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. Since this speed is only attainable with high speed air spindles the full SFM of 1 000 may not be achievable.
