摘要： Systems, devices, and methods for additive manufacturing are provided that allow for components being manufactured to be assessed during the printing process. As a result, changes to a print plan can be considered, made, and implemented during the printing process. More particularly, in exemplary embodiments, a spectrometer is operated while a component is being printed to measure one or more parameters associated with one or more layers of the component being printed. The measured parameter(s) are then relied upon to determine if any changes are needed to the way printing is occurring, and if such changes are desirable, the system is able to implement such changes during the printing process. By way of non-limiting examples, printed material in one or more layers may be reheated to alter the printed component, such as to remove defects identified by the spectrometer data. A variety of systems, devices, and methods for performing real-time sensing and control of an additive manufacturing process are also provided.

摘要： A high-efficiency and high-precision combined machining apparatus for a diamond wafer sheet and a combined high-efficiency and high-precision method for machining a diamond wafer sheet are disclosed. The apparatus can comprise a machining motion platform component installed on a base, a laser machining component, a grinding component, a polishing component and a detection component installed on a support frame. In operation, a high-energy laser beam of the laser machining component can focus on the surface of the diamond wafer sheet to be machined and perform a straight reciprocating irradiation on the diamond wafer sheet, thereby realizing the planarization machining of the diamond wafer sheet. Further, the grinding component and the polishing component realize further high-precision grinding planarization and finishing polishing machining under the action of the laser machining component.
