Optimal feed rates for CNC machining - WOODWEB

A two-flute ruffing/finisher will provide you with feed speeds 20 to 30 percent less than a ruffer, and has less tool life. A two-flute finishing tool will provide the same feed speeds, but again, less tool life. Let's say you are machining a 3/4-inch-thick hardwood and can achieve feed speeds of …

Technical - Speeds & Feeds

Based on this equation, as RPM increases, feed rate will also increase if all other settings remain the same. If the number of cutting edges changes, however the feed rate will either increase or decrease depending on the whether the number goes up or down. The same applies to chip load if the recommended chip load is 0.1 mm/tooth the RPM, feed ...

Speeds and Feeds - University of Florida

Next, calculate the feed rate used for plunging. Remember annular cutters should be fed at approximately 25% of the feedrate for an equivalent sized endmill. From Table 3, lookup the recommended feed per tooth for a 1″ HSS endmill (f t ≈ 0.008 in/tooth) and calculate the plunge feed rate using Equation 3: f [in/min] = N [rpm] × f r [in/rev]
