摘要
综述了电子束熔丝增材制造过程在线监控的研究现状,集中讨论成形过程熔池形貌监测、成形过程温度场监测、流动场监测,着重介绍了对熔池形貌的在线监测,并展望了电子束熔丝增材制造过程在线监测未来可能的发展方向:(1)制造过程中电子、离子等信号的在线监测;(2)引入新的信号进行在线监测;(3)对每一层堆积体的质量和层高进行实时跟踪;(4)多信号协同在线监测。
In this paper, the development status of on-line monitoring for the electron beam freeform fabrication are introduced, mainly focusing on the monitoring of the molten pool morphology, the temperature field of forming process and the flow field, with emphasis on the monitoring of the molten pool morphology during the manufacture. At the same time, the prospects of on-line monitoring for the electron beam freeform fabrication are presented, (1) online monitoring the signals of electronic and ion; (2) introduce new signals for online monitoring; (3) real-time tracking each layer's the quality and height of deposit body; (4) multi-signal collaborative online monitoring.
