Laser processing method and corresponding laser machining apparatus

The present invention relates to laser machining process and equipment. The laser machining process includes the following steps; setting the workpiece onto the working bench, heating the machined area of the workpiece to preset temperature, and machining the heated machined area with laser beam. The laser machining equipment includes one working bench for bearing the workpiece, one laser source to emit laser beam, and one heating source to preheat the machined area of the workpiece to preset temperature and reduce the temperature difference between the temperature of the machined area and the high temperature the laser beam generates.
