Long story short:
Before my CNC-days I built a set of Line Source (LS) speakers utilizing decent quality drivers with a low price tag. Kinda nice when you need 40+ of them… The cabinet was made very crude and simple with ordinary hand tools and no real experience. They do work extremely well though…enough so to warrant a mkII dealing with sub-par cabinet qualities in terms of cabinet resonance and appearance.
Fast forward to present day:
As I now have a CNC at my disposal I wanted to put it to good use. More specificly, do a recessed mounting flange and surface contoured front baffle with precision
So Fusion360 is my go-to design enviroment and I made a model:
My CNC is limited in terms of X/Y machine area and the baffle way to long (2076mm to be exact) so tiling the carve process is my only option.
Here is my solution:
I made a 2nd board surface with side walls so my stock MDF sheeting stay parallell til Y-axis and I can shift the MDF incremently to do each “tile” with precision and accuracy.
Here you can see the first “tile” out of the machine, with pilot and guide holes shown:
The process is carve each segment out, lift and shift the MDF board according to pilot hole and repeat.
Since the full baffle have a top and bottom that is different compared to the middle ones I needed to split this into three groups, one for the top, four middle and one bottom. 6 tiling operations needed for one baffle and each tile represent about 30min of actual carve time. So 3hrs per full length baffle.
Once the baffles are done the CNC-part of this project is more or less done, but its apparent that I need to machine the stands on the CNC aswell
Reason for sharing - hope to give some inspiration for larger projects or guts to try more complex processes, where CNC may only a part of the bigger picture. Its a tool, use it
My hobbies / interests are diverse, and CNC is a big part of several of them as its capabilities allow me to do really cool stuff
