Improve tool life of CNC machining center by precision tool wear detection.

Since the real-time and accurate wear is updated, it improves the tool life.

Machining accuracy will be always maintained within tolerance.

Due to auto-tool measuring and updating the wear of the tools, the accuracy on WORK PIECE will be always maintained with-in tolerance.

Reduction in rejection by tool breakage detection.

Due to timely tool breakage detection, the further damage to other tools or the component is avoided.
