V0612 - 20i-T / 30i-T - Installation/Operation - DRO operation - (7/32)
2.2.1 Example
Using the lower figure, let us imagine we wish to make a part in which three
holes have to be drilled with the coordinates stated. It is clear that the
blueprint will only reflect the incremental coordinates (I) or the absolute ones
(ABS) referring to the part zero (point "0" in the figure) although the DRO also
shows them with respect to home (Io).
After referencing the axes, as was described in the previous section, we can
make this part in incremental or absolute mode according to whether we
chose a type of dimensions (I) or (ABS) of the blue-print.
In incremental
mode:
-Press this key until the ABS LED is turned off.
-Move the axis up to the face of the part to set it as part zero.
At this point, one can proceed in two ways:
-Preset the axis with a zero value by pressing this keystroke sequence:
-Move the axis towards the first position until the DRO reads: 22.600.
or...
-Preset the axis with a value of 22.600 by pressing this keystroke sequence.
In case of a mistake, press this key to cancel it and leave it as it was.
Pressing this key displays the previous preset value.
- Move the axis towards the first position until the DRO reads: 0.000.
This last method turns out to be more practical as after selecting the
destination coordinate one only has to remember to move the axis until the
DRO reads zero.
