A client in the aerospace industry approached Birken Manufacturing to CNC machine titanium shroud sets for aircraft engines. Used in a military application, each shroud set is comprised of 12 shroud segments per engine set. Using a Fadal machining center, we CNC milled holes, pockets, radii and slots in the titanium alloy (AMS 4976) material. The serial number was etched on the component by dot peen matrix marking. Deburring was performed to remove any unwanted material. We assembled the parts with precision shoulder screws. We also performed wire electrical discharge machining (EDM) and general turning. Based on customer provided CAD drawings, the shroud set had a length of 8.852", width of 1.149", and thickness of .549". Striving for precision and high quality, we maintained a tight tolerance of +.002"/-.000", a true position of .004" and concentricity of .020". Prior to delivering the shroud sets to the client in Connecticut, we performed dimensional inspection (CMM) and florescent penetrant inspection (FPI).
