Problems solved by technology

[0002] Please refer to the Chinese Taiwan invention patent I508810 "Laser Assisted Processing Device", which divides the main laser beam from the laser generating unit into multiple laser sub-beams by means of a beam splitting module, and these laser sub-beams are constantly irradiated on multiple laser beams by the tool. The processing area defined by the cutting edge, since the laser sub-beams rotate synchronously with the tool, the laser sub-beams will continue to heat the annular processing area around the tool, so these laser sub-beams will not only heat and soften the workpiece in front of the tool , will also heat and soften the workpiece located behind the tool, thus possibly causing a qualitative change in the processed workpiece

Embodiment Construction

[0030] see figure 1 , a laser preheating control method 10 of the present invention includes "the laser controller obtains the moving direction of the tool on the workpiece" 11 and "the laser controller forms the laser spot only in the area to be preheated according to the moving direction of the tool" 12 .

[0031] see figure 2 and image 3 , the laser preheating control method 10 is applied to the laser preheating control device 100, the laser preheating control device 100 has a laser source 110 and a laser controller 120, the laser source 110 is used to output the laser beam to the workpiece 200, when the tool 300 When processing the workpiece 200 along the processing path, the laser beam and the tool 300 move relative to the workpiece 200 synchronously, and the laser beam selectively forms a laser spot on the surface of the workpiece 200. In this embodiment, the tool 300 and The laser source 110 is arranged on the machining spindle 410 of the machine tool 400. The tool ...

Abstract

The invention relates to a laser preheating control method which is applied to a laser preheating control device. When a cutter is used for processing a workpiece along a processing path, a laser source of the laser preheating control device outputs a laser light beam to the workpiece; a laser facula is selectively formed in the surface of the workpiece; according to the moving direction of the cutter on the workpiece, a laser controller of the laser preheating control device enables the laser facula only to form in a region to be preheated in the front part of the processing path, so that theworkpiece in the front part of the processing path is preheated, and the situation that the quality is changed caused by that the workpiece at the rear part of the processing path is heated once again can be avoided.

Description

technical field [0001] The invention relates to a laser preheating control method and a laser preheating control device, in particular to a laser preheating control method and a laser preheating control device which can avoid qualitative changes of workpieces caused by repeated heating. Background technique [0002] Please refer to the Chinese Taiwan invention patent I508810 "Laser Assisted Processing Device", which divides the main laser beam from the laser generating unit into multiple laser sub-beams by means of a beam splitting module, and these laser sub-beams are constantly irradiated on multiple laser beams by the tool. The processing area defined by the cutting edge, since the laser sub-beams rotate synchronously with the tool, the laser sub-beams will continue to heat the annular processing area around the tool, so these laser sub-beams will not only heat and soften the workpiece in front of the tool , will also heat and soften the workpiece located behind the tool,...
