Abstract
Woodworking machines and safety methods for use with those machines are disclosed. The machines include a detection system adapted to detect one or more dangerous conditions between a person and the cutting tools, and a reaction system associated with the detection system. The reaction system is configured to retract the cutting tool at least partially away from the cutting region upon detection of a dangerous condition by the detection system.
Claims1
A method for minimizing potential injuries from a woodworking machine having a movable cutting tool, the method comprising:
- detecting accidental contact between a person and the cutting tool;
- and
- retracting the cutting tool away from the person in the event accidental contact between the person and the cutting tool is detected;
- where the cutting tool rotates and has angular momentum, and where the step of retracting includes using at least a portion of the angular momentum of the cutting tool to retract the cutting tool away from the person.
