Abstract
An instantaneous desired cutting position of a milling cutter or circular saw blade in a mobile apparatus for cutting hard materials, such as a concrete highway surface, is maintained even if the mobile apparatus travels over irregular or slanted surfaces. For this purpose the saw blade position is adjustable either by varying the position of the saw blade mounting in a machine frame or by varying the position of the entire machine frame. The position correction is accomplished by a sensor which produces control signals for a position correction power drive in response to pendulum movements which represent cutter or blade deviations from the desired cutting position. The position of the entire machine frame may be varied by raising or lowering a wheel remote from the cutter or blade. Thus, a binding or jamming of the cutter or blade is prevented.
