A 3D processing method and 3D processing equipment

Abstract

The invention discloses a 3D processing method and 3D processing equipment. The 3D processing method comprises: a laser additive cladding system performs 3D printing to obtain a 3D printing unit; an image acquisition unit acquires image information of the 3D printing unit and sends it to the image Processing unit; the image processing unit judges whether the 3D printing unit needs to be cut, and if so, drives the cutting processing unit to cut the 3D printing unit; otherwise, drives the laser additive cladding system to continue 3D printing. The 3D processing method and processing equipment of the present invention combine the laser additive molding system with the multi-axis processing system. During the 3D printing process, the image of the 3D printing unit is collected, and the 3D printing unit is accurately processed by the cutting processing unit. Cutting can realize the controllability and adjustment of laser cladding 3D printing forming parts, avoid the defects of forming failure and low forming precision caused by blind welding, and realize the efficient and high-precision processing of 3D workpieces.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D processing method and 3D processing equipment. Background technique [0002] In recent years, laser cladding 3D printing technology has developed rapidly due to its flexible and efficient manufacturing of complex parts. The parts manufactured by it have the advantages of good metallurgical quality, fast forming speed and large forming size, but the smoothness and precision of the formed parts are low, especially the matching position cannot guarantee the accuracy, which is the most difficult for laser cladding 3D printing technology to be industrialized on a large scale. Important factor. [0003] In order to improve the forming accuracy of laser cladding 3D printing technology, the conventional method is to increase the convergence of the laser beam, reduce the size of the printing point, and improve the forming accuracy, but it is still difficult to achieve the cuttin...

AI Technical Summary

Problems solved by technology

At present, most of the 3D printing processes at home and abroad adopt the "blind" printing process, which needs to summarize a large amount of process data. The forming process is complicated, and often every shape part and every material needs continuous testing. Almost every layer It is necessary to summarize the process parameters; and when an abnormality occurs during the molding process, the system cannot recognize it and cannot automatically adjust it. Without manual intervention, it will result in failure to continue molding or leave defects in the workpiece. Experienced professional technicians must Personnel operate the machine to observe the molding status at any time to make more qualified parts, which seriously affects the popularity of metal 3D printing
