge 230 Below is a sketch of an example of a sheet metal part to be punched from a sheet or strip. During punching, the parts are sheared from the sheet along their outer edge. The shear force is distributed evenly over the entire circumference of the punched part. The resulting cutting force therefore acts at the centroid of the circumference (centroid of the line). To avoid bending forces on the punch of the die, the punch axis must pass through the centroid of the line of the cutting edge circumference. The location of the centroid of the circumference for the sketched sheet metal part is to be determined.
