An end effector for welding composite components includes an end effector housing and a welding member mounted to the end effector housing. The end effector further includes a leading roller mounted to the end effector housing forward of the welding member and at least one follower roller mounted to the end effector housing aft of the welding member. The end effector further includes at least one first cooling air jet positioned to direct a first stream of cooling air toward the at least one follower roller.

End effector, welding system, and method for welding composite components

A material deposition process including in situ sensor analysis of a component in a formation state is provided. The material deposition process is implemented in part by a sensor device of an additive manufacturing machine producing the component. The material deposition process includes sensing, by the sensing device, in situ physical properties of an area of interest of the component during a three-dimensional object production. Compliance to specifications or defects are then detected in the in situ physical properties with respect to pre-specified material requirements. The defects are analyzed to determine corrective actions, and an updated three-dimensional object production, which includes the corrective actions, is implemented to complete the component.

Situ monitoring of stress for additively manufactured components

An additive manufacturing system includes an additive manufacturing (AM) device, a first sensor device, and a compute device. The AM device is configured to form a bulk component in a layer-by-layer manner, by at least iteratively depositing a first layer of raw material onto a working surface in a deposition chamber, consolidating the initial layer into an initial additive portion of the bulk component, then forming subsequent additive portions of the bulk component by depositing and consolidating a subsequent plurality of layers of the raw material onto the first additive portion. The first sensor device is configured to measure an actual composition of at least one first byproduct portion formed upon consolidation of one of the first or subsequent layers of raw material in the deposition chamber. The compute device includes a processor and a memory, and is communicatively coupled to the additive manufacturing device and first sensor device. The additive manufacturing device and compute device provide an in situ sensor analysis of the component while in a formation state during a build process by comparing an actual composition of the at least one first byproduct portion to an expected composition range stored in the memory.

Apparatus and method for controlling tolerance of compositions during additive manufacturing

A robotic deburring process that automatically, accurately, and efficiently removes burrs from a workpiece. The robotic deburring process uses CAM location data to establish deburring trajectory, physics based machining models to predict burr type and size, and force control functions to compensate inaccuracies due of inaccuracies of robots arms.

Automatic process planning for robotic deburring operations

A method of providing additive manufacturing includes the steps of (a) developing a plurality of layers to result in a final shape product, (b) developing a space filling algorithm to develop a path, (c) estimating a temperature at a location along the path in an existing direction of the path, and (d) comparing the estimated temperature to a desired temperature and altering the existing direction of the path should the estimated temperature differ from the desired temperature by a predetermined amount. An additive manufacturing system is also disclosed.
