Once up a time, I was told that cutting on a circular saw (specifically a table saw) should be done withe the speed at between 10, 000 to 18, 000 surface feet per minute (sfpm). I thought these were important numbers for blade life and quality of cut... until I figured out that some smaller saws are slower that that new. (Ask me if you want those and I'll post.)
Here is an online calculator to find and work with various data for circular saw blades: Circular Saw Feeds & Speeds Calculator
Then I found a few more: Circular Saw Calculator, Quad Sawbox, Twin, Feed Speed, Horsepower, Tooth Bite, Gullet Fill, Sawmill - Online Expos Circular Saw Horsepower Calculator!
Note-- please realize that the blade motor RPM, is not the arbor RPM... unless the pulleys between them are the saem size, 1:1. Usually, they are different in size.
Actually, I found these while looking for something to figure out the feed rate of... which should use the rpm, diameter, teeth per, gullet area... which then would affect depth of cut... and feed rate. Still looking for those formulas, which should be available for CNC TS'es...Rip, Edger and Gang saws. What I've found so far on that is something like this:
The feed speed V, [m/min] is the speed of the forward feed movement of the workpiece or of the tool. The feed speed is proportional to the feed per tooth fz and is essentially responsible for the quantitative output. It is calculated by the formula: Vf = fz × n × z/1000 [m/min]
Vf = Feed speed [m/min]
fz = Feed per tooth [mm]
n = Revolutions per minute [min 1]
z = Number of cutting edges/teeth
When machining solid wood feed speeds range from 1 – 220 m/min (3.3 - 723 ft/min) with a highest frequency of occurrence in the range 5 – 25 m/min. (16 - 82 ft/min.) High feed speeds require large technical expenditure on tool construction, machine design, workpiece guidance, power demand etc... But there's another one out there that takes into consideration how much waste the gullet has to carry away and the chip load of the teeth on various density materials...
