Abstract
An improved method of machines grooves forming Pearson notches in a pattern on hollow shell casings for munitions for at least one of increased functionality and/or performance. Rather than running a broach through a hollow casing, a CNC lathe with a multi-axis tool with cutting implement can precisely locate and form grooves along either an interior or an exterior surface of a hollow shell casing.
