Introduction The geometry of a workpiece is described by a rectangular or Cartesian coordinate system named in honor of the French mathematician and philosopher Ren Descartes In Latin Renatus Cartesius 1596 to 1650 The Cartesian coordinate system con sists of three mutually perpendicular axes X Y and Z The point of intersection of these axes Is called the datum or origin of the co ordinate system Fig 1 The Cartesian coordinate system To determine positions on a workpiece the coordinate system Is laid onto the workpiece With lathe work i e rotationally sym metrical workpieces the Z axis move along the axis of rotation while the X axis moves in the direction of the radius or diameter The Y axis can be disregarded since it would always have the same values as the X axis Fig 2 The Cartesian coordinate system with lathe work POSITIP 855 Operating Instructions 7 1 Fundamentals of Positioning Cross slide saddle and top slide On conventional lathes the tool is mounted on a slide that moves in the direction of the X axis the cross slide and in the direction of the Z axis the saddle Most lathes have a top slide above the saddle The top slide moves In Z axis direction and is designated Z Fig 3 Axes of movement on a lathe Datum setting The workpiece drawing normally specifies the workpiece face as the absolute datum and indicates the axis of rotation The datum setti
