     A Presentation On:
     LATHE TURNING
By: Tyler John Wiegand the 1st
 A dumb fact about the: LATHE

• The lathe is one of the oldest and most
  important of the machine tools.
                 What it does….
• The lathe operates on the principle of the work piece being
  rotated against the edge of a cutting tool.
• The cutting tool can be controlled to move lengthwise and
  across the face of the material being machined (turned).
• It is also possible to bore, ream (finishing a hole to exact
  size), and cut threads and tapers.
          Variations of the Lathe

• Turning Cell: One of the most complex lathes, it is capable of
  automated machining without operator intervention. After the turning
  cell is set up and programmed, it changes parts and tools, monitors tool
  condition, and determines when tools need to be changed. The
  finished machined parts are measured automatically and the data is fed
  back into the machine’s CNC controls, which makes necessary
  adjustments to maintain consistent machining accuracy. Also known
  as an indexed tool lathe.

                        Continued…

• Turret Lathe: Is used when a number of identical
  parts must be turned. It is a conventional lathe fitted with
  a six sided tool holder called a turret. Different cutting
  tools fitted in the turret rotate into position for machining
  operations. Also known as an indexed tool lathe.
          Variations of the Lathe
                  Continued… Again…

• The Engine Lathe: Is the simplest and most common type
  of lathe, in which the work piece is suspended by its ends between the
  headstock and the tailstock. The cutting tool is mounted on the
  carriage that can move back and forth between the headstock and
  tailstock.
                 More Lathe Stuff
• Hand-fed machines:                  Used for machining small work
  pieces at high rates of production. It has mechanical stops that ensure
  there is little chance for dimensional error.

• Power-fed machines:                commonly have either a ram turret
  arrangement, or a saddle mounted turret which moves longitudinally
  along the lathe ways. Have larger work piece capacity than hand-fed
  models.

• Automatic Machines:                  are capable of moving through an
  entire sequence of cutting operations without the intervention of a
  human operator.

• Massed-tool lathe:              cutting is performed by several tools
  positioned in one or more tool blocks.

                             Continued…

• The Guided path, tracer, or duplicating
  lathe: Is designed to reproduce the contour of a template or master
   part on a work piece. The lathe is equipped with a tracer finger or
   stylus that travels along the pattern to be duplicated. The movement of
   the tracer is transmitted, usually by hydraulic linkage, to the controls of
   the lathe to guide the single-point cutting tool along a path that
   precisely matches the pattern

• Computer numerical-control lathe (CNC):                                   Is
   used for repetitive machining of duplicate parts. Requires no pattern
   or template, and controlled electronically by a punch tape or a
   computer program which contains complete instructions for making
   the part.
           In Conclusion…

• Lathes do things
