Combined Laser Additive Manufacturing and Subtractive Surface Finishing (CLASS)

激光粉末床融合（PBF）是一种新兴的制造方法，可以直接从计算机辅助三维设计中生产净形状和功能产品。这些部件是通过材料层的连续应用和巩固而建造的。为了在制造业中被广泛接受，仍然有相当多的硬件相关问题需要解决，包括但不限于；残余应力，表面纹理和表面精加工的方法，这些问题随着加工速度的加快和应用于更大的零件而加剧。通过数字集成捕获过程中数据的能力将进一步验证AM工艺在受法规标准控制的零件生产中的接受程度，其中工艺记录是必需的。该项目的目的是生产一个金属增材制造机器平台，其子系统将来可扩展到仪表级，能够减少增材制造过程中产生的残余应力，并将在零件制造过程中进行非接触式精加工。多台机器也将通过传感器进行数字连接和监控，以实时了解全球连接的制造设施。

Laser powder bed fusion (PBF) is an emerging manufacturing approach to produce net shapesand functional products directly from computer aided three dimensional designs. The parts arebuilt by the consecutive application and consolidation of material layers. In order to becomemore widely accepted within manufacturing, there are still considerable hardware associatedissues which need to be resolved including but not restricted to; residual stress, surfacetexture and methodologies for surface finishing, these problems are exacerbated as theprocess gets faster and is applied to larger parts. The ability to capture in -- process data bydigital integration will further validate the acceptance of the AM process in the production ofparts which are controlled by regulatory standards, where process records are required.The aim of this project is to produce a metal AM machine platform, the subsystems of which arescalable in future to meter class, which is capable of reducing the residual stresses developedduring the AM build, and that will perform in process non-contact finishing on parts as they arebuilt. Multiple machines will also be digitally connected and monitored via sensors for real-timeinsights across a cohort of globally connected manufacturing facilities.
