Spindle Speed Cap . As shown above, the cutter speed (RPM) is defined by the SFM (based on material) and the cutter diameter. With miniature tooling and/or certain materials the speed calculation sometimes yields an unrealistic spindle speed. For example, a .047 cutter in 6061 aluminum (SFM 1,000) would return a speed of ~81,000 RPM.
