Imagine the cutting tool as a rolling ring or cylinder. The distance traveled in one revolution times rpm is its surface speed. If the circle above had a diameter of 3.82", the circumference would be 12". As a result, every revolution would produce a linear distance of 1', and a spindle speed of 100 rpm would be a cutting speed of 100 sfm.
The "speeds" part of the speeds and feeds calculator is the rotation speed of either the tool (e.g., for drilling) or the workpiece (e.g., for turning on a lathe). For a given tool and workpiece material, there is a range of recommended cutting or surface speeds between the two materials. Given the surface speed, you can calculate the spindle …

The figures obtained from the calculation are for reference only. The conditions for machining depend on the machine tool you are using. ... Face mill diameter (D1) = 220 mm In this case, the table feed per minute (vf) and the total table feed length (L) are: vf = 0.35 × 12 × 200 = 840 mm/min L = 350 + 220 = 570 mm Substitute these values ...
What is Chip Load? Meaning #1 – How Chip load is used in milling catalogs, and by most machinists. The maximum load that the cutting edge of a specific milling cutter (or indexable insert) can withstand without yielding or having a very short tool-life.. The chip load is specified in mm/tooth or Inch per tooth (IPT) units.
Feed (mm per revolution) = Feed Per Tooth x Number of Teeth; Revolutions Per Minute = 1,000 x Cutting Speed / π x Diameter of Rod (mm) Here, accuracy is key to obtain the best machining time estimate.
