Cutting forces for circular tube saws

Cutting forces for circular tube saws

Cutting forces for circular tube saws

(OP)
I am trying to design some clamps for a circular saw tube cutting machine. I need to figure out the cutting forces that are exerted on a circular tube so that I can design the clamps and avoid the tubes from spinning (a common problem in circular tube cutting).

I appreciate your help.

RE: Cutting forces for circular tube saws

I've designed many abrasive cut off saws. The forces exerted are going to depend on a few things:

1) The material being cut.
2) The speed of the cutting blade.
3) The force/pressure of the blade on the tube.
4) The type of blade (abrasive media)
5) Feed rate.

I'm afraid you are going to have to try and measure what you are looking for. Only precision saw manufactures are going to know enough about the saw to give you any useable information.

Best bet is to calculate the maximum force that the tube can handle without distortion, and use that. You can't hold it any tighter anyhow.

Also, the shape of the jaws and the cooeficient of friction are to be considered. Obviously round chucks and ridges perpendicular to the twist.
