Presets
The Preset function is used to indicate the nominal (target) position for
the next move. Once the new nominal position information is entered,
the display will switch to Distance-To-Go mode. It will show the
distance between the current position and the nominal position. Now
the table only needs to move until the display is zero, and will be at the
required nominal position. The information for the location of the
nominal position can be entered as an absolute move from the current
datum zero or as an incremental move from the current
nominal position.
Presetting will also allow which side of the tool will be doing the
machining at the nominal position. The R+/- soft key in the Preset
form defines the offset that will be in effect during the move.
R+
indicates that the center line of the current tool is in a more positive
direction than the edge of the tool.
R- indicates that the center line is
in a more negative direction than the edge of the current tool. Using
R+/- offsets automatically adjusts the distance-to-go value to account
for the diameter of the tool.
Absolute Distance Preset
Example: Milling a shoulder by traversing to display value zero using
absolute position.
The coordinates are entered as absolute dimensions; the datum is the
workpiece zero.

Corner 2: X = 1.50 / Y = 1

Corner 3: X = 1.50 / Y = 2.50

Corner 4: X = 3.00 / Y = 2.50
Press the PRESET soft key, then an axis key to recall the
last entered preset value for that axis.
