The finish of the material is dependent upon the feed and speed of the machine. No matter how good the quality of the cutting tool, if you are using the incorrect speed and feed, then the cutting tool will fail. Signs of incorrect feed and speed rates include burning and high heat, causing the knives to dull quickly.

Calculate the feed and speed using this industry standard formula: (RPM x No. Knives)/(FPM x 12) = Knife Marks Per Inch. The cutting angle for different species is listed below.
