The structure has at least one shaft that includes a first shaft that extends from the base to a first terminal end that provides a first working surface that is configured to selectively engage a workpiece. The first shaft is integrally formed with the base from the multiple layers to provide an unbroken, monolithic construction.

Abstract: A system includes a first fixture to support one side of a part and a robot that has a second fixture to support an opposite side of the part with respect to the one side. One of the part sides has a target on a surface that indicates a location for the operation. The system has a sensor to measure the target in 3-dimensional space. A tool performs the operation at the location, and a controller moves the robot to pick up the part from the first fixture using the second fixture. The controller presents the target to the sensor for measuring the x,y,z coordinates and the yaw, pitch and roll of the target. The controller moves the second fixture with the part to the tool based upon the measurement.

Abstract: A system for coating ceramic fibers for use in manufacturing a ceramic matric composite (CMC) article includes a frame having a plurality of frame members arranged so as to create a void therebetween. At least one of frame members includes a hollow body and at least one perforated hole defined in the hollow body. Thus, the ceramic fibers are securable at respective ends of the frame and extend across the void. The frame also includes an inlet in fluid communication with the perforated hole(s) so as to allow a coating material to flow into and through the hollow body and out of the perforated hole(s) at a location of at least a portion of one of the ceramic fibers. As such, the coating material is configured to cause the portion of one of the ceramic fibers to separate from the frame such that the portion is uniformly coated with the coating material.
