This document is a technical specification for creating four ultra-fine Electrical Discharge Machining (EDM) notches on a carbon steel plate at the Portsmouth Naval Shipyard. The notches are precisely specified with uniform dimensions: each notch is 0.250" long, 0.006" wide, and 0.040" deep, with tight tolerances of +/- 0.002" for length and -0.002" for depth. The material will be provided by PNS (Portsmouth Naval Shipyard), and all notches are to be disguised with epoxy. The technical drawing includes multiple views showing the approximate locations of the four notches from different angles, with detailed annotations by Scott Webster, an NDT Engineering Technician and Instructor, including contact information for the Portsmouth Naval Shipyard in Kittery, Maine.
