Abstract
The performance of the laser positioning system was much worse. The system consistently positioned the beam short by a significant amount at the edges of the workspace. A designed artifact was produced, and used to evaluate the laser performance against a set of tolerance controls extracted from the ASME Y14.5-2009 Standard. The largest scatter of values was observed on the position of small circular features located over the working area. The largest tolerance magnitude (239â¯Î¼m) was calculated as the combined effect of location, orientation, size and form errors in the trace of a large quadrifolium etched over the working area of the laser. The errors measured in this research are substantial.
