Zusammenfassung:	An apparatus for force monitoring and control of a multi-axis router. The spindle assembly has a mounting plate that is attached to a base plate in the router assembly through three equally spaced load cells. The load cells are maintained in tension because the spindle assembly is suspended below the base plate. The center of gravity of the spindle assembly is in the center of the three load cells. Forces on the cutting tool are measured by the load cells, which are monitored by a controller that determines the load on the cutting tool. The feed rate of the cutting tool is adjusted based on the calculated cutting tool force. Abnormal conditions, such as an unbalanced or dull tool, are determined from the measured forces.
