In the Manufacturing Extension, the Probe Geometry strategy enables you to use probe cycles on your CNC machine
00:11
to measure and verify the geometry of critical features.
00:14
If there is deviation due to tool wear,
00:17
subsequent machining operations can be adjusted to compensate for the wear and to help ensure continued accuracy.
00:25
In this example of a part with toolpaths already set, the semi-finishing and finishing passes are split into 2 operations,
00:33
and a tool wear update will be applied between the operations.
00:37
In the 2D Contour dialog for the semi-finishing operation, the cutter Compensation Type is set to In control,
00:44
and for added accuracy, the finishing Stepover is set to the same value as the Stock to Leave.
00:50
This helps to ensure that the deflection is representative of the finishing cuts.
00:56
To generate a Probe Geometry operation, on the Manufacture workspace toolbar, click Inspection > Probing > Probe Geometry.
01:06
In the Probe Geometry dialog, on the Tool tab, click Select to open the Select Tool library.
01:13
Select a probe—here, Cube OP 20—then click Select.
01:19
Back in the Probe Geometry dialog, click the Geometry tab and verify that Select is active for Probe Surfaces.
01:27
Then, on the canvas, select the geometry you wish to inspect.
01:32
Back in the dialog, under Feature Tolerances, update the Position and Size—in this case, to 0.1 mm for both.
01:42
For this example, click the Actions tab, and then select Out of Position and Wrong Size.
01:49
This instructs the machine to stop machining and show a warning when the position or angle of the geometric feature is out of tolerance.
01:57
To improve the accuracy of future machining operations,
02:00
select Update Tool Wear to update the tool-wear compensation stored in the controller of the CNC machine.
02:07
Then, click Select and select a reference operation in the Browser.
02:12
This is typically the last operation that machined the feature, and provides important information, such as the tool number and stock to leave.
02:21
Next, set the Minimum Update Threshold—here, to .02 mm.
02:27
This function stops the tool wear from updating the controller for every micro-deviation found.
02:33
In this case, a value of .02 mm means that the tool wear updates only when the deviation of the tool is .02 mm or more.
02:43
A general rule is that up to 10% deviation is acceptable.
02:48
Finally, select Print Results to import the results back into Fusion for graphical representation.
02:54
Click OK, and the operation is generated.
02:59
In the Browser, rename your operation appropriately.
03:03
Then, click and drag it to the desired place in your machining workflow—in this case, just after the semi-finish pass.
03:11
In this example, the steps are repeated to create another Probe Geometry operation—this time, to probe for length.
03:19
Notice that the probe point can be dynamically dragged on the canvas.
03:25
After making selections and clicking OK, the operation is added to the Browser.
03:32
Again, the operation is renamed and reordered in the workflow.
03:38
In this example, it is optimal to do a final check of the bore as well.
03:43
The steps are repeated to create another Probe Geometry.
03:47
However, this time Update Tool Wear is not selected.
03:51
Now, you are ready to begin using the Probe Geometry feature to create probing operations.
03:58
Using these probing cycles on your CNC machine can help to ensure that your machining operations are accurate
04:05
by detecting and compensating for potential tool wear.
