Beginner's Eyewear Design Pop-up Class #5: Generating tool-path and exporting g-code in Fusion 360

Introduction

This tutorial guides you through the process of generating tool paths and exporting G-code in Fusion 360, specifically for eyewear design. This step is crucial for frame makers and designers, as it prepares your 3D model for machining, ensuring precise cutting and shaping.

Step 1: Preparing Your Design

• Open your completed eyewear design in Fusion 360.
• Ensure that all components of your design are properly grouped. This makes it easier to manage tool paths.
• Check for any errors or issues in the design that could affect machining, such as overlapping surfaces or non-manifold edges.

Step 2: Setting Up the CAM Environment

• Navigate to the Manufacture workspace in Fusion 360.
• Create a new setup:
  • Click on Setup in the toolbar.
  • Select New Setup.
  • Define the work coordinate system (WCS) based on how you’ll position your material on the machine.
• Select the type of operation you will perform (e.g., milling, engraving).

Step 3: Creating Tool Paths

• Select the appropriate tool based on your material and desired finish:
  • Click on Tool and choose a tool from the library or create a new tool if necessary.
• Define the tool path:
  • Choose the operation type (2D or 3D).
  • For 2D operations, use options like 2D Contour, 2D Pocket, or 2D Adaptive Clearing.
  • Specify parameters such as cutting depth, step-over, and feed rate.
• Simulate the tool path to visualize the machining process and check for any potential collisions.

Step 4: Generating G-code

• Once your tool paths are set, it’s time to generate the G-code:
  • Click on the Post Process button in the toolbar.
  • Select a post processor that is compatible with your CNC machine.
  • Configure the post processor settings according to your machine’s requirements.
• Choose the destination for the G-code file and click Post to generate the file.

Step 5: Exporting the G-code

• Save the generated G-code file to a location on your computer.
• Transfer the G-code file to your CNC machine using a USB drive or direct connection, depending on your machine's capabilities.
• Verify the G-code by reviewing it in a text editor to ensure it meets your machining requirements.

Conclusion

By following these steps, you can effectively generate tool paths and export G-code in Fusion 360 for your eyewear designs. This process is essential for transitioning from digital design to physical production. As you continue your journey in eyewear design, revisit previous classes to enhance your skills and explore more advanced techniques. Happy designing!
