Sir,
Do you intend to construct the entire machine from the available steel, gas fittings, bearings, gear rack, etc etc in your country? Will your machines be for production (heavy duty) or for occasional use? I could email you pictures of machines that I designed, and from these you can get design ideas. Our machines were for industrial and light industrial use.
As to the plasma and gas and drive systems, likely you will be buying the plasma, gas torches, regulators etc. You can either buy the machine drives/controls, or do your own design if you have the knowledge. If you buy others systems, you will still have to handle the actual drive mounting, gear rack choosing, and other drive associated problems.
For CNC's, you can purchase a controller such as Burny or another. Or you can use a PC and purchase a controller software such as Mach3 or others. Using software and a PC is more economical, but will require that you have quite a bit of ability in the interfacing of it.
There's quite a bit to it; I spent several years in the business and we made machines from 3 ft x 3 ft up to 14 ft wide by very long.
If I can be of help, I'll try. More specific details about what you want to do are needed.
Regards,
Jack C.
