Week 07 - Computer Controlled Machining
Group assignment
Test: Runout, alignment, fixturing, speeds, feeds and toolpaths. On the link below you can find the complete process of this week's group assignment, covering usage and setting up parameters.Click here
Make (design+mill+assemble) something BIG!
Precedents: MAEBB - Valldaura labs/IAAC (2021)
Before FabAcademy I did a master program from IAAC where I had the same excersice. In that time I explored press fit pieces with CNC, as well for the rest of the program since it was based on building with wood.
"Pupi-TRE": A portable kit designed for classrooms that don't have tables for taking notes. Included: a clipable 3D printed piece for beneath the chair + CNC wood pieces to assemple easily which will slide in the piece.
Design: "Bed/couch table"
3D modelling: Rhino + Grasshopper
1. Sketching ideas and taking measurements: I asked my instructors if I could push toward a different path so I could expand my carpentry skills.
2. Rhino: SubD modelling for a morph shape, playing around with mesh faces.
3. BowerBird + OpenNest: using the same script from week 3 "Computer Controlled Cutting". Connected the new brep and adapted the iterations on the nesting.
RhinoCAM settings
Material & tool set up (digital)
1. Stock: Select all the elements you want to cut and set up the size of your board (underlined with red). A yellow/orange box will appear indicating the area that it will operate.
2. Milling machine tool: for our CNC machine we are using a 6mm Flat down-cut mill, update parameters according to the machine's capacity.
Set up according to functions
1. Drilling: one of the first things to set up
2. Hole pocketing:
3. Internal profiling:
4. External profiling:
5. Common parameters (internal & external):
6. Post:
CNC machine set up
Material & tool set up (physical)
1. Set up XYZ + Load "Drilling" file:
2. Start screwing
3. Load "Pocketing" file:
4. Load "Profilling" file:
5. Remove pieces: Unscrewing board + Chiseling bridges + Cleanning area
