生物医学应用对离散自由曲面零件的需求不断扩大，强调了对单点渐进成形等灵活生产工艺的需求。本文介绍了使用医用级钛板设计和制造锁骨植入物过程中遇到的具体挑战。这些植入物的骨折固定和骨对齐任务要求特定的精度分布，而独特的几何形状和后成形热处理影响生产精度。考虑到2级钛的成形角和软组织相互作用，这些植入物的设计潜力进行了讨论。介绍了钛锁骨固定板的设计、成型、热处理和修整的一般情况。
The expanding demand for discrete freeform parts in bio-medical applications emphasizes the need for flexible production processes like Single Point Incremental Forming. This paper presents the specific challenges encountered during the design and fabrication of clavicle implants using medical grade titanium sheets. The fracture fixation and bone aligning task of these implants call for specific accuracy distribution, while the distinct geometry and post forming heat treatment influence production accuracy. The design potential for these implants considering forming angles of titanium grade 2 and soft tissue interactions are discussed. A generic case for the design, forming, heat treatment and trimming of a Titanium clavicle fixation plate is presented.
