### Point

To create a Point command:

1. Select the Measure soft key from the main screen's Navigation Bar.

2. Select the Point soft key from the Navigation Bar. The Measure Point screen appears.

3. Follow the instructions on the screen to insert the command. Pay attention to the graphical description in the upper left section of the screen. It will show you where to position the probe for measurements and changes when multiple steps are required.

Parameters Definition:

- Center (XYZ Nominal) - Defines the nominal position of the top surface center of the web.

- Prehit Distance - Defines the distance away from the nominal surface at which the probe will start seeking the surface during measure.

Optional Settings

- Learn Using Values on Screen - This allows the user to enter the nominal values of the feature and have the software measure at that location.

Available Navigation Bar Soft Keys on this Screen:

| Backward / Forward Back / Forward to previous / next group of soft keys. |  | 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-.
| Return to Previous Step This will remove the last learned probe positions. |  | 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.
|  |  | Delete Current Command / Delete Last Created This soft key deletes the current selected command (or the last created command) from the part program. If this icon is disabled, you may need to delete commands using the Edit Program screen instead.
| Learning and Creating a Command This will only be available after all the necessary probe positions to identify the feature location have been learned. It will cause the machine to measure the feature. |  | Cancel All Steps / Abort This soft key stops and resets the current operation. If learning a feature, it removes all the learned probe positions.
| 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. |  | Return This soft key returns the view up one level to the previous screen.
| Tolerance Settings This soft key lets you set or modify feature nominal and tolerance values used by the feature command. It is an overview of what will show up in the report screen. |  | Insert Move Point This will read the current position of the probe and insert that as a clearance move into the program.
| Confirm / Add Command For operations this confirms the selection. For commands, this will append the command to the end of the program. For feature commands, this will become available after the machine has learned the feature location or when you have typed the feature's nominal values.
For constructed and dimension feature commands, this will become available once you have specified the proper input features.

Help

This soft key accesses the NC Gage help file.

Learn Process:

1. Press the Select Measurement Face soft key and choose the work face for the bore (Z+, Z-, X+, X-, Y+ or Y-).

2. Position the probe above the surface where you want to measure the point feature.

3. Press the Read Position soft key. The tip position is read as the start position. You can press Return to Previous Step to cancel this measure position.

4. Press Learning and Creating a Command . NC Gage automatically takes a hit in a similar fashion as depicted below.

Position A indicates where you should position the probe. The red line shows the measuring path. Position 1 indicates the measured point position.

5. Once the feature has been measured, the measured values are updated

6. Press Confirm and Append Current Command to End . The feature command is added to the part program.

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

Learn Point Feature Path

- Read current position.

- Measure in direction of current work face, search distance is 3* prehit distance.

- Retract to read position.

Execute Point Feature Path

- If current position is lower than the clearance plane height then move up to clearance plane.

- Move to position above point.

- Move down to a position above point that is prehit distance + probe radius from nominal surface.

- Measure point, target is prehit distance below surface.

- Move to clearance plane height after measurement.
