Abstract: A liquid-jet-guided laser system can be used to generate functional slots having different depth and sidewall profiles by applying active control of laser beam parameters. Blinds slots can be processed onto a workpiece, such as a tire mold or a turbine vane, for an insertion of a sipe or a sealing element, respectively. Through slots can also be processed onto a workpiece, such as a turbine element for cooling during operation or a semiconductor wafer for singulation purpose. The processing of the workpiece can include a two-step procedure, wherein the first step comprises a pre-cut. The pre-cut cuts a contour outline of a slot onto a workpiece corresponding to an element that is to be inserted into the slot. The second step comprises a removal cut to remove excess workpiece material in between the contour outline. The liquid-jet-guided laser system can employ multiple-wavelength processing of a multiple-material workpiece.

Abstract: A portable programmable machine enhances efficiency and ergonomics associated with conducting otherwise manual operations within confined spaces. A main body supports a programmable telescoping arm configured to extend through an access port to reach a confined space. The arm includes an articulating wrist for holding and manipulating tools for autonomously processing work parts. The machine can also act semi-autonomously to accommodate interventions of an operator for overriding and fine-tuning interaction of a tool with a work part for proper processing of the part. The arm communicates with a computer in the main body for processing numerical data, and the operator may use a reference camera to fine tune any particular process. The machine incorporates multiple processing functions, for example collar swaging, nut running, cleaning, and/or application of sealants, all through an aircraft wing access port. The main body has lockable wheels for securing the main body near the access port.
