Abstract
A method is for setting at least one predetermined distance between a machine tool () and a metallic or non-metallic electrically conductive workpiece (12) according to which a capacitive and/or inductive sensor () fixed to the machine tool () while facing the workpiece (). The machine tool () is displaced with constant speed toward the workpiece () by means of a drive device, and a sensor signal is output at predetermined time intervals by means of a data processing unit (). The sensor signal has a characteristic quantity that continuously changes in a non-linear manner according to the distance of the machine tool () from the workpiece (). The data processing unit () compares each read out value of the characteristic quantity with a comparative value read out before at a predetermined number of time intervals and calculates the difference between the values that are compared with one another.
