Mechanics
An unfold is a 2D representation of a copper item viewed from above in the state prior to mechanical bending. Unfolds are placed on graphical pages. For each unfold, only one item is represented. In addition to the display of the outer form, the unfold contains information on the bending positions. For this purpose, bending lines and bending extents are displayed. Furthermore, the bending positions contain information on the bending angle and the direction of the bending. The unfold is, thus, the manufacturing basis for the bending machine that processes the copper item further. The manufacturing data of the machining of copper items access the information contained in the unfold and, thus, control the manufacturing on the NC machine.
