2. Boring bar - Wikipedia

   en.wikipedia.org/wiki/Boring_bar

   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 ...

3. Boring (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Boring_(manufacturing)

   Boring is one of the most basic lathe operations next to turning and drilling. Lathe boring usually requires that the workpiece be held in the chuck and rotated. As the workpiece is rotated, a boring bar with an insert attached to the tip of the bar is fed into an existing hole. When the cutting tool engages the workpiece, a chip is formed.

4. Shaper - Wikipedia

   Shaper tool slide, clapper box and cutting tool Shaper with boring bar setup to allow cutting of internal features, such as keyways, or even shapes that might otherwise be cut with wire EDM. In machining, a shaper is a type of machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to machine a linear ...

   The closer on a manual lathe is either lever-style or handwheel-style. The closer on a CNC lathe is powered (electric, hydraulic, or pneumatic), and it may be controlled by various means: a foot pedal that the operator steps on when desired; a line in the program (for opening and closing under program control); or a button on the control panel.

7. Machining - Wikipedia

   en.wikipedia.org/wiki/Machining

   Lathes are the principal machine tool used in turning. Boring involves the machining of an internal surface of a hole to increase it diameter, this can be performed by either turning the workpiece on a lathe (also called internal turning), or a mill where a tool is rotated around the circumference of the hole.
