This Small Business Technology Transfer (STTR) Phase II research project focuses on the development of an innovative Multi-Axis Planning System (MAPS), for layered manufacturing processes. By enabling current direct metal deposition systems to fully control and utilize multi-axis capability to make complex parts, MAPS will enable fully-automated process planning for multi-axis layered manufacturing processes to directly control metal deposition machines used in automated fabrication. The building of complicated shapes without support structures is a major challenge for current direct metal deposition processes. This proposed Phase II research will continue to research and develop the 'centroidal axis' algorithm in multi-axis slicing, with an emphasis on completeness and robustness for complicated shapes such as geometry with multiple loops and internal structures. This algorithm will allow manufacturing systems to handle parts with multiple loop features. Additional features to be developed under this Phase II project include a deposition visibility map for efficient computation on the collision-free slicing/deposition sequence in a multi-axis scenario, and a '3-D layer' toolpath generation which will provide an alternative turning algorithm for the deposition process.The proposed project will impact the manufacturing industry by incorporating fully-automated multi-axis control capability into the rapid manufacturing industry to produce fully functional metal parts with complicated shapes. This capability will lead to dramatic reductions in lead time and manufacturing costs for high-value, low-volume components with high performance material. Assuming the outcomes are successful, the project will several segments such as aerospace, military, motor sports, automotive, industrial machinery, medicine, dentistry, and consumer products.

这个小企业技术转让（STTR）第二阶段研究项目的重点是开发一个创新的多轴规划系统（MAPS），分层制造过程。通过使当前的直接金属沉积系统能够完全控制和利用多轴能力来制造复杂零件，MAPS将实现多轴分层制造工艺的全自动工艺规划，以直接控制自动制造中使用的金属沉积机器。在没有支撑结构的情况下构建复杂形状是当前直接金属沉积工艺的主要挑战。这项拟议的第二阶段研究将继续研究和开发多轴切片中的“质心轴”算法，重点是复杂形状（如具有多个循环和内部结构的几何形状）的完整性和鲁棒性。该算法将允许制造系统处理具有多个回路特征的部件。在第二阶段项目下开发的其他功能包括沉积可见性图，用于在多轴场景中有效计算无碰撞切片/沉积序列，以及一个“三维层”刀具路径生成，这将为沉积过程提供一种替代的车削算法。拟议的项目将通过将全自动多功能轴控制能力应用于快速制造行业，以生产具有复杂形状的全功能金属零件。这种能力将大大减少使用高性能材料的高价值、小批量组件的交货时间和制造成本。假设结果是成功的，该项目将涉及航空航天、军事、赛车运动、汽车、工业机械、医药、牙科和消费品等几个领域。
