摘要：An impending kickback condition in the operation of a power tool or machine tool system is nd and ud to control or eliminate the kickback. The ability to n an impending kickback condition can be ud in all categories of power driven tools. The change in force applied to the power driven tool or other implement is monitored by measuring the rate of change of speed of the tool or implement, and if the speed is decreasing, the rate of change of speed is compared with a threshold value which may be either pret or variable. If this threshold value is exceeded, an output control signal is generated which inhibits the coupling of power to the tool or other implement and/or applies a brake to stop the tool or implement. In order for power to once again be coupled from the motive.power source to the shaft, the start switch must be opened and then reclod or some other signal provided by the operator or another predetermined condition must be met.
