A dual-channel laser additive manufacturing CNC system

Abstract

The invention discloses a dual-channel laser additive manufacturing numerical control system. The system includes a control system, a data acquisition system, an online monitoring system and an HMI unit, wherein: the control system adopts a bus-based multifunctional module design, including a core Control unit, axis control unit, position feedback unit, digital input and output control unit; data acquisition system integrates analog acquisition card, digital I / O acquisition card; online monitoring system includes industrial computer, CCD high-speed camera, infrared imager; all The HMI unit is connected to the control system, and includes a liquid crystal screen, a full-function keyboard and a lower operation panel, which are used to input process parameters, edit processing programs, and display deposition axis / movement axis position coordinates and alarm information. The above system can improve the ability to analyze the data combined with the dual-channel processing technology during the additive manufacturing process, and monitor the processing status in real time to improve the processing quality.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a dual-channel laser additive manufacturing numerical control system. Background technique [0002] At present, additive manufacturing, also known as 3D printing technology, is a fusion of computer-aided design, material processing and molding technology, based on digital model files, through software and numerical control systems. Special metal materials, non-metal materials and medical biological materials, The manufacturing technology of manufacturing physical objects by stacking layer by layer according to extrusion, sintering, melting, light curing, spraying, etc. Compared with the traditional subtractive manufacturing processing mode, which removes, cuts, and assembles raw materials, it is a "bottom-up" manufacturing method that accumulates materials from scratch, which makes it constrained by traditional manufacturing methods in the past. And it becomes pos...

Problems solved by technology

Compared with the traditional subtractive manufacturing processing mode, which removes, cuts and assembles raw materials, it is a "bottom-up" manufacturing method through material accumulation, starting from scratch, which made it constrained by traditional manufacturing methods in the past. The manufacture of complex structural parts that cannot be realized becomes possible

[0003] However, the existing technology has the defects of low processing efficiency and long construction period for processing large structural parts in the process of laser additive manufacturing, and it is impossible to control the dual channels at the same time when performing adaptive control, which restricts the development of additive manufacturing technology.
