Cutting grooves requires tremendous precision in pursuit of aerospace-grade tolerances. Typical steps include fly-cutting the face, cutting the grooves and applying some form of surface roughness to the flat part of the face between the grooves. The Advanced Research Team scrutinized each of these elements closely in search of ways to improve them. A great deal of discussion and debate led the group to agree that the process of rendering a groove could be more precise and consistent from one end of the groove to the other, and from one groove to another.
