Autodesk Fusion 360 Process for Contour Machining

This page is a step-by-step walkthrough for setting up a contour milling operation in Autodesk Fusion for the WorkBee CNC specifically, but it should be easy to adapt this to any similar machine.

You will start with a New Fusion 360 Document and end up with a G-Code file ready to upload to the machine.

For further information and the explanation for each step, consult the Fusion 360 Documentation

Prepare

To get started, you will need to create the 2D geometry you’d like to mill out. For testing, a simple square with about 50 mm side length is a good starting point. Extrude it by the material thickness you plan to machine.

example test part


Then, in the top left corner of Fusion 360, switch from the “Design” workspace to the “Manufacture” workspace. This is where you’ll define your toolpaths and machine settings.

Import Workbee CNC

Before you get started, make sure you have properly imported the latest version of the machine definition and postprocessor into Fusion 360.

See WorkBee#Fusion_360_Setup for details.

Create your Milling Tool

At the top of the Fusion 360 Interface, select "Manage > Tool Library" to open the tool library. Navigate to "Local > Library". This is where you'll save all of your endmill data.

Click on "[+]" to add a new tool. Select the appropriate geometry, most likely "Flat End Mill".

The tool creation menu

Tab 1: General

Here you can name your endmill. Describe them well, you'll mix them up otherwise. Also enter sourcing information (such as aliexpress links) here, you'll thank yourself later.

Tab 2: Cutter

Take Measurements of your tool for dimensions using calipers (Messschieber) and populate the values accordingly.

Adjust number of flutes and the geometry to match your endmill. I recommend setting "length below holder", "shoulder length" and "flute length" to the same value, that being the length of fully formed cutting flutes of your endmill.

Tab 3: Shaft

leave as is

Tab 4: Holder

leave as is

Tab 5: Cutting Data

Cutting Data Tab


The following cutting data is a recommended starting point for a 1/8” (3.175mm) 2-flute flat nose endmill cutting plywood.

Many of the values (marked with fx) are calculated automatically and don't need adjusting.

Tweak these values as you gain experience:

  • Spindle Speed (Drehzahl): 16,000 RPM
  • Cutting Feedrate (Schnittvorschub): 1000 mm/min
  • Ramp Feedrate (Helixvorschub): 500 mm/min
  • Plunge Feedrate (Eintauchvorschub): 500 mm/min
  • Coolant: DISABLE (To prevent errors, the WorkBee doesn’t have a coolant system)

Tab 6: Post Processor

leave as is.


Sanity check all data once over and click "accept" to confirm.

Configure Setup

Create by selecting "Setup > New Setup"

Tab 1: Setup

  • Machine:
    • Select the latest machine definition
  • Workpiece Coordinate System (WCS)

Tab 2: Stock

  • Mode: Relative size box
    • Stock side offset: 10 mm
    • Stock top offset: 0 mm
    • Stock bottom offset: 0 mm

Tab 3: Part Position

Tab 4: Post Process

Optional: adjust program name.

leave as is.

Setting the Workpiece Coordinate System (WCS) origin

Set up 2D contour operation

At the top of the Fusion 360 Interface, select "2D > 2D Contour" to create a new 2D contour milling operation.

Workbee-tutorial-2d-contour.png

Tab 1: Tool

  • Tool: Select the appropriate Tool
  • Feed & Speed: Ensure the cut parameters are sane and have been properly inherited from the tool

Tab 2: Geometry

  • Contour Selection: Select the 2D contour you want to machine (the bottom edge of your design)
  • Tabs: Enable
    • Tab Shape: Triangle
    • Tab dimensions:
      • Width: 6 mm
      • Height: 3 mm
      • Distance: 40 mm

Tab 3: Heights - leave as is

Tab 4: Passes

  • Passes
    • Sideways Compensation: Right (Rechtsfräsen)
    • OPTIONAL: Preserve order Check this box if you have nested features (cutouts within cutouts) to maintain the cutting order
  • Disable all the other options

Tab 5: Multi-Axis

  • leave as is

Tab 6: Linking

  • Lead-In: Deactivate
  • Lead-Out: Deactivate
  • Ramp: Enable
    • Maximum Ramp Stepdown: Start with 3-6 mm and adjust based on endmill strength, desired cut quality, and material thickness

Confirm the Operation with OK. Fusion 360 will now display a preview of the operation.

How your preview should look

Simulate to check & Export

post processor menu
  • At the top of the Fusion 360 Interface, use the “Actions > Simulate” tool to check you haven’t missed anything
  • At the top of the Fusion 360 Interface, use "Actions > Post Process"
  • Use Machine Configuration (“Maschinenkonfiguration verwenden”):
    • Select Machine: “Comakingspace CNC”
    • Double-check Post-Processor: “WorkBee CoMakingSpace RRF”
  • Export

Your G-Code file is ready for upload to the CNC!
