I was in the shop the other day cutting holes out of a 20inx20inx.25in piece of plywood and I noticed that the hole saw was slipping on the board (meaning that it would begin to make an unpleasant sound as the saw hit the board). I had the board clamped down and I realized that a large portion of the board was hanging of the edge. Even if the board was perfectly centered for a cut through the middle of the board (discouraged in the shop, it wastes a large amount of resources), there was too much torque on the board (it would have to be cut).
Assuming that the board wasn't clamped down, I'm wondering what the rotational inertia would be on such a piece of plywood if I was using a hole saw. I know that it would depend on the size of the hole i was cutting, the rpm of the saw, the size of the board, and the location of the cut. I'm just wondering HOW they would relate.
Use any other necessary units (mass etc.)
Is it even possible to create an equation for this?
