Hello,

I come to you guys because I need help determining what saw blade to use for a project. My kinematics final project is to design a saw mill from the 1800's. We have to complete a cut on a 12" log in a certain amount of time. I'm looking for help on determining rpm of the blade and tpi, or other specifications i might need. I've found a few pdf files on how to calculate pitch but nothing on this. I've looked at specs on band saws and reciprocating saws.

Thanks in advance.

Most circle mill blades are specified to cut 1/10 of an inch per tooth, per revolution. Most mills run a blade at least 44 inches in diameter, and are "hammered" and "set" for a specific RPM, usually pertaining to the horsepower of the mill. There are many, many designs of blades and profiles of teeth, but usually a blade will have one tooth per inch of diameter. My mill has a 52 inch blade with 52 teeth, 8-9 ga - 2-1/2 to be specific. My mill has 125 hp and runs 600 RPM.

Now the cut is purely hypothetical. Most mills will not have the power to cut at that rate, or anything close to it. You might contact www.menomineesaw.com/ and ask the experts for more specifics.
