Auto Focus Measurements The Auto Focus mode can be used to conduct feature measurements in the optimum focal plane. When performing Auto Focus measurements, the system determines the z-axis position of optimum part focus before collecting feature data points. In manual systems, the user sweeps back and forth through the range of focus by raising and lowering the z-axis. When the optimum point of focus has been found, a point at the center of the crosshair will be probed. Auto Focus points are probed using the standard or active crosshair in manual systems. In CNC enabled systems, the system drives the z-axis to the optimum focus point automatically and any of the available probes can be used for autofocus measurements. In CNC enabled systems, and Auto Focus measurement steps are included in M3 part programs.
Auto Focus Measurements in Manual Systems To perform Auto Focus measurements in a manual system: 1 Select the standard or active crosshair probe from the probe menu.
