摘要： The invention relates to a method for setting at least one predetermined distance between a machine tool (10) and a metallic or non-metallic electrically conductive workpiece (12) according to which a capacitive and/or inductive sensor (16) is fixed to the machine tool (10) while facing the workpiece (12). The machine tool (10) is displaced with constant speed toward the workpiece (12) by means of a drive device, and a sensor signal is output at predetermined time intervals by means of a data processing unit (24). Said sensor signal has a characteristic quantity that continuously changes in a non-linear manner according to the distance of the machine tool (10) from the workpiece (12). The invention provides that the data processing unit (24) 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. In addition, a limit difference that characterizes the predetermined interval is stored in the data processing unit (24), and the movement of the machine tool (10) is stopped when the magnitude of the difference of the compared values exceeds the limit difference.

摘要： Die Erfindung betrifft ein Verfahren zur Überwachung eines Brennschneidprozesses (10), welcher eine Vorheizphase (12), eine auf die Vorheizphase (12) folgende Lochstechphase (14) und eine auf die Lochstechphase (14) folgende Schneidphase (16) aufweist, wobei ein Schneidbrenner ein elektrisch leitendes Werkstück mit einer durch Verbrennung einer Gasmischung erzeugten Flamme beaufschlagt und wobei ein zwischen einem elektrisch leitenden Teil des Schneidbrenners und dem Werkstück fließender elektrischer Strom (I) mittels eines Strommessgeräts während eines Messzeitraums (18) gemessen wird. Erfindungsgemäß ist vorgesehen, dass ein Zündpunkt (20), an dem das Durchstechen eines Lochs durch das Werkstück mittels der Flamme durch Oxidation des Werkstücks beginnt, durch eine Änderung des gemessenen Stroms (I) detektiert wird.
