Deburr 4 Axis Example

Introduction

This tutorial explains how to create a Deburr operation and adjust that operation to output in 4 Axis.

Example File

If you are connected to the Internet, the part file for this example can be downloaded automatically by clicking the following link: Deburr 4Axis Example.bbcd

Once you download and saved the zip file, extract the files on your system in an easy place to remember.You can then open the file to use with this tutorial.All files for the tutorials in this help system available for download can be found by clicking on the following link: http://www.bobcad.com/helpfiles.

In the example fileprovided, the Tool Crib is already equipped with the necessary tools and the stock and Machine Setup are already defined.The part is simulated using the BC_4x_Mill machine.

Part 1) Add the Feature

Right-click MachineSetup and click Mill Multiaxis.
In the MultiaxisWizard, click Deburring.
Click Next>>to go to the Posting dialogbox.

Part 2) Define the Posting Parameters

The WorkOffset # is automatically set to the value defined in the MachineSetup dialog box.

You can change the value here to update the Work Offset # for the feature.
Click Next>>to go to the Multiaxis Postingdialog box.

Part 3) Define the Multiaxis Posting Parameters

Notice, at the top of the dialog box, that the Use Machine Settings checkbox is selected.

This means that the Multiaxis Posting parameters for the feature usethe same parameters as the machine that is selected in Current Settings.

You can clear the Use Machine Settingscheck box to define the Multiaxis Posting parameters of the featureseparately from the current machine settings.

For this example, no changes are needed (more information is providedlater).
Click Next>>to go to the Tool page.

Part 4) Define the Tool Parameters

In the Tool page, click Tool Crib.

The Tool Crib dialog appears.
Click ENDMILL FINISH and select the finishing tool.

At the bottom of the dialog box, click OK.
Click Next>>to go to the Parameters.

Part 5) Surface paths

In the Geometry input group, click the ellipses button next to Part surfaces.

The Mill Multiaxis wizard disappears and the Feature Geometry Picking dialog opens.
Select the check box for Select whole bodies.
Select the model.
Click OK.

The Mill Multiaxis Wizard returns.
In the Surface Quality group, set the Cut tolerance to 0.001.

This will reduce the calculation time and can be adjusted after we obtain the desired result.

Part 6) Tool axis control

At the top of the wizard, click the Tool axis control tab.
In the Tilting group, set the Machining type to 4 axis (rotary).
Click the ellipses button next to Axis.

The Line dialog appears.
Set the Direction to X.
Click OK.

The Line dialog disappears.
Click Compute.

Part 7) Simulation

To view the program, in the Quick access menu of the CAM Tree, click Simulation.
Click Play to view the current operation.

Notice that while we are able to deburr the outside of the part, the inner edges remain untouched.
To close simulation, in the menuSimulation group of the Milling Ribbon, click Exit Simulation.

Part 8) Edit the tool

In the CAM Tree, right-click the feature and select Edit.
In the tree on the left of the wizard, click Finish.
In the Tool page, click Tool Crib.

The Tool Crib dialog appears.
Click LOLLIPOP and select the tool.

At the bottom of the dialog box, click OK.
Click Compute.

Notice the additional places toolpath has automatically been placed now that we are using a tool capable of undercuts.

Part 9) Simulation

For more help using simulation, view Getting Started with Simulation.

To view the program, in the Quick access menu of the CAM Tree, click Simulation.
Click Play to view the current operation.

Notice the undercuts now being completed by the operation.
To close simulation, in the menuSimulation group of the Milling Ribbon, click Exit Simulation.

This concludes the example.
