Week 8

This week I desined and make something BIG on a CNC machine. I decided to design and make house for our kids.

Design

I designed it with SolidWorks, very efficient CAD.

Full assembly:

2D design for CNC production:

Files:

Wall with window 1 Wall with window 2 Wall with window 3 Wall with window 4

Wall with circles 1 Wall with circles 2 Wall with circles 3 Wall with circles 4

Wall 1 Wall 2 Wall 3 Wall 4

Wall with door 1 Wall with door 2 Wall with door 3 Wall with door 4

3D Model

House assembly by Pavel on Sketchfab

Making

Every Cad file I need to run through Fusion 360 to get a generated G-code for my milling machine

Insert DXF

Create sketch

Extrude at 20mm, as it will be done from 20mm plywood

Create “setup” for manufacturing: define axis and “zero” point

Create contour operation around stock

Important note: we should make multiple passes, because cut is too depth for passing it once, endmill can be broken otherwise. Maximum stepdown is 10mm

Generated toolpathes, seems perfect. GCODE: FILE

Repeat for each detail :)

Computer-Controlled Machining process:

Assembled house:

Conclusions

  1. Computer-Controlled Machining is relatively easy technological process, but you have to use really BIG CNC machines if you would like to make something BIG.
  2. Otherwise - cut your BIG invention and assemble it after cutting.
