Research Progress of Monitoring and Control Technology for Metal Additive Manufacturing

金属增材制造技术凭借其柔性化定制能力和复杂构件成形优势,有望成为提升航天领域设计与制造能力的一项关键核心技术,但现阶段该方法仍然存在制造过程稳定性不足、制造质量实时检测困难、工艺参数实时调节技术成熟度有待提升等问题。本文从增材过程信息感知、增材工艺优化决策、质量优化控制发展趋势三方面详细阐述了金属增材制造监测技术的研究进展,论证了高性能结构件增材成形过程中工艺变量-过程参量-成形质量调控的发展必要性,并就增材过程监测技术的发展趋势做出了思考与展望。

Metal additive manufacturing technology is growing rapidly and expected to play a key role in design and manufacture of aerospace component,which is attributed to its ability of personalized customization and advantages of forming complex components. However,there is insufficient technical maturity in additive manufacturing stability,real-time quality monitoring,real-time process adjusting in the recent process of additive manufacturing. To solve these problems,the research of metal additive manufacturing monitoring and control technology is summarized from three aspects:Process monitoring,parameter optimizing and closed-loop control. Meanwhile,the necessity of intelligent control of process parameters/sensor data/forming quality in additive manufacturing of high-performance metallic components is demonstrated and future research of process monitoring technology in metal additive manufacturing is suggested.
