Abstract:
A system and apparatus for cutting grooves in a surface includes a housing having a rotatable cutting head mounted therein. An actuator drives the cutting head out of and into contact with the surface. Sensors disposed on the housing sense a depth of the groove cut by the cutting head. A controller is arranged to receive a signal from the sensors and compare the depth of the groove with a predetermined reference depth. The controller sends a signal to the actuator and adjusts the position of the cutting head via the actuator to maintain the depth of the groove at about the reference depth.
