Here's the chart of rotation speeds for circular saw blades, measured in RPM and categorized by the common diameter sizes: As you can see, regular diameters like 7-1/4″ and 8″ are used within the range of 4,000 to 7,000 RPM. Larger saw blade should run at 3,000 RPM or less. Remember: these are approximate values; true specifications are ...

500SFM X 3.82 / .125 = 15,280rpm. This would be in the range of a typical cnc router. The next issue would be the feedrate. Using an RPM of 15,280 would give a feedrate of 122 in/min. This is too fast a feedrate for many hobby machines. So what you can do is use an endmill with only 2 flutes.

If you are trying to figure how fast to set your router - let's aim at the 130 fps. When you simplify the math, divide 30,000 by the diameter of the blade in inches to find the RPM. For approximately 130 linear feet per second: RPM = 30,000/D. 145 linear feet per second: RPM = 33,500/D. 160 linear feet per second: RPM = 37,000/D.

Now choose the right surface feet per minute (SFM) or surface meters per minute (SMM) Use the SFM and the diameter of the mill to calculate the RPM of your machine. Use the RPM, IPT, CLF and the number of flutes to calculate the feed rate or IPM. If you want to be conservative, choose a slightly lower SFM, but always choose the recommended FPT.

For example, the average recommended feed rate for a .50-inch tool is approximately 0.002 inch per tooth. For a .50-inch tool operating at .025-inch width of cut, the feed would need to be programmed at 0.0046 inch per tooth to accommodate for RCT. RCT has a great impact on productivity when such small radial engagements are used.

Cutting speeds and feed rates. My mill, for example, has a continuously variable speed range between 190 and 4000rpm. If I am cutting CZ121 brass, which has a nominal cutting speed of 100M/min, the maximum diameter of cutter I can use at the theoretically correct speed will be. (100 x 1000)/ (3 x 4000) = 8.3mm or a little over 8mm.

In summary, high-feed milling is all about chip thinning. You must increase feed rate to compensate for the chip thinning created by the large lead angle, typically 80° to 82.5°. In most cases your feed rate is four to five times faster than standard feed rates utilizing square shoulder or 45° lead milling cutters.
