#### 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. From the main screen, choose the Set Work Offsets soft key. The soft keys at the bottom will change to show the different types of features you can measure to set a work offset:

2. Select the Update One Axis soft key. The Update One Axis screen appears.

3. Follow the on-screen instructions to measure a point, select the work offset to update, and then touch OK to update that work offset.

Parameters Definition:

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

- 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:

| Backward When enabled, this soft key scrolls back to any additional buttons available on the first page for this screen. |  | Back to Last Step This soft key goes back a step in the current procedure.
| Read Probe Position and Continue with Next Step This soft key reads the current probe position and then advances to the next step in the procedure. |  | Select Measurement Face This soft key determines the direction of probing and the location of the clearance moves for the feature. You can press this multiple times to choose a different measurement face. Available faces are: X+, X-, Y+, Y-, Z+ and Z-.
| Work Offset This soft key selects the named work offset from the list of offsets. Pressing this again will select the next work offset from the list. |  | Execute This soft key causes the machine to measure the feature. It will only be available after all the necessary probe positions to identify the feature location have been learned (or typed in). It lets you make changes and test run the feature before committing the feature to the program.
| Cancel All Steps / Abort This soft key stops and resets the current operation. If learning a feature, it removes all the learned probe positions. |  | Select a Probe If the Select Probe screen isn't the current screen then this soft key accesses the Select Probe screen. If the Select Probe screen is already visible then this soft key selects scrolls through each probe in the Probe list with each touch of the soft key.
| Help This soft key accesses the NC Gage help file. |  | Return This soft key returns the view up one level to the previous screen.
| 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. |  | Forward When enabled, this soft key scrolls forward to any additional soft keys available on the second page for this screen.

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 to cancel this position if you want to read a new one.

3. Select Execute. NC Gage automatically probes a point along the opposite direction of 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.

5. Select the desired Work Offset name from the list.

6. Touch the OK soft key. The work offset value on this axis will be updated.

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.
