Paper Abstract

The article presents a developed, proprietary system of automatic temperature control of the workpiece surface for a laser processing. In the control system, a regulator based on fuzzy logic algorithms has been developed. The system is based on a RT real time system with a frequency of 1 kHz. In order to implement the system, the reconfigurable NI CompactRio microprocessor system together with the appropriate input modules was used. The control application was created based on the LabView software. The feedback signal for the control system was realized with usage of a fiber optic pyrometer observing the area of the laser beam. In order to implement the system in the existing, dedicated control system of the Trumpf TruCell 1005 laser device, a number of integration works were carried out. During the preliminary tests, the settings of the developed regulator were selected empirically and the correctness of its operation was checked for various working conditions. The article also presents the time series of the temperature control value and the control error combined with the course of the modulated laser device power during the laser machining process.
