Abstract: An apparatus and method to machine cavities in die blanks having little to no taper. The apparatus includes an electrode tool (200) including intersecting walls coated with electrically insulating coating (258), an erosion face (204) comprising a cross section of the walls exposed through the electrically insulating coating, and a channel formed by the walls to supply electrolyte to the erosion face, the channels defined by interior surfaces of the walls and having an opening formed by edges of the erosion face. The method includes pulsed electrochemical machining a work piece with the electrode tool.

Abstract: Extrusion dies and methods of manufacturing extrusions dies, the extrusion die including a first plate and a second plate. The first plate has first upstream and downstream surfaces. A first material of the first plate has a first elastic modulus. The first plate includes pins formed between a plurality of slots. The pins and slots define a discharge face for the extrusion die at the first downstream surface of the first plate. The second plate has second upstream and downstream surfaces. The second plate is joined at the second downstream surface to the first upstream surface of the first plate. A second material of the second plate has a second elastic modulus. The second elastic modulus is greater than the first elastic modulus. A plurality of feed holes extend from the second upstream surface of the second plate through the extrusion die into communication with the slots.

Abstract: A method and extrusion die to form a laminar integral skin of a honeycomb structure is provided. The method includes extruding a ceramic precursor batch through a die with feedholes in entry side and slots in exit face of the die to form the honeycomb structure. In a region on the periphery of the die configured to form the cell matrix, a series of concentric slots around the matrix in the exit face of the die are configured to feed skin onto the matrix. Ring sections between concentric slots are angled away from the center and a mask is disposed on top of the periphery producing a channel for extruded skin to meet and bond to extruded matrix. Optionally, slots in the skin-forming ring sections enhance knitting between laminar skin layers.
