*2.10.1 Application of probing measuring*

Standard applications in micromachining of touch-trigger, on-machine probing measuring systems, has following benefits:


3D touch probes and laser controlled, in process tool management systems are two types of non-contact tool measurement systems that can be used to improve the accuracy and efficiency of CNC machining processes.3D touch probes (as shown in **Figure 14**) are mounted in the machine spindle and can be used for a variety of tasks, including workpiece alignment, datum setting, workpiece measurement, and digitizing 3D surfaces. Laser controlled (as shown in **Figure 15**), in process tool management systems use lasers to measure tool length, diameter, roundness, and run-out with a repeatability of better than 1 μm. These systems can also be used to detect tool wear and to compensate for thermal drift of the machine CNC axis and tool.
