Jan 01, 2001· Acoustic emission (AE) is generally understood as the release of a vibrational wave emitted by a material reacting to applied stress. The acoustic emission generated during grinding and machining processes has been proved to be related to the process state and to the surface condition of the tool and workpiece, .


Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle ), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.).
