摘要
金属增材制造技术在航空航天、医疗等多个领域得到广泛应用,但仍面临着零件裂纹、空隙和翘曲等很多质量缺陷问题。在早期阶段对成形部分零件进行质量检验,发现成形过程中的缺陷,通过反馈控制调节参数来修复缺陷或者中止加工过程,这是非常有必要的。研究了结构光三维测量技术及相关的一些关键技术,并基于这些技术开发了一种可以用于监测粉末床熔融制造过程的在线测量系统。
Metal additive manufacturing technology had been widely used in aerospace, medical and other fields. However,it still faces many quality defects such as cracks, voids and warping. It is very necessary to carry out quality inspection on part of forming parts in the early stage, discover defects in forming process, and repair defects or abort machining process by feedback control adjustment parameters. Based on the three dimensional structure light measurement technology and some related key technologies, an online measurement system for monitoring the melting process of powder bed is developed.
