Using the Faro connection

I have a casting blank that differs from my CAD data set. I scan the blank, import the data, and then use the SCAN/MESH/ALIGN function to compare the position of the CAD data set and mesh. Now I’ve heard that this could be performed more easily in Tebis with the Faro connection. How exactly does it work?

A major benefit of the Faro connection is that you can fully utilize the options provided for external setup. Any setup situation that you use frequently should only be mapped once in the virtual environment. You can then access this setup situation for all other machining operations. Another advantage is that you can immediately tell from the fixture whether the blank fully envelops the CAD data. In order to align the real die plate to the virtual die plate, you need to have stored the virtual die plate in your database.cnf. This lets you simulate the setup situation for future machining.

Here's how you do it

1.

Create a permanent setup situation with the real perforated plate on your measuring table.

2.

Open the database.cnf file from your Tebis installation at your setup station.

3.

Use the SCAN/RECORD/PLANE function to capture three planes of the real die plate with the tactile probe of the Faro arm.

4.

Use the SCAN/RECORD/CONFIG function to open the Faro toolbar.

5.

Click "Orientation." This opens the ORIENTATION dialog.

6.

Select the "Three planes" option as the orientation mode.

7.

Select the three planes of the real perforated plate that you captured by the tactile probe as the actual elements and the three corresponding planes of the perforated plate in the CAD data set as your target elements.

8.

Confirm your entries. The elements are aligned with each other.

After you have aligned the real and the virtual die plate once, you only need to capture the blanks for future machining steps.

9.

Set up the blanks at the setup station.

10.

Open the data set with the relevant trim steel. Ensure that the database.cnf file containing the aligned real and virtual perforated plate is stored.

11.

Use the EDITOR/TRANS function to position the trim steels on the virtual perforated plate as required.

12.

Use the SCAN/RECORD/DIGIT function to scan the cast blanks. During the capture you can immediately see whether a blank fully envelops the CAD data.

13.

Now generate a mesh from the digitized data using the SCAN/MESH/TRIANG function.

14.

Use the SCAN/MESH/FILL function to create a closed blank.

Hints

As an alternative, only scan the areas to be milled and create a blank for the entire component.

Open the context-sensitive help in the SCAN function group to find out more about digitized data processing and scanner coupling modules.

Open the context-sensitive help in the EDITOR/TRANS function to find out more about transforming elements.
