Abstract
Using diamond CNC machining equipment, surface roughness specimens have been produced in moderate volume, which have a sinusoidal wave form. Arithmetic average (Ra) values of 0.3, 1.0, and 3.0 micrometers have been produced and delivered under contract to the National Bureau of Standards. The spatial wavelength for all was 100 micrometers. The sinusoidal wave form was diamond machined into the thickness of a .006 inch thick electroless nickel plating on a tool steel substrate. Any combination of Ra and wavelength is possible within the constraints of nickel plate thickness and trough radius. A major consideration was the diamond tool radius, its accuracy, and its effect on the turned profile.
