Abstract

The invention provides a double-beam laser heating auxiliary drilling integration device and method, and belongs to the technical field of machining. The double-beam laser heating auxiliary drilling integration device comprises a continuous laser generation system and a pulse laser generation system, wherein the continuous laser generation system comprises a continuous laser generator and a continuous laser focusing head; a manipulator clamps the continuous laser focusing head to move so as to adjust the irradiation direction of a continuous laser beam, the size of a laser spot, the laser movement speed and the distance between the center of the laser spot and the surface of a workpiece; the pulse laser generation system comprises a pulse laser generator and a collimation system which areconnected with each other; and the pulse laser beam irradiates the surface of the workpiece from the interior of a drill bit along a drill tip through the collimation system. Compared with single-beamlaser heating, the double-beam laser heating auxiliary drilling integration device and method have higher machining efficiency and lower surface damage, drilling machining of transparent materials difficult to machine is realized, and the cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of mechanical processing, in particular to an integrated device and method for dual-beam laser heating-assisted drilling. Background technique

[0002] Laser heating assisted cutting technology is to focus a high-power laser beam on the surface of the workpiece in front of the cutting edge. In a short time before the material is cut, the local heating is heated to a very high temperature to change the machinability of the material at high temperature, and then Use conventional tools for processing. By heating the material in a small local area, the plasticity of the material is improved while the hardness of the material is reduced, the cutting force is reduced, the service life of the tool is extended, the formation of surface damage is suppressed, and cutting chatter is prevented, so as to improve processing efficiency, reduce cost, The purpose of improving surface quality. For hard and brittle ceramics ...
