关于客户
本案例中的客户是利用激光束熔化 (LBM) 技术来制造复杂金属零件的任何行业或组织。这包括但不限于航空航天业。这些客户经常面临 LBM 工艺的挑战,特别是在工艺过程中发生的热机械现象方面。熔化材料产生的热量必须消散,并且焊接路径收缩产生的力必须得到补偿。这通常需要向零件添加支撑几何形状,这会增加材料的使用并需要额外的后处理。工艺的稳定性在很大程度上取决于这些支撑结构,如果支撑结构不够,零件的质量和形状可能会偏离预期结果。
挑战
激光束熔化 (LBM) 技术可以在不浪费材料的情况下制造复杂的金属零件,并在航空航天等行业得到应用。然而,该过程本质上是一种微焊接过程,热机械现象起着重要作用。熔化材料产生的热量必须消散,并且焊接路径收缩产生的力必须得到补偿。为了保持温度并使零件附着在打印板上,需要在零件上添加额外的支撑几何形状。这不仅增加了材料的使用,而且还需要额外的后处理。过程稳定性在很大程度上取决于支撑结构。如果支撑不够坚固或不能有效导热,零件的质量和形状可能会偏离预期结果。在此过程中支撑物破裂可能会导致流程中止,从而可能使每个零件的成本增加一倍,特别是对于首次打印的零件。
解决方案
Additive Works 旨在通过过程模拟和优化来取代支持生成过程中涉及的大量迭代。 Amphyon 软件即将推出的支撑模块可确保不超过临界值,并相应地自动创建支撑几何形状。所应用的例程优化了薄壁支撑结构的空间变化参数,允许在具有高机械负载的关键区域中形成密集的支撑壁,以及在粉末可去除性更重要的情况下具有大穿孔的粗糙壁。计算出最佳支撑参数后,软件可以自动生成相应的支撑结构,包括零件和支撑之间的接口,其尺寸可确保稳定的工艺并最大限度地减少后处理工作。该软件还可以自动生成一次成功的 LBM 支撑结构,从而节省材料并减少所需的构建时间。这种模拟驱动的工作流程需要显着减少用户交互,降低关键部件的流程开发成本,并在 LBM 中引入最先进的支持生成自动化。

Airbus Soars with Wearable Technology
Building an Airbus aircraft involves complex manufacturing processes consisting of thousands of moving parts. Speed and accuracy are critical to business and competitive advantage. Improvements in both would have high impact on Airbus’ bottom line. Airbus wanted to help operators reduce the complexity of assembling cabin seats and decrease the time required to complete this task.

Aerospace & Defense Case Study Airbus
For the development of its new wide-body aircraft, Airbus needed to ensure quality and consistency across all internal and external stakeholders. Airbus had many challenges including a very aggressive development schedule and the need to ramp up production quickly to satisfy their delivery commitments. The lack of communication extended design time and introduced errors that drove up costs.

Accelerate Production for Spirit AeroSystems
The manufacture and assembly of massive fuselage assemblies and other large structures generates a river of data. In fact, the bill of materials for a single fuselage alone can be millions of rows of data. In-house production processes and testing, as well as other manufacturers and customers created data flows that overwhelmed previous processes and information systems. Spirit’s customer base had grown substantially since their 2005 divestiture from Boeing, resulting in a $41 billion backlog of orders to fill. To address this backlog, meet increased customer demands and minimize additional capital investment, the company needed a way to improve throughput in the existing operational footprint. Spirit had a requirement from customers to increase fuselage production by 30%. To accomplish this goal, Spirit needed real-time information on its value chain and workflow. However, the two terabytes of data being pulled from their SAP ECC was unmanageable and overloaded their business warehouse. It had become time-consuming and difficult to pull aggregate data, disaggregate it for the needed information and then reassemble to create a report. During the 6-8 hours it took to build a report, another work shift (they run three per day) would have already taken place, thus the report content was out-of-date before it was ever delivered. As a result, supervisors often had to rely on manual efforts to provide charts, reports and analysis.
