Question on CNC Cutting

[Classic Finn]

I was wondering as to what computer format CNC cutters use to set up for cutting... and how easily can the data be taken from full actual paper plans?

Or what actually needs to be done to transfer these plans to the computer so its actually ready to cut?

What make the difference? Talent of the operator. My guy took all the demensions and input them first; Heighth, width, frame size, wheel position, etc. Then he put in the curve patterns which can be tweeked to what you think looks best. Then he determines how he wants to cut them out of what plywood. You need to determine if you want the patterns of the wood grain to match (if it's going to take more than one sheet per side). If it will only need a 4X8 sheet of pywood, you're ready to cut. He just tells the computer to flip the pattern and cuts the other side. If two or more parts are needed to make up the side, they will join together perfectly. Good luck. Jim

There are many new software packages now days that will do a super job. You can draw it out and cut it out. The packages are quite expensive.
This is what I do! I use a drawing package that is freeware, it runs in windows 2000, I save the file as a DFX file.
Then I have a DOS program (free ware) that convents DFX or HPGL files to G code. Then I use a DOS program (free ware) that will display the G code so I can edit it. Some of the tool multi path will not convert very gracefully. Once it is edited the way I want it, I use another DOS program (free ware) that takes G code and does step and direction for my machine. Now you have to realize that my machine is home made and has a 16” by 20” table. The electronics is home designed and made. If one byes a machine it will come with software and there is a learning curve no mater which system one gets. You can bye a machine and then bye the software to run it. Take a look at Flash Cut or Supercam! Two good lower priced software packages with a fairly fast learning curves.

I work at a sign company with two cnc routers, DXF files are best but with the new program EnRoute it can accept AI or EPS formats. (That's if they have EnRoute) If you can't do either and only have it down on paper then a scanable artwork would work it would just take some more time. If you don't have that then have a drawing with height, width, and radiuses of all your parts and the person creating the file should be able to redraw it into the computer.

Hope that helps. This is what I do everyday. If you have all the measurements right now give them to me and I'll create a file for you then save it as a DXF. That's what I've been doing for the past 12 to 13 years and I'm pretty quick about it.

Hope this helps
