Week 08
Computer-Controlled Machining
Group assignment
- test runout, alignment, speeds, feeds, and toolpaths for your machine
Individual assignment
- Make something big (on a CNC machine).
Learning outcomes:
- Demonstrate 2D design development for CNC production
- Describe workflows for CNC production
Have you:
- Explained how you made your files for machining (2D or 3D)
- Shown how you made something BIG (setting up the machine, using fixings, testing joints, adjusting feeds and speeds, depth of cut etc)
- Described problems and how you fixed them
- Included your design files and ‘hero shot’ photos of final object
Tools used
- large self made CNC
Software Used
- Solid Works
- HSM
- Mach3
-
Introduction:
For this weeks assignment I started by looking for inspiration on a CNC electronics enclosure. This is part of my final Project, The Large CNC The idea I have in mind was to have all the electronics inside a box that could be adapted with time with different "windows" that could be exchanged as I change the equipment without having to change everything. After a web search I found a few inspirations that I present below:
-
The caracteristics:
currently most of the electronics are mounted to a piece of MDF and some are just nearby so I really need a box :-).

The design:
The design is going to be made in Solidworks and parametric so I can reuse it in the future for other projects.
