Method and device for contactlessly machining workpieces

摘要

Using the method according to the invention and device according to the invention, a contactless machining tool can be automatically moved over a workpiece at a predetermined distance. A processor (1) actuates the drive (3) for a workpiece (7) in accordance with a predetermined nominal programme value. The instantaneous position of the tool (7) is signalled to the processor (1) with the aid of a pulse generator (8). At the same time, the distance between the tool (7) and the workpiece is measured by means of a distance measuring device (10). The deviation from an ideal value is signalled including sign after frequency conversion in the form of pulses via a mixer (9) to the processor (1) and is thus used for accelerating the correct setting of the tool (7) (Figure 1). <IMAGE>
