• alloys
  

  alloys

  Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.

• climb milling ( down milling)
  

  climb milling ( down milling)

  Rotation of a milling tool in the same direction as the feed at the point of contact. Chips are cut to maximum thickness at the initial engagement of the cutter’s teeth with the workpiece and decrease in thickness at the end of engagement. See conventional milling.

• feed
  

  feed

  Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

• flutes
  

  flutes

  Grooves and spaces in the body of a tool that permit chip removal from, and cutting-fluid application to, the point of cut.

• gang cutting ( milling)
  

  gang cutting ( milling)

  Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

• milling
  

  milling

  Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

• slotting
  

  slotting

  Machining, normally milling, that creates slots, grooves and similar recesses in workpieces, including T-slots and dovetails.
