The spindle speed N_mathrm {s} N s, in rpm, for a machined operating at cutting speed V, in m/min, is given by the spindle speed formula: N_mathrm {s} = frac {1000 V} {pi D} N s = πD1000V. where D is the diameter of the workpiece in mm. The above equation is used to calculate spindle speed for milling or other material removal processes.

Feed is generally measured in Inches Per Minute (IPM) and speed is measured in Surface Feet per Minute (SFM). A feed of 10 IPM would drive a tool 10 inches in one minute. If you took an end mill and rolled it along the floor like a tire at 100 SFM it would travel 100 feet in one minute.

The cutting speed in CNC machining is also referred to as the surface speed. By definition, it is the relative velocity of the cutting tool against the surface of the material being fed. In simpler terms, it describes how fast the cutting tool moves along the workpiece surface. It is expressed as distance travel per unit of time.

A CNC mill calculates speeds and feeds or SFM based on the information the user enters. The type of CNC mill, the type of machine controller, and the age of the machine will affect the amount of information that can be input directly into the machine. Historically Gcode was created externally from a CNC machine and then loaded onto the machine.

Remember, runout (mentioned above) and deflection are additive. Now, a typical 1/8″ carbide endmill might have a total chipload allowance of ″a thousandth of an inch. According to the chart, if the sum of runout and chipload is just ″, or 5 ten thousandths of an inch, we can reduce tool life by up to 40%.
