The research objective of this award is to understand the relationships and interactions when combining additive and then subtractive direct manufacturing techniques so that the sequential combination yields the advantages of both production techniques without incurring significant disadvantages. Two specific objectives are: 1) To identify the part geometry inaccuracy and shrinkage in order to establish material allowance during additive processing, and 2) To identify and create mathematical and physical models for setup to account for location error due to the nature of direct metal fabrication surfaces. If successful, this work will provide a rapid capability to make parts with complex freeform geometries as provided by function free-form additive systems, while providing exacting tolerance control and material properties, as provided by computer numerically controlled machining by using these processes sequentially and automatically. This research will lead to a new technology that would create service parts and prototypes for next-generation complex mechanical part systems with the specified material properties, to the exacting tolerances and advanced geometries as desired, and do so in an automated manner with little or no human intervention required.

该奖项的研究目标是了解在结合增材和减材直接制造技术时的关系和相互作用，以便顺序组合产生两种生产技术的优点，而不会产生重大缺点。 两个具体目标是：1）识别零件几何形状不准确性和收缩，以便在增材加工期间建立材料余量，以及2）识别并创建用于设置的数学和物理模型，以考虑由于直接金属制造表面的性质而引起的位置误差。 如果成功的话，这项工作将提供快速的能力，使零件具有复杂的自由形状的几何形状所提供的功能自由形式的添加剂系统，同时提供严格的公差控制和材料性能，所提供的计算机数控加工通过使用这些过程顺序和自动。 这项研究将带来一种新技术，该技术将为下一代复杂的机械零件系统创建服务零件和原型，这些零件具有指定的材料特性，严格的公差和所需的先进几何形状，并且以自动化的方式进行，几乎不需要人工干预。
