Visually-Guided Robotic Machining of Complex Components

An approach based on the industrial robots offers new ideas for the manufacture of blade-like complex components. Compared with the multi-axis CNC machine tools, robots are attractive due to their large extendable workspace and competitive price that makes them a cost-effective solution for machining of complex components, especially for large dimension parts. Particularly equipped with the powerful sensing functions, such as machine vision, force-sensing, the robotic machining operations can optimize the running parameters in real-time based on the process knowledge model and multi-sensor feedback information. In this presentation, the focus is visually-guided robotic machining of complex components. Specially, the previous investigation on robotic belt grinding of turbine blade from the perspective of measurement is analyzed and discussed.
