4.2.4.1 Chamfer (ger. "Fase")

In this exercise you'll learn about the feature Chamfer.
It's used for adding chamfers to edges.

Open the model pad, and save it as chamfer according to the naming convention.

Select the feature Chamfer .

A menu as shown on the right pops up. (refer figure "Menu Chamfer")

Creating a simple chamfer

After opening this menu, choose . Now you can create simple chamfers. Select the edges that you want to create chamfer on. Click all four sides of the pad that are parallel to the x-axis. A preview of the final chamfer will be rendered automatically.

Pad with chamfer

Enter 5mm as Distance and confirm by clicking OK. As you can see in figure "Pad with chamfer", the function chamfer can not only subtract material, but also add material when an inner edge is selected.

Attention:

The preview is not always automatically refreshed. Sometimes the chamfer in the preview window does not have its respective size, but the size that was used for the last applied chamfer. This is why the preview may generate a chamfer that is too large or even generate an error, because it is too big for the model. Ignore this warning, it disappears as soon as the feature is created.

Hint:

The default angle for simple chamfers is 45 degrees.

Creating a chamfer by specifying two distances

To create a chamfer defined by two distances, choose . Click the four edges of the block where the pad is not located . In what order you click them is not relevant. Enter the following values as distances:

Distance	Value [mm]
First Distance	5
Second Distance	10

asymmetric chamfer

The chamfer will be created by clicking OK. (refer figure "asymmetric chamfer")

Hint:

If NX switches the two distances, you can use the option to switch the two distances again.

Creating a chamfer by distance and angle

Open the model cylinder, if you created it previously. Otherwise create a model cylinder and add a cylinder with the following dimensions to it:

Dimension	Value [mm]
Diameter	20
Height	50

chamfer on cylinder

Select the feature Chamfer alt .

Choose . Click both outer edges.
Assign the following values:

Dimension	Value [mm]
Distance	2
Angle	15

Clicking OK creates the chamfer. (refer figure "chamfer on cylinder")

Hint:

A so called Feature Alert may be displayed when adding chamfer to a cylinder. This is not a problem. (see chapter 4.2.6 "Feature Alert")
