9. XY Table
In addition to movements caused by the servo motors in the X and Y axes, the
XY table also moves vertically (via the Z axis motor) to adjust itself to the
height of the part being placed. The X and Y motors can move in increments of
0.01 mm. The Z motor moves in increments of 0.002 mm. The D axis moves in
increments of 0.0053 mm.

Chapter 9 XY Table
As shown in the configuration of the automatic table height changer
(figure 9-2), the Z axis motor rotates to move the rack and pinion system,
moving the LM guides left and right. On the LM guides there are four fixed Z
cams. As the LM guides move, the cam followers slide over the Z cam and this
makes the back-up plate move up and down.
