HIPÓTESIS ESPECÍFICA 1

Finish toolpaths for Multi Surface features can be modified to stay contained within an area or to avoid a specified area. Contain and avoid areas can be used to selectively machine within specified areas for re-machining, clamping or other purposes.

The Contain and avoid areas defined for the toolpath are illustrated for learning purpose.

Defining a Contain Area for the Pattern Project toolpath

1. Right click Pattern Project1 in the Operation tree and select Insert Contain

Area from the shortcut menu.

OR

Highlight Pattern Project1 in the

Operation tree and click the Insert Contain

Area button in the CAMWorks Command Manager.

2. The Contain Area Property UI dialog is displayed.

− Select the sketch named Contain in the

Allowed Sketches list. This sketch will

then be listed in the Selected Contours list box.

Pattern Project Flowline Toolpath

− Click OK to insert the Contain area.

− Click Yes if CAMWorks displays a warning message asking if you want to regenerate the toolpaths else Click the Generate Toolpath button on the CAMWorks

Workflow toolbar/ Command Manager. 3. Left click the plus sign to the left of Pattern

Project1 in the Operation tree.

The Contain Area item is displayed under

Pattern Project1. If you need to delete any

contain area later, you can highlight and delete that item.

4. Highlight Pattern Project1 in the tree. Observe that the toolpath is contained within the

rectangular sketch that was chosen for the Contain Area. The toolpath is trimmed to the contain geometry. The radius of the tool would pass beyond this boundary. Use the Offset value when choosing the curve if this is not desirable.

Defining an Avoid Area for the Pattern Project Toolpath

1. Right click Pattern Project1 in the tree and select Insert Avoid Area from the shortcut menu

OR

Highlight Pattern Project1 in the Operation tree and click the Insert Avoid Area button in the CAMWorks Command Manager.

2. The Avoid Area Property UI dialog is displayed.

− Select the sketch named Avoid in the Allowed Sketches list. This sketch will then be listed in the Selected Contours list box.

− Click OK to insert the Avoid area.

− Click Yes if CAMWorks displays a warning message asking if you want to regenerate the toolpaths else Click the Generate Toolpath button on the CAMWorks

Workflow toolbar/ Command Manager.

3. Click the plus sign to the left of Pattern Project1 in the tree.

The Contain Area and Avoid Area items are displayed in the tree under the Pattern Project1 item.

4. Highlight Pattern Project1 in the tree. Observe that the toolpath is contained within the Contain Area and avoid the area defined as Avoid area. The toolpath is trimmed to the contain and avoid geometries.

3 Axis Mill 6

CAMWorks provides numerous patterns that can be used to finish or semi-finish a Multi Surface feature. Each pattern has unique characteristics. While you may not use these for general machining, occasionally you will machine a part that is appropriate for one of these styles.

This tutorial explains how to generate radial, spiral and 2D stepover toolpaths.

What You'll Learn

• Generating radial finish toolpaths using the Pattern Project operation.

• Using Step Through Toolpath

• Generating spiral finish toolpaths using the Pattern Project operation.

• Generating 2D stepover toolpaths using the Constant Stepover operation.

Defining the Mill Part Setup and Inserting the Multi Surface feature

1. Open the Open the part file MILL3AX_6.SLDPRT in the \Examples\Mill folder.

2. Click the CAMWorks Feature Tree tab.

3. Double click Mill–in in the tree. OR

Click on the Define Machine button on the CAMWorks Workflow toolbar. The Machine dialog is displayed.

− On the Machine tab, ensure that Mill–in is the Active machine. − Click the Tool Crib tab and make sure Crib 1 is the Active tool set. − Click the Post Processor tab and make

sure M3AXIS-TUTORIAL is selected. − Click OK to close the Machine dialog box. 4. Double click Stock Manager in the tree

OR

Click on the Stock Manager button on the CAMWorks Workflow toolbar.

5. The Manage Stock dialog is displayed. − Click OK to use the default Stock

6. Right click the Stock Manager item and select Insert Mill Part Setup from the shortcut menu

OR

Click on the Insert Setup button on the CAMWorks Workflow toolbar. Select Insert Mill

Setup from the dropdown

menu.

The Mill Setup Property UI dialog is displayed. − In the graphics area,

expand the tree for

MILL3AX_6 and select Plane1.

− Make sure the Face option is not checked. − Click OK to insert

the setup.

Mill Part Setup1 is

inserted in the tree.

Inserting Multi Surface Feature

1. Right click Mill Part Setup1 in the Feature tree and select Insert Multi Surface Feature from the shortcut menu.

2. The Insert Multi Surface Feature dialog is displayed.

− In the Feature Type group box, select the All Displayed option from the dropdown list.

− Set the Strategy to Fine.

This Strategy has been set up in the TechDB to generate one Pattern Project operation.

− Click OK to insert the feature. − Click to close the dialog.

Multi Surface Feature1 is listed in the Feature tree.
