Machine tool that rotates a circular tool with numerous cutting edges arranged symmetrically about its axis, called a milling cutter. The metal workpiece is usually held in a vise clamped to a table that can move in three perpendicular directions. Cutters of many shapes and sizes are available for a wide variety of milling operations. Milling machines cut flat surfaces, grooves, shoulders, inclined surfaces, dovetails, and T-slots. Various form-tooth cutters are used for cutting concave forms and convex grooves, for rounding corners, and for cutting gear teeth.

Process that mats together fleece (raw wool) by subjecting it to moisture, heat, friction, and pressure. Sheep hair have scales that open somewhat when wet; layering hairs in a parallel fashion and applying some form of agitation cause the hairs to tighten together in a solid mat. The result is a lightweight, windproof, and water-resistant fabric that has been used for millennia to make hats, boots, and tents. Light felting is sometimes done to woven or knitted wool, a process known as fulling, to create a thicker and softer fabric.
