Keeping in mind that we dont want to push the bit any faster than roughly 200ipm, if we wanted to use a 1/2 inch 4 flute bit, we could solve for spindle speed rather than feed rate. I have a Whiteside 6210 1" carbide tipped Spoilboard Surfacing router bit. Use your ears too, the tool should sound good when cutting trust your gut. Therefore if chip load remains the same, and feed rate increases, either the RPM and or number of cutting edges must increase to maintain the recommended chip load.When calculating the feed rate for any material the chip load is therefore one of the most important factors to be taken into account because the chip load determines the amount of material that each tooth will remove, plus the load that each tooth will have to take. Smaller chips are easier on your machine and tools but can cause too much heat. Was thinking of time saving. Now we can calculate the rim speedor the speed at any point along the outside edge of the cutting router bitusing the following equation: Rim Speed = circumference x router speed (RPM). or is there some safe limit? I also believe you may be pushing the bit as your feed rates are low. Also the milling motor you use is not made for this, neither for such large diameter bits, nor for stationary use in a cnc machine. The same applies to chip load if the recommended chip load is 0.1 mm/tooth the RPM, feed or number of cutting edges may go up or down to maintain the required chip load. That same router, however, drives a 3-inch bit at 178.5 mph at the cutting edge. If an extra long router bit is being used, the chip load should be decreased. %PDF-1.4 % However, suffice it to say its an unsafe speedfor both the wood and the useron the larger bit.
