    2020-7-7Spindle Speed Cap . As shown above the cutter speed RPM is defined by the SFM based on material and the cutter diameter. With miniature tooling andor certain materials the speed calculation sometimes yields an unrealistic spindle speed. For example a .047 cutter in 6061 aluminum SFM 1000 would return a speed of 81000 RPM.
