A system for processing a workpiece, including a rotary drive having a path along which a flow of a fluid is established during operation, a sensor in communication with the path, to generate a signal responsive to the flow of the fluid and not to generate the signal responsive to an absence of the flow, and a controller communicatively coupled to the sensor to enable the operation of the rotary drive subsequent to a termination of the signal if a duration interval thereof is greater than or equal to a predetermined value, and to prevent the operation if the duration interval of the signal is less than the predetermined value. The rotary drive may include a drill.
