<p>Electronic control apparatus utilisable with milling and cutting machines and the like, to obtain constant-depth cuts, independently on surface undulations and/or unevenness of the material being worked (5), constituted by an internally hollow plate (1) with a perforated bottom, coaxial to the tool and connected to a pressurised air source (7), suitable to constitute an air pad between the plate (1) and the material (5), said plate being anchored to a floating device suitable to follow the undulations of the surface, of the material and to a mechanical device of precision to sense the surface undulations; an electronic device (13) that senses the vertical deviations of the floating device and transmits the same to a control processor (14) suitably programmed to regulate the vertical position of the tool (2). <IMAGE></p> |
