Week 07: Large format CNC (computer controlled Machining)¶

This week I worked on defining my final project idea and started to getting used to the documentation process.

Group Assignment¶

We completed the lab’s safety training to ensure a thorough understanding of the necessary precautions and protocols. Next, we conducted a detailed test of the machine, checking runout, alignment, fixturing, speeds, feeds, materials, and toolpaths to confirm optimal performance and accuracy.

Individual Project¶

I designed, milled, and assembled a large project, demonstrating the development of 2D designs specifically for CNC production.

↪ Inspirations¶

From Pinterest.

↪ Designing My Table¶

I can’t share all the steps I took since there was a lot of trial and error, but I can provide the main idea to help you create any design you want. If you’re specifically interested in this design, you can download it below.

Sketch each part individually and use parametric values for the measurements to allow easy adjustments.
Extrude the parts.
Set parametric values.
Move & copy parts.
Split a component.
Combine bodies.
Fillet Corners.
Use mirror to create symmetrical components efficiently.
Create a project sketch by pressing P, selecting the sketch of your parts, and then saving the file as a .DXF.

↝ First Table¶

I like this table idea, but I had a problem in designing it with the material we have.

Then I used Fusion 360 to create my table. click here to download it!

↝ Second Table¶

I came across this design in my Inspiration File stored on my computer.

I used Fusion 360 again to create my amazing table. Click here to download it!

↝ Is there a Failure?¶

Was it a waste of time to create two tables? Not at all. The second table was part of a Plan B because the first table failed, leaving me with a tight deadline to complete the project.

The issue stemmed from a software problem where the machine couldn’t distinguish between cutting and engraving paths. This challenge taught me more about how the machine operates and improved my understanding of its functionality.

The experience gained from working on the first table was invaluable and made creating the second table in such a short time possible. So, no, it was never a waste of time—it was a learning process.
