Validating features

00:02

In this video, you’ll validate feature location and size,

00:07

and update machine parameters based on probing cycle output.

00:13

Many machine tools come with wireless probing systems that can help to set the work coordinate systems for parts.

00:21

Open the file 3D Advantage Probe.f3d in the Manufacture workspace of Fusion 360.

00:30

From the ViewCube, click Home to properly orient the model.

00:36

From the Browser, select Setup1.

00:40

Notice that this setup only machines one side of the part.

00:45

Review a few toolpaths by selecting them in the Browser.

00:50

In Setup2 in particular, notice that the work coordinate system is placed in the center of the part.

00:58

Since Z is being set off the bottom of the model,

01:03

the Z datum must be set in the machine off the top of the parallels before the part is inserted in the vise.

01:12

Once the Z datum has been probed in, the part can be placed in the vise so that X and Y and can probed off the stock.

01:22

Now, select both Setup1 and Setup2.

01:27

From the Toolbar, Milling tab, Actions panel, click Simulate.

01:34

Back in the Browser, under Setup2, select Adaptive2.

01:41

Notice that there is a protective hat of material on the part from Setup1

01:47

that prevents the probe from touching off on the machined surfaces of the part.

01:53

Because the X and Y axes have been set based on the raw, uncut stock of the part, they are not accurate.

02:02

Play the simulation.

02:05

The Adaptive2 toolpath removes the hat of material,

02:10

and then the facing operation provides a final cleanup of the part.

02:16

Close the Simulation dialog.

02:19

With the material removed, an in-process probing cycle can be used to shift the current WCS based on the machined faces of the part.

02:30

This ensures that X and Y datums are located exactly in the center of the part instead of the previous location,

02:39

which was based off of the saw cut edges of the stock with poor accuracy.

02:45

To do this, from the Toolbar, expand the Setup drop-down, and then select Probe WCS.

02:54

From the Probe WCS dialog, click the Tool selection prompt.

03:01

In the Tool Library, there is already a Probe tool within the document.

03:07

From the list, select 31 – Probe, and then click Select.

03:15

Back in the Probe WCS Dialog, open the Geometry tab.

03:21

In the canvas, select the faces you want it to probe.

03:27

The program updates its operation based on your selections.

03:33

Click OK.

03:35

Now that the probe has been used to accurately locate the X and Y datums of the part,

03:41

a chamfer operation can be used to deburr the perimeter of the part,

03:46

and the operator can be confident that the toolpath will line up with the previously machined geometry

03:53

that was cut on the first side of the part.

03:56

Once a part is completely machined, it needs to be inspected to ensure it conforms to the design requirements.

04:04

Manual Inspection is a process where an inspection plan is created for manufactured parts,

04:11

and then measurement data is recorded directly into Fusion 360

04:16

using a manual measuring instrument, such as a caliper, micrometer, or height gauge.

04:23

Here, you can see a series of inspection dimensions being placed on the part

04:29

that the programmer would like inspected after the part has been machined.

04:34

When creating a manual inspection, you can choose to measure critical dimensions of features.

04:40

In Fusion 360, you pick features directly from the model in the canvas

04:46

and set tolerances to define the allowable variations from the nominal values.

04:52

In addition, you can include checks in the inspection plan that are not directly associated with features on the model.

04:60

For example, you can include a simple pass/fail check

05:05

or type a user-defined action for when you want the inspector to record their observations.

05:11

There are a few different inspection tools available for inspection.

05:16

Bluetooth calipers send dimensions directly into Fusion 360.

05:22

Wired micrometers work similarly, syncing measurements to the program.

05:28

You can also use digital or analog gauges not connected to the computer.

05:35

If you are using a digital measuring instrument to measure dimensions in a manual inspection,

05:41

set up the connection with your computer.

05:45

If you are using an analog instrument, you will use the keyboard to enter the measurements.

05:51

Open the file 3D Advantage Inspect and navigate to the Manufacture workspace.

05:59

From the Browser, right-click Final Inspection, and from the shortcut menu, select Record Manual Inspection.

06:09

This displays the Record Manual Inspection dialog.

06:14

Here, you can see a list of already recorded inspection results.

06:19

Navigate through the list of results.

06:22

Once a result is selected, the canvas view updates to where the feature is located,

06:28

and the current inspection result and a value input field display.

06:33

Review each measurement using your inspection tool and check for accuracy.

06:40

Use the value input fields as necessary to update the results.

06:45

The dialog displays the deviation of the measured value from the nominal value,

06:51

and, if it is out of tolerance, it also displays the error by which the measured value exceeds the specified tolerance.

06:59

Now, navigate to the Inspection Result No Burrs.

07:05

Examine the part for burrs, and then select either Pass or Fail.

07:11

Then, in the dialog, click Next.

07:15

In the Inspector Name Result text box, enter your name.

07:21

Click OK.
