Kickback detection system

摘要

A method of detecting a kickback event for a table saw includes operatively connecting a stress sensor to the table saw that is configured to detect a characteristic of a work component of the table saw, the work component being coupled to a workpiece being cut by the table saw during a cutting operation. The stress sensor outputs stress signals indicative of the characteristic of the work component. A speed of the saw blade is then controlled based on the stress signals.

1. A method of detecting a kickback event for a table saw, the table saw including a motor having an arbor shaft for driving a saw blade and a guide fence for guiding a workpiece, the method comprising:
operatively connecting a stress sensor to the table saw, the stress sensor being configured to detect deflection of a work component during a cutting operation, the work component comprising at least one of the arbor shaft and the guide fence; outputting sensor signals from the stress sensor indicative of the deflection of the work component; and controlling the saw blade based on the sensor signals.
