One of the latest specialty applications with the Nmark SSaM galvo controller involves processing a substrate with two tools simultaneously. This process could be laser marking, laser cutting, laser welding, or other similar industrial laser processes. The challenge is to follow a motion contour on the substrate where that motion contour is larger than the field-of-view of the scan head (primary tool), and then follow the same motion path with a stationary tool (secondary tool) at a variable distance behind the primary laser. In this instance, the galvo scanner is positioned on a bridge above a set of XY stages and the substrate is positioned on top of the XY stages. The secondary tool source is stationary, mounted to the bridge beside the scan head, so that the XY stages must move to position the substrate underneath the secondary tool along the motion contour. The user sends the same trajectory to the scan head and XY stages, but the actual stage motion lags the scanner motion by a user-defined distance to separate the primary and secondary laser processes. The real-time position feedback from the XY stages modifies the scanner trajectory to ensure that the primary and secondary lasers both follow identical paths on the glass. This capability could easily be adapted for a variety of applications including marking, cutting or welding. This level of coordination is possible because the Nmark SSaM scan-head controller resides on the same motion platform as the XY stages, rather than on a separate control architecture, so that all motion and trajectory generation is done by the A3200 motion controller. No other scan-head control solution can match this level of coordination for high-end laser marking, laser cutting, and laser welding operations.
