"Origami" CNC Plasma Build - folding 1200 x 600mm cut area

CAD designs on my take of this paper sketch.  I understand this type of adjustment concept does exist on some commercial machines so I can't be too far off the mark.

Looks good James.

you could also make the side plates bigger and have a l bracket on the top also.

If you checkout my gantry I welded nuts (M12) into the x axis, then slotted the y axis end plates so I had the up down adjustment to level the x axis with the table.

Cheers James

Getting prepped for some CNC milling action on the gantry sides.

Laying out the design on the fixture palette. In the Y it's a very tight fit and having to do this to this to the mm.


Working out where the internal clamping holes will be and laying spaces to support the blank off the pallet.


Some quick and "hacky" clamps.  Even though not pretty they are very effective and quick to setup.  Plan will be to make some a bunch of nicer looking ones for future use.


The blank in all its glory ready to be chewed up into a (hopefully) working part.

Just when it was about to get interesting, you stopped !
 

Sorry Tommy, work got in the way.  But first gantry side machined on the wee BF20-CNC.  Rather pleased with how it has come out.

Op1 completed with all the internal holes drilled, bored and pocket cleared.
 

Op2 completed. We have a completed part!!
 

Test fit on the table, perfect alignment with the linear rail truck.  Very happy camper.  Guess I need to get on to the otherside. Now I have working gcode files its really just rinse and repeat.
 
 

One of the obvious joys of cnc is that once you have a working recipe it really is just rinse and repeat.  So easy to see why industry has jumped into automated manufacturing for high volume repeatable processes.  Anyway, back on topic, the "other side". 

I moved to IPA for coolant/lubricant on my DIY fogbuster.  It's great as there is no residue. The chips are all dry and clean.  BUT it atomises much easier than soluable oil.  I'm going to have to do some design adjustments cose PHEW - smell.  Fortunately the weather was good enough to be able to pop the garage door!   So after a lot of IPA fumes (wearing a fume mask with painters filters) and a LOT of chips
 

We have ... the SECOND SIDE
 

And of course nothing is complete without showing it mounted
 

Now to move on to the deciding final orientation and then sorting out the motor mounts and drive pulleys.
