Additional edge preparation (ABP) is used to create Y or K cuts in thicker plates. Usually, a Y-shaped cut is made first, then a right-angle cut, and then a bevel cut, but it will still cut through the entire thickness of the material (increased by the angle). This cutting method is limited by the maximum thickness of the plate that the plasma source can cut. For example, a plasma source with a maximum cutting capacity of 50 mm can cut plates up to about 35 mm thick when cutting a 45° bevel. First cut the part into a right angle, then move to another part of the worktable, and then cut the upper bevel part of it, the situation is different. The machine will be able to cut bevels (for Y and K cutting) across the full range of plasma source capabilities.
This process is used with a special dedicated scanner (ABP scanner) that can identify the position of the cut part and its upper edge, and align it with the part’s cutting program. It can be used with spinners or 3D tilt head tool stations on DRM, MG and CombiCut machines.
