What are Speeds and Feeds in CNC Machining? Speeds and feeds refer to different velocities of a cutting process. While cutting speed determines surface feet of material removed per minute (SFM), spindle speed is the rotational speed of the cutting tool/workpiece (RPM), and feed rate is the speed at which the cutting tool advances …

be selected during the set-up of the equipment. Operating parameters such as mill charge, rotation speed, and milling time can be changed and controlled [16–20]. Material that is easy to mill is economically more suitable for the preparation of powder feedstock. Milling is generally analyzed through energy–size relationship models [21].

End Mill Feeds and Speeds. The most important aspect of milling with end mills is to run the tool at the proper RPM (revolutions per minute or spindle speed) and IPM (inches per minute or feed rate). We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.
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 …
Find the spindle speed for milling a steel workpiece having a diameter of 20 mm. Take cutting speed V to be 5 m/min. Also, determine the feed rate for a single tooth having feed per tooth of 10 mm. To calculate spindle speed: Enter the diameter of the part, D = 20 mm. Fill in the cutting speed, V = 5 m/min. Using the spindle speed formula:

Cutting speed shows the linear speed of the furthest points of the flutes of your tool. Those are the fastest moving points on your cutting edges. In other words, RPM depends only on your spindle speed while cutting speed depends on your spindle speed and tool diameter. Effects of Feed Rate and Speed
