Abstract
A machine for milling pavement such as a road planer or a rotary mixer includes a cutting rotor for penetrating and fracturing a work surface. To adjust the vertical elevation of the cutting rotor, the machine includes a rotor elevation mechanism. The machine may also include a rotor elevation control system that is programmed to lower the cutting rotor to initially contact the work surface. When the cutting rotor initially contacts the work surface, the touch point may be used as a reference to calibrate the rotor elevation mechanism prior to further lowering the cutting rotor into the work surface.
