Abstract: A system for and methods of performing lateral measurements of a work fixed to an XY translation stage of a CNC machine comprises coupling a range-detecting laser scanner to a tool mount of the CNC machine that is translatable along the X, Y, and Z axes. The work is surrounded by reflectors that are coupled to the XY translation stage, preferably parallel to the X and Y axes. The laser scanner is initially positioned at a predetermined coordinate, and its laser output is directed toward one of the reflectors. The distance from the laser scanner to the work is measured and is correlated with the laser scanner position to determine a coordinate of the work. The scanner is then incremented along one of the X and Y axes and another coordinate of the work is determined. The periphery of the work is similarly scanned, and the lateral measurements are determined therefrom.
