#### Update One Axis

The Update One Axis soft key can be used to measure a point on part and then use its coordinates to update a work offset selected in the list.

1. Press the Set Work Offsets soft key from the Main screen. The soft keys at the bottom will change to show the different types of features you can measure to set a work offset.

2. Press the Update One Axis soft key to display the Update One Axis screen.

3. Follow the on-screen instructions then press the Confirm soft key to complete the procedure or press the Return soft key to return to the previous screen without saving.

Parameters Definition:

- Work Offset - Specifies the Work offset which is chosen to be updated.

- Measured X Y or Z - Specifies the location of the Work Offset. The value is learned from a point learn process. The axis will vary based on the direction selected at the bottom left corner of the screen.

- Offset - The work offset will be offset this distance away from the measured point.

- Prehit Distance - Specifies the location that the probe will start searching for the surface. This is the distance away from the surface nominal that the probe will move at the "finding" speed that was established in the setup screen.

Available Navigation Bar Soft Keys on this Screen:

|  |  | Set Work Offsets This soft key displays a new screen with new soft keys for updating work offsets in various situations.
| Select a Work Offset to Update This soft key scrolls through the work offset listing one by one with each press of the soft key. |  |
|  |  | Confirm to Update Work Offset This will be available after the machine has learned the feature location. It will save the command to the program.

Update Process:

1. Position the probe above the point.

2. Press the Read Position soft key . The tip position is read as the bore center and distance away from the surface. Press the Back to Last Step soft key to cancel this position and read a new position.

3. Press the Execute soft key and NC Gage automatically probes a point along the opposite direction of the work face normal. The probe will search a distance of the probe radius plus 3 times the prehit distance.

4. Once probing has completed, the measured values are updated. Select the Work Offset name from the list by pressing the Select a Work Offset to Update soft key until the desired work offset is highlighted. Parameters for each highlighted work offset will be updated on the screen as each one is selected.

5. Press the Confirm soft key to save the work offset value on this axis will be updated. Press the Return soft key to return to the previous screen without saving.

The following is the specific feature path and logic built into NC Gage:

- Read position of probe above surface.

- Measure Surface with search distance of probe radius + 3* prehit distance

- Return to read position point.
