Boring (manufacturing) in the context of "Staff (building material)"

A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformations. Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the workpiece and provide a guided movement of the parts of the machine. Thus, the relative movement between the workpiece and the cutting tool (which is called the toolpath) is controlled or constrained by the machine to at least some extent, rather than being entirely "offhand" or "freehand". It is a power-driven metal cutting machine which assists in managing the needed relative motion between cutting tool and the job that changes the size and shape of the job material.

The precise definition of the term machine tool varies among users. While all machine tools are "machines that help people to make things", not all factory machines are machine tools.

In machining, facing is the cutting of a flat surface perpendicular to some axis of the workpiece. This can be applied in two different areas:

• Facing on a milling machine (perpendicular to the axis of movement), which involves various milling operations, but primarily face milling.
• Facing on a lathe (perpendicular to the axis of rotation), which is commonly used in turning and boring operations.

Other operations remove material in ways similar to facing, for example, planing, shaping, and grinding, but these processes are not labeled by the term "facing."

Turning is a machining process in which a cutting tool is held nearly stationary to cut a rotating workpiece. The cutting tool can be slowly moved back-and-forth, and in-and-out to cut cylindrical shapes, and flat surfaces on the workpiece. Turning is usually done with a lathe.

Usually the term "turning" is used for cutting external surfaces, and "boring" for internal surfaces, or holes. Thus the phrase "turning and boring" categorizes the larger family of processes known as lathing. Additionally, "facing" is cutting the ends of the workpiece, to create flat faces.

In machining, a shaper or shaping machine is a type of machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to machine a linear toolpath. Its cut is analogous to that of a lathe, except that it is (archetypally) linear instead of rotary.

A wood shaper is a functionally different woodworking tool, typically with a powered rotating cutting head and manually fed workpiece, usually known simply as a shaper in North America and spindle moulder in the UK.

A boring bar is a tool used in metalworking and woodworking. Boring is a technique used in many aspects of building. Woodworkers have used boring as a form of drilling for centuries. In woodworking, the boring tool is static in size and used to form circular plunge cuts. In metalworking, boring is slightly different in that the hole that results need not be circular. In metal boring the tool can be plunged and dragged on the X or Y axes to create a slot or asymmetrical hole or channel, or it may be moved only in an up-and-down motion (on the Z axis) to create a perfect circular hole.
