This creates the optimal speeds and feeds or SFM tailored to the exact part and CNC machine. How do you calculate feed for turning? Turning Feed Rate = Rotational Speed (N) x Feed Rate (fr) Rotational Speed (N) = Cutting Speed (SFM) / π x Original Diameter Feed Rate (fr) = Rotational Speed (N) x Feed (f).

Feed rate is calculated using the following equation: Feed = N x T x Z N = number of cutting edges (flutes) T= chip load (chip per tooth) is the amount of material, which should be removed by each tooth of the cutter as it rotates and advances into the work. (mm per tooth) Z= RPM, the speed at which the cutter revolves in the spindle.

Because only the feed-direction angle is changed, which is a relatively easy adjustment in the milling process, this method efficiently reduces the cutting force in CFRP milling.

In woodworking, the ideal feed rate is one that is slow enough not to bog down the motor, yet fast enough to avoid burning the material. Certain woods, such as black cherry and maple are more prone to burning than others. The right feed rate is usually obtained by feel if the material is hand fed, or by trial and error if a power feeder is used.
