CNC | 2D Milling In Fusion360

Video Tutorial

Preparation | Rhino

1. Create your stock material within Rhino

2. Place your contour at the top of the stock material

3. Export the stock as an .stl

4. Export the contour as a .dxf

5. Ensure you’re naming these exported files something logical

Design | Stock

1. Must be in the Design workspace

   1. Open

      

2. Verify units for your scale

   1. Open

      

3. In Fusion, select insert mesh

4. Select your stock model .stl file

5. Click OK

6. Change the opacity of your stock material by right-clicking the item on the navigation tree -> opacity control -> 50%

   1. Open

      

Design | Contour

1. Still in the Design workspace

   Open

   

2. On the top navigation bar, select Insert → Insert DXF

3. Select the X,Y plane

   1. Open

      

4. Click the folder icon

   1. Open

      

5. Click “Select from my computer…

   1. Open

6. Fusion will need to think about your .dxf for a moment, then the Insert menu will change a bit

7. Confirm that the units are correct

8. Click OK to insert your file

9. To view all of your imports, expand the Bodies and Sketches sections of the navigation tree

   1. Open

      

Manufacture | Setups

   1. Open

      

4. On the top navigation bar, select new setup

   Open

   

5. Setup tab

   1. Configure Work Coordinate System (WCS)

      1. Select the 0,0 ref point on the bottom of your stock material

      2. WCS should be on the X, Y plane

   2. Model

      1. Use the navigation tree to select your line work (best method)

   3. Open

      

6. Stock tab

   1. Stock

      1. Use the navigation tree to select your stock (best method)

Manufacture | Create From Template

1. Must be in the Manufacture workspace

   Open

   

2. Right click the setup you just created and select 'Create from Template'

3. If you haven’t used the template before, you need to click on “Select Template” and select the 2D Template

   1. If you have used the template before, it will be selectable next to “Create From Template”

4. Select the template titled 2D Contours

5.  

6. You should see new operations load in from the template

7. Select the edit icon (highlighted in red) to open template configuration

   1. Open

      

8. Starting from left to right, we need to configure settings for this operation

   1. Open

      

9. Tool tab

   1. Select the tool required for your job as referenced on Templates for Fusion360 wiki page
      Tool = the bit used for this operation

   2. Select a material preset
      Preset = feeds & speed variables are baked into preset profiles

      Open

      

10. Multi-Axis

    Open

    

    1. This is the machining type and shouldn’t change from the Template; you can skip it

        

11. Geometry

    1. Select Geometry

       1. Geometry = Line work for tool path

       2. You have two methods to select this linework

       3. Click directly on the contour (this will select it as a Closed Chain

       4. Use the navigation tree to select your line work (this will select it as a Sketch Profile)

       5. Geometry settings cog will display a window to select cutting on the inside or outside of a specified line

          1. Open

             

    2. Select Stock Contours

       1. Stock Contours = Creates a boundary box, keeping the tool within a certain perimeters

       2. Select the boundary stock contour

12. Heights

    1. This tab can be very helpful when you only need to etch the contour rather than cut it all the way out, or if the stock is deeper than the bit

    2. The one we recommend changing for either reason listed above is 'Bottom Height”

       1. Stock bottom is selected by default, but there’s 0.00” Offset

          1. You’ll change the Offset to the thickness of the stock material you want to leave OR

          2. The difference between the stock depth and the tool length

             1. Example, you have 3” foam and a 2” bullnose bit on CNC2, you’d want a 1” offset

    3. Open

       

        

13. Passes

    1. The number of passes depends on your material, and you almost never leave this as a single pass at full depth

    2. For foam, a 1/4” (0.25”) or 1/2” (0.5”) maximum pass depth should work well

    3. For solid or laminated wood, you’ll want to use 1/16” (0.0625”) maximum pass depth

    4. For a single sheet of plywood, a 1/16” (0.0625”) or 1/8” (0.125”) maximum pass depth

14. Linking

    1. Is configured for the School of Architectures ShopBot CNC machines and should not be changed.
