A system includes a machine tool having a clamp. The system also includes a processing head configured to be temporarily held by the clamp of the machine tool. The processing head is also configured to deposit one or more media onto a workpiece. The processing head includes a guide configured to direct energy from an energy source onto the workpiece and/or the one or more media. The processing head also includes one or more supplies including one or more reservoirs within the processing head. The one or more reservoirs are configured to receive the one or more media, store the one or more media as the processing head is moved from one location to another location, and provide the one or more media.

A method and rivet apparatus comprise a rivet block, the rivet block comprising a rivet block, a pin bore, and a rivet feed bore. The rivet block is comprised of a top end and a bottom end. The pin bore includes a top end and a bottom end and is disposed within the rivet block. The pin bore extends from the top end to the bottom end of the rivet block and guides a rivet pin that slides downward within the pin bore to push a head of a rivet into a workpiece. The rivet feed bore includes a top end and a bottom end and is disposed within the rivet block. The rivet feed bore extends from the top end to the bottom end of the rivet block, accepts the rivet at the top end of the rivet feed bore, and guides the rivet to the bottom end of the rivet feed bore. The rivet feed bore intersecting the pin bore between the top end and the bottom end of the pin bore at an oblique angle.
