Datron Dynamics, Inc. (Milford, NH) released a vision system for high-speed machining applications—the Datron IVS (Integrated Vision System), which is housed in a rugged metal chassis for industrial applications. It is mounted to the Z-axis of its machining centers for locating fiducials and crop marks. As the camera moves to a pre-defined location or window, it identifies fiducials (crop marks or tick marks) within a 20mm area and feeds offset data into the machine’s Microsoft Windows-based control software. Any edge-to-fiducial irregularities are fed into the machining data and compensated for, dynamically, before the machining begins. Further, by locating multiple fiducials the system can automatically adjust for skew or image-to-edge variance. With Datron IVS, set up is easy and fast. The operator places the part on the bed, perhaps using Datron's proprietary VacuMate™ (vacuum table) workholding or a fixture with pins. The pins insure that the part is on the fixture properly. The camera then scans for fiducials, edges and images and feeds the data into Datron’s Microsoft© Windows©-based control software. Irregularities are compensated for dynamically before the machining starts, ensuring quality and uniformity. If the camera determines that the part is not positioned correctly then the program automatically pauses and asks the operator to abort or retry. Or, the software can adjust for the variance and cut usable parts even when the blank is not positioned properly.
