OffsetTable and Setup

The measure feature offers an easier method of establishing tool offsets.
The control, not the operator, computes the tool length and wear offsets,
and enters these values into the tool offset tables. The measure feature is
used to measure tool length offset values for the wear or geometry tables; it
should not be used to modify tool diameter offsets.
To enter tool offsets using measure, follow these steps:
1. Establish a fixed machine position without a tool in the tool holder.
This position can be any fixed, nonmovable location on the machine
that the tool can be jogged against consistently using a variety of
different tools.
If you enter: Then:
a tool length inthe
geometry offset table
jog the machine gauge line(on theaxis being updated) to this
position. The valueof this position, located in the work
coordinate system, must be recorded. The user keysin this
value in steps 6and 7. No tool offsets shouldbe activeand no
tool shouldbe inthe toolholder.
a tool length wearin the
wear offset table,
jog the machine gauge lineto thefixed position. Add the
original toollength offset from thetool geometry tableto the
fixed machine location. The user keysin thisvalue instep 7.
No tool offsetsshould beactive andno toolshould be in the
tool holder. The value of this position, locatedin thework
coordinate system, must be recorded.
2. Access the tool geometry or wear offset table.
3. Cursor down to the offset that you want to change. The offset can be
displayed in either inch or metric measurements.
4. Load the tool that you want to measure into the tool holder.
5. Using incremental, continuous or handwheel mode, jog the tool tip to
the fixed location determined in step 1.
6. Press the {MEASURE} softkey.
7. Key in the coordinate value of the fixed location determined in step 1.
8. Press the [ENTER] key.
The control now subtracts the keyed in position from the current tool
position and enters this difference as the offset value into the table.
