This work proposes a process for automating three operations in wind blade manufacturing: trimming to remove flashing left over after bonding two blade skins together, grinding to produce a desired leading-edge shape, and sanding to prepare the blade for bonding. . This work proposes a process for automating three operations in wind blade manufacturing: trimming to remove flashing left over after bonding two blade skins together, grinding to produce a desired leading-edge shape, and sanding to prepare the blade for bonding. . NREL advances the science and engineering of energy efficiency, sustainable transportation, and renewable power technologies and provides the knowledge to integrate and optimize energy systems. The clamshell mold is closed with the shear web inside, and then all components are bonded together. . Wind turbine blades can take a beating, operating 24/7 in the harshest of environments. If blades are damaged the repair process can be costly, tedious, and even dangerous for the technicians involved. The swept area A,directly proportional to the square of the blade length,shows. . Robots can safely trim, grind and sand wind turbine blades. ARVADA, CO —Engineers at the U.
