So, looking at my machine last night, i was thinking about different silly/useful attachments i could make for my CNC machine...
I come up with the 'X-Saw'
This is one of them ideas that i dont think this will be useful to anyone else but me, with a limited tool shop!
This idea is to have a hacksaw blade/ cheese cutting wire attached to the Z axis, and using the linear motion of the X axis to make a nice flat cut on stock material, or for my application builders foam...
Ok i expect your thinking why not just use a hot wire cutter. Well i would but the foam i use to make models/plugs etc...wont cut with heat
Gcode would be simple enough, making a .tap file with Sheetcam, with different Z values depending on depth pass per cut..
I need near enough true blocks of foam 300mm x 300mm for my vaccume forming table...
Im at work so excuse the non 3d models design, but you get the idea...
Good thought, but thats kinda what i use now, well with cheese wire not a blade, the only trouble i find with that, is there is alot of vibration going on, and even though it cuts OK i still get a top or bottom taper?
Well for for hot wire cutter a i have a jig that cuts spot on, flat as flat can me, its gravity fed...
Umm around 600mm is the cheese wire, under tention around B (says my guitar tuner )
The building foam is not like to your normal Blue/pink/white foam - it is very dense, you can just about make a nail dent in it - cuts lovely with a normal saw
With a barbed cheese wire, using your had and the bow i can get lovely cuts!
I guess i was hoping to use the stability of my machine to cut slowly...
similar to this one. I don't know if it is available in longer lengths. There are diamond coated wires also. I don't think the sawing action needs to be as fast as a carving knife. Anyway, food for thought.
Can you elaborate on the foam you are using? Type, brand name etc.?
How do you find the Celotex machines? Can you post pictres of anything machined in it? I can see it being useful as a tester before commiting to a large expensive block of stock!
