1.14 - Welcome!

Class will meet every Monday afternoon. We will spend the first portion of the semester on the control side of the manufacturing using CAM tools and GCODE. We will build a tool library to prepare us to quickly use the CNC and iterate on our designs for manufacturing. We will move quickly and the CAM portion of the class will require outside practice using simulation. We will be using Fusion 360 as our CAM package and use the Tormach GCODE machine programming reference.

Getting Started:
We are going to practice processes and developing an overarching idea for the class using modeling clay and constrained tools to create certain shapes.

1.28 - CNC & CAM

Getting Started:
Introduction to CNC and CAM tools, while designing small parts for the laser cutter in CAM. We will look at how parts fit together and develop a unique model to be processed by the laser cutter. We will also start talking about tooling for the CNC Milling Machine.
Make sure your account with Autodesk is working...
Basic model in CAM using post processor for Universal Laser
Create a part using the laser cutter...
Change the part based on kerf...

Supplemental Materials:

Paper Calipers - duckythescientist - Thingiverse

For next class:
Make sure that your caliper is completed in cardstock, and is scaled to the proper size.
Make sure your Autodesk account is active on Educational Version.
Read 3-10 to 4-13 in Autodesk Fundamentals of CNC Machining Book.
Bring your digital caliper to class! We will be using it extensively.
If you are redoing any of the CAM from class, I will be posting a video on what we did in class for your review.

2.04 - CAM & Tooling

Getting Started:
We are going to create another simple piece and prepare it for the Carbide3D Nomad 833. We are going to create a reference face, add a tool to the library, and make a simple shape on the machine. You are also encouraged to finalize your caliper from last week, and recut it if need be.
Create a new sketch, extrude with dimensions
Setup your CAM environment, add the Carbide post processor
Add an existing tool to the tooling library for future use
Cut part out of existing stock material and check its dimenions

For next class:
Have your facing operation complete with a 1/4" Spiral Upcut Bit and selected stock, drawings and models are listed above.
Attempt to face your material in the Carbide CNC.
Be prepared to continue with the other operations for next class, review this video for getting setup in Fusion 360.

2.11 - CAM & Tooling, pt 2

Getting Started:
We are going to attempt to use our facing operation in the Desktop CNC then finish our other operations.
Face bottom of the part on the Desktop CNC (Carbide 3D)
Create another setup and 4 operations for the remainder of your part
Mill the other side of your part using the Desktop CNC

For next class:
Finish CAM from this class, mill your part if you can!

2.18 - CAM & Tooling, pt 2

Getting Started:
Discuss your posted GCODE with another student. Try to break down the facing operation, by codes and commands.
Review previous operations in CAM and discuss...

Supplemental Materials:
Final Wheel CAM - .nc
Final Wheel, Model & CAM - .f3d

Make the wrench out of 7.5" x 2" x .2" aluminum in the CAM software.
Export to an NC file and double check your GCODE. Use the Lakeshore Carbide, 3 Flute, .25" Carbide Tool in your setup for all operations.
If you have not created your wheel from last class, make sure you mill your part with lab hours.

2.25 - 2D CAM

Getting Started:
Create the GCODE for the Carbide CNC using the class example and comparing other code. Don't use Fusion to create the GCODE, but you can reference some of your previous examples...
Review any previous class operations and continue to develop your documentation.

We will be cutting using the Lakeshore Carbide, 3 Flute, .25" Carbide Tool. Calculate your Speeds and Feeds needed!
Use the Tormach post processor to create your GCODE.
Everything will be cut out of 1/4" Aluminum Plate. If you'd like to add a chamfer around the two edges that would be a bonus!

3.04 - Milling Machine 2D Profiles

Getting Started:
Prepare your stock for your 2D operation, cut using the jigsaw and an aluminum blade and a friend.
