One ought to all the time reduce high precision machining elements within the boundary of the sheet dimension and not use the sheet edges as a border. During laser chopping a portion of the material is burnt away when the laser cuts by way of, leaving a small gap. This ‘gap’ identified as|is called|is named} the laser kerf and ranges from 0.08 – 0.45mm depending on the material sort, thickness and other conditional factors. A minimal distance of 1-2mm between elements must be left to avoid unintended crossover chopping. Bend reliefs will be no deeper than the material thickness plus the bend radius. Bend 2 reveals an oblong relief reduce into the part, the depth of the relief should be greater than the radius of the bend.
