This Small Business Innovation Research Phase I project will investigate automated inspection and finishing of variable, free-form parts. In turbine blade manufacture, part geometry and finishing work requirements vary part-to-part, so blades must be visually inspected and shaped and polished by hand. The broader research objective is to automate this rigorous and painstaking work by integrating non-contact sensing and a compliant finishing robot in a closed loop configuration. It will analyze part requirements, autonomously generate work plans, remove material with high precision by combining sensory data, and verify work results. Turbine blade manufacture is an essential component of the $34B market in the U.S. for aircraft engines and gas turbine generators, and automated finishing will produce considerable cost savings, quality improvements, and improved worker safety. The current polish-inspect-shape-inspect process cycle will be combined into a single operation, reducing production time plus hardware, footprint, maintenance, and energy requirements. The primary cause of scrap, human error, will be avoided for these valuable, nearly finished parts. Workers will not be tasked with a job that is difficult, dirty, and known to inflict high rates of repetitive stress injuries.

这个小型企业创新研究第一阶段项目将研究可变的自由形状零件的自动检测和精加工。在涡轮机叶片制造中，零件几何形状和精加工要求因零件而异，因此必须对叶片进行目视检查并手工成形和抛光。更广泛的研究目标是通过在闭环配置中集成非接触式传感和柔顺的精加工机器人来自动化这项严格而艰苦的工作。它将分析零件要求，自主生成工作计划，通过结合传感数据高精度地去除材料，并验证工作结果。涡轮机叶片制造是美国340亿美元的航空发动机和燃气涡轮机发电机市场的重要组成部分，自动化精加工将节省大量成本，提高质量，并改善工人安全。目前的抛光-检查-形状-检查工艺周期将合并为一个操作，减少生产时间以及硬件、占地面积、维护和能源需求。对于这些有价值的接近成品的零件，将避免报废的主要原因，即人为错误。工人将不会被分配一项困难，肮脏，并且已知会造成高重复性压力伤害的工作。
