CNC machining is a subtractive manufacturing process that involves shearing away material until the final product is achieved. While cutting speed is more important in optimizing factors like tool life and power consumption, the feed rate is vital in determining the machining time and roughness of the finished area. This article will compare feed rate vs. cutting speed and explain why the difference is important.

Split point and double margin design provide superior hole finish and size control. Straight through drilling without pecking cycle. Increased tool life and chip control in moderate-to-difficult workpiece materials

Two flute design is ideal for softer alloyed, non-ferrous applications that require slotting or involve heavy chip loads. Available in Square, Corner Radius, and Ball Nose

Feed rate is defined as the velocity at which the cutter is advanced against the workpiece. This is measured in either inch per revolution or millimeters per revolution. The feed rate also affects the same factors that the cutting speed influences. The only difference is that its effects are to a lesser extent. However, the feed rate is important in the final aesthetic look of the machined part (i.e., the surface finish of the machined part). Hence, its optimization is also quite important in CNC machining processes.

4-facet point design, stub length, and mirror finish provide the highest quality spot. Available in Ti-NAMITE®-A coatings and uncoated options for a wide range of materials

Three flute design features improved chip space over four flutes and increased strength and feed capability over two flutes. Available in Square, Corner Radius, and Ball Nose

Four flute design allows for higher feed and decreased deflection, improving productivity and surface finish. Available in Square, Corner Radius, and Ball Nose

Cutting speed is generally defined as the relative velocity between the surface of the workpiece and the cutting tool. Machinists measure cutting speed in meters per minute or feet per minute. The cutting speed is quite an important factor in the determination of other parameters of CNC machining, such as cutting temperature, power consumption, tool life, etc. Its influence on these parameters serves as a significant difference between feed rate and cutting speed.

4-facet point design stabilizes on entry for superior hole size control and tool life. Available in Ti-NAMITE®-A coatings and uncoated options for a wide range of materials

Variable helix design improves stability, extends tool life, and improves part quality in challenging applications. 3 Flute Square and Corner Radius configurations available

4-facet point design stabilizes on entry for superior hole size control and tool life (>0.08mm). 2-facet point on 0.08mm and smaller. Mirror finishes improve chip flow as hole depth increases

Due to the similarities both parameters have, it is possible to confuse them with each other. Though, there are quite a few practical factors that serve as the difference between feed rate and cutting speed. Examples of such factors include:

4-facet point geometry provides centering assistance upon entry. Wide diameters offer ability to drill larger than average holes than is commonly possible in micro spindles
