Hi

Anybody knows some online US shop that does custom aluminum ans steel parts for reasonable price, using the CAD file?

I'm using emachineshop for some of my projects. They have coninient software, where you can design and immediately, quote, and order the part. But their prices for single pieces are not good.

Are there any other shops with online (or simplified) ordering?

In the US.. no; I knew ther was one in Portugal that was really cheap
(happened to appear on ebay every once in a while searching customers)

But the thing is, a single part is always the most expensive.
The majority of the price is for setting up the toolpath and the machine,
the material is just a minor part of the equation (well if it's not a huge part of course)

Pat could explain this better than me,
but basically you need to pay the time you use the utterly expensive software and the one who's running said software too.

For a single part it's cheaper most of the time to make it on a conventional machine rather than a CNC (well for 2.5D parts that is..)

No matter where you go it will be way expensive for one or two parts.
When pricing the shops use a multi quanity discount. The more you order the cheaper because they buy enough material to do big runs and are already setup for the quanity.
A single part will be more since there is setup time for machines, programming the part, material cost etc.
When i ran a metal fabrication shop people did not understand this. They would want lets say 5 parts that used about a 24x48 piece of aluminum but i had to buy a piece of 48x96 if it was not in stock.
And yes we kept the leftover material.

Or I understand all that! Just looking for options. I have too many ideas for my project and too little money. Right now I'd want to make an (2) aluminum parts that is just 2.5x2.5x1" and very simple flat design... and the best I could find is $160...

People always say they understand that, but still want mail order part pricing. $160 buys you 2-3 hours of machine time, at best.

I don't machine anything for anyone but myself anymore because of this. My cost to machine custom components (as stated above already) is higher than the selling price from large retailers. I got sick of making $3/hour for my time. This doesn't even take into account how much money there is to be lost if something goes wrong, and occassionally it does.

Good luck. The cheap stuff ain't good, and the good stuff ain't cheap.

I found out how much time it takes to machine a few things on my bike. And probably if I could find it I might have bought it.
I did however have the tools,time and material for free, I just have to put in my time.

Im going to guess on the part, if anything costs what you quoted above, then it is probably worth the money as it most likely wont be any cheaper.
Most places charge several hundred for just the setup alone.

I see.

You'd think in 2013 they'd have machines that'd just DO stuff from CAD file. Without the setup :)

We u have the 3d printers but that's about it

U have to set the machine up for each component

The only time that is going to change is when's robot does the setup

Cad files dont have tool paths and other info for what ever machine it is to be run on, depends on the age and type of machine,ect. ect.

How would the machine know where to start, how you are holding the workpiece, which cutting tools you want to use?

It's called CAM, but still needs a person on a computer using the 3D model to decide these things.

I know I know. But being a programmer - I know that all this HOWs are theoretically solvable. We landed on the moon 50 years ago!

If its just 4 pcs ,cut from flat stock, why not try a place with a water jet? Or maybe even an EDM machine?

Vlad, if your part is that simple, you shouldn't be looking for a CNC quote in the first place. On the other hand, since we haven't seen the part, none of us can give you anything like a real answer.

People always say they understand that, but still want mail order part pricing. $160 buys you 2-3 hours of machine time, at best.

I don't machine anything for anyone but myself anymore because of this. My cost to machine custom components (as stated above already) is higher than the selling price from large retailers.

Amen, brother; the one that had me swear off trying to do work for the general public was finding out that the custom goat milking stand that I had no quoted because my cost for the materials alone was more than the price for the same thing from TSC was being used against me. The guy brought the actual TSC catalog to show me what he wanted, so I when I told him that he was less than happy....

It's probably a good thing that I've lived here almost all my life, and I still have some other farmers & small businesses in the area; his attempt at using his religious background to slander me for not giving him what he wanted cost him much more dearly than it cost me, and it still cost me way more than I would have thought being honest ever would...

I see.

Vlad, heres an answer for both of the above...

Quote #1 from above; the Tony Stark workshop does not exist. For the record, CAD stands for Computer AIDED Design; not Computer Automated Design. The same goes for CAM; not Computer Automated Machining, Computer Aided Machining.

Quote #2; theoretically solvable and reality have this really big issue of not agreeing with each other on a regular basis. The current score? Lets just say that reality is so far ahead that it isn't worth trying to even keep score any more.....

In one of your other threads, I asked you where you were in relation to Grand Rapids MI; I'll repeat the basics here. I've still got some equipment, and if all you need is a couple of saw cuts, maybe some holes drilled, I might be able to help you out. PM me.

You have to look in your area or where ever, that has a wire edm or water jet...

I think Jim was just saying off hand as an easy place to start.

And like wise what exactly is the part required. post a pic or sketch..
