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 In a case like this
