What is a term used for an unwanted effect that occurs when the slot cut by a saw blade closes over the blade?

The term for an unwanted effect that occurs when the slot cut by a saw blade closes over the blade is "Pinch Back." This phenomenon happens during cutting operations when the material being cut applies pressure against the sides of the kerf (the slot created by the saw), causing it to pinch or clamp down on the blade. This can lead to increased friction, potentially causing the blade to overheat or bind, which can affect the cutting process and create safety hazards.

Kerf refers to the width of the cut made by the blade but does not specifically address the closing over of the blade during the cutting process. Backlash is a term related to the play or looseness in the mechanical components of a machine, which affects precision rather than describing the interaction between the blade and material. Blade drift pertains to the tendency of the blade to cut at an angle rather than straight, which is a different concept from the effect of material clamping the blade during a cut.
