ABP: A laser scanner that opens up new possibilities
To allow a MicroStep machine to implement the additional beveling function, the machine must be equipped with one of MicroStep’s bevel cutting heads and an additional laser scanner unit. The unit is attached to the bevel head. The process is applied as follows: first, a 2D drawing of the pre-cut part is imported into the AsperWin MicroStep CAM software®. The machine operator defines the bevels required in the easy-to-use AsperWin interface. The system generates an additional bevel cutting program. To find the exact position of the part on the cutting table, the machine will use the ABP scanner. During the scanning process, the actual contour of the part is compared to its ideal drawing shape and if small differences are detected (a real part is almost never completely accurate), the system will align the cutting program with the actual shape to achieve the most accurate cutting results, possible. Once the starting point is verified, the cutting process begins. The system can make bevel cuts in V, Y, X and K (so for K and X cuts the part must be rotated and scanned again after the first phase of the cut is completed). Obviously, the technology allows scanning and processing parts manufactured with completely different technologies; for example, thick parts cut with oxyfuel can then be beveled with plasma, or pre-cut plasma parts can be cut with ABP on a fiberlaser. Thanks to MicroStep’s unified concept of bevel cutting equipment and easy configuration through patented ACTG® technology, the ABP process is fast, reliable and easily applicable to all cutting technologies: plasma, laser, oxyfuel and waterjet.
