E-2 SETTING OF COORDINATE SYSTEM
Coordinate system plus/minus sign:
<X-axis>
For the X-axis reversed JIS specification machine,
the positive and negative directions of the X-axis
are the reverse of those of conventional
specification machines.
<Z-axis>
Set the edge position of the cutting tool mounted in the
turret in these coordinate systems in the NC.
Because a diametral command is used for the X-
axis, the value to be set is twice the actual
distance.
Positive (+)
Direction in which workpiece
diameter increases
Negative (
)
Direction in which workpiece
diameter decreases
Positive (+)
The direction in which the turret
moves away from the workpiece
Negative (
)
The direction in which the turret
moves closer to the workpiece
