Addition-measurement-reduction integrated forming system for complex metal component and machining method

The invention relates to the field of additive manufacturing and numerical control machining, in particular to an increase-measurement-reduction integrated forming system for a complex metal component and a machining method. Comprising a basic mechanism, an electric arc material increasing system, a material decreasing system, a tool changing mechanism, a control system, an online data acquisition system and a software part. And meanwhile, the obtained three-dimensional scanning information is used as a blank for subtractive machining, so that the machining precision and the machining efficiency are improved. 本发明涉及增材制造和数控加工领域，特别是涉及一种复杂金属构件的增-测-减一体化成形系统及加工方法。包括基础机构、电弧增材系统、减材系统、换刀机构、控制系统、在线数据采集系统和软件部分，与现有技术性相比，本发明将将增材制造和减材加工整合在一套设备上，一次装夹即可实现增减材一体化成形，同时将获取到的三维扫描信息作为减材加工的毛坯，提高了加工精度和加工效率。
