2. Milling (machining) - Wikipedia

   en.wikipedia.org/wiki/Milling_(machining)

   The milling machine built by James Nasmyth between 1829 and 1831 for milling the six sides of a hex nut using an indexing fixture. It is clear that milling machines as a distinct class of machine tool (separate from lathes running rotary files) first appeared between 1814 and 1818.

3. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   In drilling and milling, the outside diameter of the tool is the widely agreed surface. In turning and boring, the surface can be defined on either side of the depth of cut, that is, either the starting surface or the ending surface, with neither definition being "wrong" as long as the people involved understand the difference.

4. Lathe - Wikipedia

   en.wikipedia.org/wiki/Lathe

   Modern metal lathe A watchmaker using a lathe to prepare a component cut from copper for a watch. A lathe (/ l eɪ ð /) is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about ...

5. 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.

6. Machine tool - Wikipedia

   Important early machine tools included the slide rest lathe, screw-cutting lathe, turret lathe, milling machine, pattern tracing lathe, shaper, and metal planer, which were all in use before 1840. [12] With these machine tools the decades-old objective of producing interchangeable parts was finally realized. An important early example of ...

7. Machinist - Wikipedia

   Cutting tools: Cutting tools include various milling cutters such as face mills, shell mills, endmills, and form cutters; various drills, reamers, taps, countersinks, counterbores, and core drills; various turning tools, form tools, and threading tools; various grinding wheels [5] distinguished by their geometry, bond, grit size, and compound.

8. Numerical control - Wikipedia

   en.wikipedia.org/wiki/Numerical_control

   Functions include: face milling, shoulder milling, tapping, drilling and some even offer turning. Today, CNC mills can have 3 to 6 axes. Most CNC mills require placing the workpiece on or in them and must be at least as big as the workpiece, but new 3-axis machines are being produced that are much smaller. Lathe: Cuts workpieces while they are ...

9. Spindle (tool) - Wikipedia

   en.wikipedia.org/wiki/Spindle_(tool)

   A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to "the spindle" without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles.
