Measuring Tool Lengths on a Fanuc OM CNC Machine

This video shows how easy it is to measure the lengths of the tools in a CNC Mill. This is very useful for machines with tool changers that allow different cutters to be installed without doing a Z offset measurement every tool change (some CNC routers do this). Both tool numbers 1 and 3 are measured in this video. Re-doing the zero reference measurement is helpful every time because there could be some inaccuracies if the dial indicator is moved too far.
