10 I

I – 2 Milling Specific Operations

Presets

The Preset function allows the operator 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

and show the distance between the current position and the nominal

position. The operator now only needs to move the table until the

display is zero and he 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 also allows the operator to indicate 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. See Fig. I.13.

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. See Fig. I.14 & Fig. I.15.
