Thread: CNC pricing for project

Hello chradlapm

If you go to a CNC company then you will be paying top dollar for your requirements. They are a business and they need to make a proper profit.

I suggest that you ask on this board for someone in your area who has the required capacity and machine to make what you need. It will likely come in at a MUCH lower price because we are usually just trying to make our hobbly pay for itself.

OK thanks for that Bob. I dont know much about CNC equipment so I really did not know where to start. I would rather have someone in my area or at least someone who can do it give a price for there time then. Should i start another thread or how do I go about finding others in my area who have a CNC?

Just dont want to seem "shady," or a guy who is only becoming a friend just to use someone. Is a search area, stalking, to find others with CNC machines?

Thanks for your time.

And lastly what is it called when a CNC can do different angles? IS that a 3d or 5d..... confused. I originally thought I could have one person do the cutting for me and then I would assemble the pieces at home. But then I realized that not all machines can do different angles.(Not 90 degree cuts) SO I was then figured I could at least get the harder cuts done that are only 90 degree cuts and I will do the rest. It would be a big help for me either way.

This project does not have to be CNC I just was hoping it could be done for my building skills are not the greatest and I would like it to look very professional.

Thanks again.

There is or at least was an Adelaide CNC user group, they were having regular scheduled meetings at one stage, I don't know if they are still doing so but it would be worth a shot.

I haven't seen anything here but if you do a search for adelaide over in cnczone you will find some old threads, try sending a PM to one or two of the organisers and see how you go.

As Bob mentioned a commercial shop will charge heavily for a one off, time is money and all that, but if you find somebody that has a machine big enough and is willing to help then you will be surprised how far a carton of beer will get you (so long as it is cold beer !)

Do you have drawings ready to go ? Usually a CAD format set of plans is the starting point for getting somebody to cut anything out.

Good luck

Russell.

I have a PDF file that describes all the cuts needed to be done. I can also get a CAD file if needed. I will try and look for the old threads. That would be most helpful if I could find them.

What do you mean by "describes" all the cuts?
Is it a PDF picture of the actual item with measurements on it or what?

Yes it has a picture of the cut piece with all measurements and angles. I can get a Cad drawing also or cad file depending on what machine they use.

Most of the people here would probably need a DXF of the items. from that, they would be able to generate the Gcode ofr cutting the items with a minimum of trouble.
Is there anything particularly difficult about the items? Are you willing to post a jpg of what you want so that we can get a better idea of your needs?

I do not know how to make a Jpeg from the adobe file I have for the build. But I will try and get the DXF file.

I exceed the file size. The DXF file I have for a similar build is 1.5mb and I can only upload 244kbs. And both of the builds I want to do are in pdf files that are 10mb and 19mb files.

Here is a photo that is small enough for me to upload. I was able to convert the DXF file to Jpeg and I did the PDF file to Jpeg also.Thanks for that.

Here are some Jpegs. These are in imperial measurements also. The material used is 3/4(18mm) plywood. I was going to be using Marine grade ply from Bunnings because its the cheapest ply I can find that is void free. $120 a sheet.12x2400(8x4)

You don't need a CNC for that - you just need a router and a straightedge. If you were making thousands of them, or there were lots and lots of precise cuts then it'd be worth CNC'ing it, but as it is you'll be paying a fortune in setup costs for a few minutes cutting.

$60 will get you an ozito router from bunnings, and add $20 for a set of cheap bits and $20 for eye/ear protection.

Note that you will have to be precise with your imperial to metric conversions - 3/4 inch is actually 19.05mm, so your ply will be 19mm, not 18mm - make sure you check the thickness with a calliper rather than relying on what is printed on the shelf!

I hear what your saying but there are quite a few pieces and others I know are just having a CNC company cut the pieces out. Then assemble themselves. I could cut everything myself but wondered what it would cost for a CNC. I am always busy and if I have to save up so that I can build these cabinets in a time manner then I will do that. Four children and a never ending list of things to do makes time short most of the time.

Either way thanks again for your help.
