ABSTRACT:
A resistance measuring device is coupled with a controller for controlling the parameters of the cutting process. The device is connected between the laser cutting head of the machine of an electrically conducting part of the laser cutting head and workpiece, and the amount of the electrical resistance of the medium between the laser cutting head and the workpiece can be determined when cutting electrically conducting workpieces. In this method, the amount of the electrical resistance of the medium between the laser cutting head and the workpiece is determined, and the distance between the cutting head and workpiece is also determined. Depending on the detected values of the electrical resistance and distance, the parameters of the cutting process are controlled to obtain efficient cutting action.
