home made cnc..

[smitty919]

OK im in the middle of trying to make a home made cnc.
so far i have a rolling chaise as i will show you in the video.
as of now its only 2 axis but in the future it will be 3 axis.
plans are to have it work both with a lathe and cut flat shapes..

i do have all the motors and computer stuff to get it up and running only thing i need is the know how of programing lol.

[numbskull]

Like the dog wandering around in the background.

Looks like you are trying to build a better RAT trap



Smitty looks good so far you got a long way to go to get to the computer stage though. This is what I was talking about in the other thread on here a while ago for home-owner type machines. That's a great little inexpensive 2 axis mill. You'll have a blast with someof the pre-canned stuff out there.

What kind of tolerance are you expecting to keep with that and what did you use for motion stuff?

motion stuff as in what is the axis sliding on??
i made a bunch of roller rails that work against each other as to not let the parts twist or lift off.


as far as tolerance as close as i can get lol.

it will have a router on it at first with a straight cutting bit on it to make a pass down the wood and on its run back to home it will move in a hair to make a smooth final cut i hope lol.

very little if and play between the two Pieces im verrrry happy with that.

[smitty919]

whats that mean in English lol not a big fan of fancy words lol.

[smitty919]

ohhhh i see what you meen.

yes i have a driver board for it and it will do 3 axis.

and i bought a dell lap top to run the whole thing.

only thing i did not get yet and will are limit switches...

all the motors and computer driver board and a few other things i will be working on over the next week or so.

i need to also make a power supply for it i have all them parts also..

once i have all that done i need to find a program thats easy ti under stand and start to dial in the motors and limits it will have.

so yes i still have a ton of work to do..

once i get it up and running and feel its worth taking the next step i will be doing it all in metal and building a enclosure for it.

I'm a machinist.I'll be out of work for the next couple of months recovering from shoulder surgery.
20+ years in the industry,i've spent the majority of my life running a small shop that specializes in building "skunk works" type projects with machine tool companies.Did some work for HAAS a few years back.
I'm bored stiff and would jump at the opportunity to offer my experience as a technical advisor,free of charge of course,to get your project done.
I can still click a mouse
Replicable tolerance,or repeatability as it is commonly known in the industry is determined by many factors.Frame rigidity is a major one.
Pm or e mail me if interested.

You poor soul. I am sorry.

Funny I am contemplating shoulder surgery myself. Must be a trade thing.

Sorry to hear that guys look on the bright side if you were upper management it would of been knee surgery.

I was insinuating I was sorry for him being a machinist.

As far as the shoulder thing that sux's and sorry for that too.

LOL Lu. Our upper echelon, the one dim wit we have , wears knee pads, and I am surprised he can figure out which side they face. thank god I work nites with no nit wits

lol there are times when i'm sorry too.
For the most part though i love what i do.We are a prototype building shop,guys on the floor work with the engineers(or should i say nit wits)designing and building one of a kind machinery and components.The big boys call it outsourcing
No repetitive production machining is done there.Something new every day.
An awful lot of plugs and custom reel repair parts are made during our slow periods,we all love to fish.
As for the shoulder,injuries go with the territory.20 years of locking down lathe chucks and vises coupled with lugging steel will eventually tear something.

No production for me either. Old school. 30 years in Job shops. Accurite is the closest thing to CNC I use. Every few days a new headache. I wish I had some of the engineers that design some of the stuff we make, i'd throttle them. They need to spend a few years in a shop before they start to design this stuff. I have to do half their math for cripes sake. Used to be I always wanted the toughest job in the shop now I want the easiest.

Sorry for the thread hijack. Back to the lure making thing a ma jig

LOL But after all these years its all the same it gets too easy tell me what can't you guys make? That is a much harder question.

Not a bad idea at all!

I can tell you from experience that there will never be an engineer that knows what a good machinist knows. Look for the busiest machinist in the shop and you will find the guy that engineering has the most confidence in. The machinist on the other hand should expect the engineer to learn as he goes. If you are doing the same simple calculations every job, talk to the man!

The engineer should also know; tap drill sizes, corresponding counterbore dias. and depths. Alloy specs, hardness designations. Finish criteria. The list goes on!
