LA LA LA LA LATHE THE THE THE THE
A Lathe is defined as a machine tool for the removal of material from a workpiece by grip-
ping it securely in a holding device and rotating it under power against a suitable cutting
tool. On lathes the tool moves along a rotating workpiece. The carriage or Z-axis moves the
tool toward the spindle. The cross slide or X-axis, mounted on the carriage, moves the turret
that holds the tool toward and away from the spindle. The origin of the coordinate system is
the center of the spindle. Okuma lathes can be Flat bed or Slant bed type lathes. The slant
bed allows the chips to fall into the chip pan rather than on tools or slideways. Figure 3-1
shows the axis nomenclature for an Okuma lathe.
