#### Update Two Axes (Outside Corner)

The Update Two Axes (Outside Corner) soft key can be used to measure an outside corner on a part and then use its corner coordinates to update a specified work offset.

1. Select the Work offset soft key on the second page of the main screen.

2. Select the Update Two Axes (Outside Corner) soft key. The Update Two Axes (Outside Corner) screen appears.

Parameters Definition:

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

- Measured - Specifies the location of the Work Offset. The value is learned from a circle (bore) learn process.

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

- 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.

- Hit Clearance Plane - Selecting this option causes the probe to move to a clearance plane between each hit of the feature. The edit box to the right will allow the user to enter the distance to the plane. This plane is not the program clearance plane.

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.

Follow the on-screen instructions to measure an outside corner, select the work offset to update, and then touch OK to update the work offset.

Update Process:

1. Position the probe next to a surface comprising the corner, and then press the Read Position soft key.

2. Position the probe next to the first point of the same face, and then press the Read Position soft key.

3. Position the probe next to a second surface comprising the corner, and then press the Read Position soft key.

4. Position the probe next to the first point on this second surface, and then press the Read Position soft key.

5. Select Execute. NC Gage automatically takes hits in a similar fashion as depicted below.

The image on the left indicates the manual jog positions (A-E) to which you should jog the probe. The image on the right indicates the automatic probing pathways (red lines) taken by NC Gage as it measures five points at positions 1-4.

8. Once probing has completed, the measured values are updated with the corner's location.

9. Select Work Offset name from the list.

10. Press Confirm to update the work offset. The work offset values will be updated.

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

8. Read position of probe next to first point of first side of corner. All measurements will be taken at level of this point.

9. Read position of probe next to second point of first side of corner.

10. Read position of probe next to first point of second side of corner.

11. Read position of probe next to second point of second side of corner.

12. Determine first and second direction vectors and normal vectors.

13. Compensate points.

14. Determine approximate corner point.

15. Check position of probe, if it is not clear of the corner, move probe to the intersection of the two lines formed by the four learn points. Do this move as a two axis move. If position is above the measurement height move XY first then Z, if the position is below the measurement height move up in Z then move ZY.

16. Position probe to first read point position.

17. Measure toward first side surface, depth matches first point of second side.

18. Position probe approximately to second read point.

19. Measure toward first side surface, depth matches first point of second side.

20. Move to point beyond corner to avoid collision.

21. Position probe approximately to third read point.

22. Measure toward second side surface, depth matches first point of first side.

23. Position probe approximately to fourth read point.

24. Measure toward second side surface, depth matches first point of first side.
