### Point

To create a Point command:

1. Press the Measure soft key from the Main screen.

2. Press the Point soft key from to display the Measure Point screen.

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:

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. Press the Return to Previous Step soft key to cancel this measure position.

4. Press the Learning and Creating a Command soft key . 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 the Confirm and Append Current Command to End soft key to add the feature command 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.
