Oct 02 2017 · 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.

Cutting speed. Cutting speed may be defined as the rate at the workpiece surface irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece such as in a turning operation or the speed of the cutter moving past a workpiece such as in a milling operation.

When milling or drilling or creating a tool path for a CNC machine the feed rate must be determined. Materials have rated surface speeds for a given type of cutter. The harder the material the slower the speed. Given the diameter of the tool and the surface speed the RPMs of the spindle can be calculated.
