Abstract�� Temperature field in the laser bending process was numerically simulated by MSC. Marc software. Variations of temperature with time to cause sheet metal bending were calculated. Simulation result was verified by the temperature on the lower surface of the sheet metal, which was measured by the thermocouple temperature t ransducer measuring under the laser scanning line. Experimental curves of temper ature versus time are in agreement with simulation results. The simulation resul ts can be regarded as a basis for choosing laser technological parameters.
Keywords�� thin plates   laser bending   temperature field   numerical simulation
