The cutting processes of ultra fine grain stainless steels are compared to that of normal grain steel in microscale cutting with a single point tool made of single crystal diamond. Cutting force is measured with oscillation in the dynamic component. Vibration in cutting force is reduced with the grain size. Shear angles are measured to discuss the cutting process with changes in depth of cutting. The large shear angle is observed when the grain size becomes small. The surface finish is also improved when the ultra fine grain steel is machined.
