RE: [CAD_CAM_EDM_DRO] Reverse CAD CAM

I don't own the secrets, they are confidential, so my discussion is limited.

I manufacture CNC machines to blow foam surfboard blanks.

Sculpting with foam blown in open space has many problems and will not be as
easy as it sounds. It is not simply a case of pop the valve for a certain
amount of time to create a bobble of X size, skin boundaries form between
old and new surfaces and severely effect the rates of expansion. You also
have to be very careful of environmental issues regarding foam blowing.



Really think this through and do some manual tests before you spend a
fortune on a control systems and find you cannot gain an acceptable final
result.

Be very sure what you are providing will meet the customers needs, and get
the customer to accept this.

Hello. I have a client that needs a small machine to inject material
instead of removing it. Basically the machine will behave like a small
mill, but it will not take chips off, it will inject foam (I think).
The idea is to create objects in an empty space (no mold is present).
The client will provide the 3D objects, so I was wondering what are
the software that could take the 3D format (any popular format), and
output ISO gcode for the machine to handle.
Thank you from your time.

Filipe
