Machining a chamfer in CAMWorks

CAMWorks 2.5 axis feature lets us define numerous features on our part and subsequently generate the operation plans required to bring these features to life. One particular parameter (chamfering) can be easily defined using the 2.5 axis feature under the mill part setup.

We will go with a simple part demonstrating how we can add a chamfer operation into our operation plan without necessarily using the Extract machinable feature tool.

Begin by creating a simple enough part like the one below.

In the CAMWorks tab, we begin by defining our machine and setting our stock definition (size). We can then go ahead to create a new mill part setup.



Under the mill part setup, choose to create a new part parameter. Select an open pocket with a rough-finish strategy.


Choosing this sets up will generate two milling operations, one that does a rough mill followed by a contour finishing mill.

Generating the operation plan will set up these two mill operations.


Next, we copy the contour mill from which we can define the chamfer. We can copy by dragging the mill operation using the control key onto the mill part setup.

From the copy that is created, we can define the parameters of the chamfer. The first thing we do is change the tool in the tool crib with one that can do a chamfer, for example, a countersunk tool.


From the contour tab, we need to define the parameters of the chamfer, for example, the length and the clearance.


Once we have done this, we can generate the tool path and do the subsequent simulation to see how the operation is done.


Once we have finished defining the chamfer for the outer edges we can go ahead to define the chamfer for the inside pocket.

Our final model should look like the one below.
