The milling machine uses a multi-toothed cutter to remove metal from moving stock. There is also a quill feed lever on the mill head to feed the spindle up and down. The bed can also be manually fed in the X, Y, and Z axes. Best practices are to adjust the Z axis first, then Y, then X. When an axis is properly positioned and is no longer to be

On the other hand, the CNC machine is programmed with the RPM (Spindle speed). Therefore it is common that we need to compute the RPM from a given SFM either for programming or to ensure that the SFM we want to run at is within the machine's limit. It is calculated by dividing the cutting speed by the cutter's circumference.
