CNC milling and solidworks

For my graduating project on school I have a scale model
(size=shoebox) cnc mill without any kind of steering at all. Now I
want to make new communication, but I don't know where to start. We
use solidworks for drawing. Is it possible to make software that can
read simply parts (solidworks), and then generates G-codes (only G00,
G01, G02, G03)? I know that there are many packages on the market
which can do this but there isn't budget for it.
Is there someone who can help me any further with this?

Thank you very much,

Rik

 

Rik,

Do you mean you want to write a CAM program ? or that you want one for free
?

Any CAM program that can read SW or parasolid 3D data is gonna cost some
serious money.

You could maybe get a free DXF to G-code program. This would require out
putting a 2D SW drawing to DXF. Do a Google search in "alt.machines.cnc" for
"DXF to G-code"

Regards

Mark

There's nothing that will simply output a G-code file from a model (it's
not like converting a SW model to IGES).

There's a lot of work involved in machining a part. Setups, tool sizes,
operations, blah blah blah. It requires complex software to manage that
process. Complex software = $$$.

Sorry.
