摘要： Systems and methods are provided for facilitating pick and placement of preforms. One aspect is a method for picking and placing a preform. The method includes placing an inner surface of a first caul plate into contact with a first side of a stringer preform, such that an outer surface of the first caul plate forms a first plane that is uniform along a length of the stringer preform, placing an inner surface of a second caul plate into contact with a second side of the stringer preform, such that an outer surface of the second caul plate forms a second plane that is parallel to the first plane along a length of the stringer preform, grasping the caul plates at the first plane and the second plane along the length of the stringer preform, and lifting the stringer preform together with the caul plates while maintaining the grasp.

摘要： An ultrasonic cutting blade includes a first end, a second end, and a curved body. The curved body extends between the first end and the second end. The curved body includes a first edge that is configured to contact a workpiece for performing a cutting operation on the workpiece. The curved body includes a radius of curvature that varies between a minimum radius of curvature and a maximum radius of curvature.
