Mechanical Separating

Mechanical separating processes use mechanical force and a cutting tool or edge to remove material from a workpiece or divide it into separate pieces. These processes include machining operations such as turning, milling, drilling, grinding, and sawing, as well as shearing, punching, and knife-cutting processes such as slicing and slitting.

The mechanisms by which separation occurs vary considerably. Machining generally removes material in the form of chips or small particles to produce a desired shape, dimension, or surface. Shearing and punching separate material through highly localized deformation and fracture between opposing cutting edges. Knife cutting uses a sharpened edge to penetrate and separate material and may involve either direct push cutting or a slicing action in which the edge also moves along the material.

Although all of these processes rely on mechanical forces, the way the material deforms and ultimately separates can be quite different. Understanding these different mechanisms helps explain why particular cutting processes, tools, and machines are better suited to different materials and manufacturing applications.
