ments that must be used when planning coordinate
motions.

Figure 1
controls the motion assignments
for X and Y (depending on which
plane is chosen). As an example,
when a curve is to be generated
in the XZ plane, all motion of X
is dictated by Z. As Z is lowered,
the display for X on the DRO
changes as well.
The user chooses how much
the step rate will be in Z. He is
given the amount that X must
move to be in the right place for
the next cut each time Z moves.
The operator moves the table
until the display reads 0.000 for
X; the cut can then be made. In
this way, no matter how deep Z
is set, as long as X reads 0.000,
the table is in the correct location
in X and Z, to make a cut along
the edge of the curve.
