Configure a cross-shaped probing routine that starts at the mirror center, advances in 5 mm increments, and records each measured Z value with its X and Y coordinates. The evidence confirms that a .TAB table is required and that selecting Example.TAB produced a working result, but it does not identify the controller, programming environment, probing command, or table syntax.
Define the cross-scan coordinates
Treat the mirror center as X0 Y0. Probe four radial paths from the center: X positive to X675 Y0, X negative to X-675 Y0, Y positive to X0 Y675, and Y negative to . Use a 5 mm position increment and associate every measured Z value with the commanded X and Y position.
| Path | Start | End | Increment |
|---|---|---|---|
| +X | X0 Y0 | X675 Y0 | 5 mm |
| -X | X0 Y0 | X-675 Y0 | 5 mm |
| +Y | X0 Y0 | X0 Y675 | 5 mm |
Each radial path contains 675 / 5 + 1 = 136 positions when both endpoints are included. Four separate center-to-edge runs therefore create 544 records if the center is logged on every run. If the center is stored only once, the cross contains 1 + 4 × 135 = 541 unique coordinate positions.
Prepare and select the TAB table
Create or provide the required table before running the measurement routine. The demonstrated workflow used a file with the .TAB extension and selected Example.TAB in the selection window. Because the evidence mentions both Tabelle.TAB and Example.TAB, confirm whether one is the intended output table and the other is a supplied template in the actual software environment.
Do not assume the measurement program creates the file automatically: that behavior is not established. The required logical fields are X position, Y position, and measured Z value, but the evidence does not define field names, separators, data types, or whether the table must be preallocated.
Run and verify the measurement
- Establish the work coordinate origin at the mirror center and verify
X0 Y0before probing. - Load the required
.TABfile through the program's selection window; useExample.TABwhere it is the supplied working table. - Execute the four center-to-edge paths at 5 mm increments, recording X, Y, and the measured Z value at each position.
- Verify the table contains the expected endpoints and either 544 records with repeated center measurements or 541 unique positions with one center record.
The mirror diameter is stated as 1350 mm, which supports the 675 mm center-to-edge travel. A separate value of 12000 mm is labeled only as “DM” and is not defined; do not use it for motion or compensation until its physical meaning is confirmed.
FAQ
How many points are required for a 1350 mm mirror at 5 mm spacing?
The four center-to-edge runs contain 544 records when each includes its center point. Removing three duplicate center records leaves 541 unique X-Y positions.
Does the probing program create the TAB file automatically?
The evidence does not confirm automatic creation. Prepare the required .TAB table and select the supplied Example.TAB in the selection window before running the measurement.
What data should each mirror probing record contain?
Store the commanded X coordinate, commanded Y coordinate, and corresponding measured Z value. Confirm the exact field syntax and file layout in the available table template because they are not specified in the evidence.
