Fives is a multinational network of over 100 companies, with a total of 8,400 employees. Fives Liné Machines(FLM), one of these companies, is based in Granby and manufactures gantry-style machine tool solutions forthe aerospace, rail and heavy equipment industries. Last year, FLM launched the Liné Machines Robotics lineof custom-made solutions focusing on seven core processes: milling, trimming and drilling; deburring andpolishing; cleaning and surfacing; forming inspection and scanning; automation, tooling and part holding; andperipheral equipment for machine tools.FLM is interested in acquiring expertise in the use of industrial robots for machining purposes. The companyis particularly interested in using Fanuc's F-200iB hexapod as a fixture for holding a workpiece that is beingmachined. However, since FLM is focusing on the aerospace sector, it needs a hexapod that can position itsmobile platform with high absolute accuracy. Unfortunately, neither Fanuc, nor any other service provided,offers means for increasing the accuracy of a hexapod.The main objective of this project is to develop a method for improving the accuracy of Fanuc's F-200iBhexapod, by calibrating it and modelling its stiffness. A secondary objective will be to assess the possibility ofusing an array of such hexapods as means for flexible fixturing.

Fives 是一个由 100 多家公司组成的跨国网络，共有 8,400 名员工。 Fives Liné Machines (FLM) 是其中之一，总部位于格兰比，为航空航天、铁路和重型设备行业制造龙门式机床解决方案。去年，FLM 推出了 Liné Machines Robotics 系列定制解决方案，专注于七个核心流程：铣削、修边和钻孔；去毛刺和抛光；清洁和铺面；成型检验和扫描；自动化、工具和零件固定； FLM 有兴趣获得使用工业机器人进行加工的专业知识。该公司对使用 Fanuc 的 F-200iB 六足机构作为固定正在加工的工件的夹具特别感兴趣。然而，由于 FLM 专注于航空航天领域，因此需要一个能够以高绝对精度定位其移动平台的六足机构。不幸的是，Fanuc 或提供的任何其他服务都没有提供提高六足机器人精度的方法。该项目的主要目标是开发一种通过校准和建模其刚度来提高 Fanuc F-200iBhexapod 精度的方法。第二个目标是评估使用一系列此类六足机构作为灵活固定装置的可能性。
