33. Equation (8) relates the defect volume of triangular fly-cut grooves, Vd, to 12×L×W×4 Ra.
34. We observe that analysis of the surface with optical profilometry showed the most common groove frequency for the 16 μin surface finish was a factor of ≈1.4 higher than the 32 μin surface finish. The correlation of increased groove frequency with an decrease in ejecta production over the pressures spanned is interesting and warrants further investigation.
