Radius/Diameter Display
Drawings for lathe parts usually give diameter values. POSITIP 880
can display either the radius or the diameter for you. When the
diameter is being displayed, the diameter symbol (Ø) is shown next to
the position value. See Fig. I.78.
Example: Radius display, position 1 X = 20 mm
Diameter display, position 1 X = 40

Oversizes
Oversizes are entered in the JOB SETUP menu. Oversizes are
automatically taken into account in the DISTANCE-TO-GO mode. When
the displayed distance-to-go is 0, only the oversize amount remains.
When you have set the OVERSIZE field to ON, a symbol for oversize
appears on the right side of the axis bar. See Fig. I.79.
