Hi people. I know that exist companies that make sand moulds by machining. The most common method is to use a robot. To see that please explore the link below:

The question is: how is the programming of the robot? Is like a CNC programming? The code type is like ISO CNC code?
Is possible to program using CAD-CAM automatic programming?
Can I help me with that?
Hi Daniel Martinez Krahmer,
Yes, the programming of the robots is very similar to the CNC programming of any other machining operation, but will depends on degree of freedom (or how many axes has the robot-arm) and also on the degree of complexity of shape of sand moulds.
Regarding the NC code: Yes, the control program is very similar to those, used for CNC lathe or milling or other CNC machines, but which exact G or M codes for what actions will be used in particular case, depends on the decisions of the manufacturer, the particular model and type of control /driving system of the robot itself.
On your third question the answer again is: Yes. You can use appropriate CAD-CAM (or only CAM software, if you already have CAD models of the mold parts). For example CAM software like: PowerMill (Autodesk), NX (Siemens), CATIA (Dassault Systemes), and many more other, have abilities to generate 5-axis tool-paths for machining complex surfaces. Usually the main issue here Is the presence (or not) of a working and properly configured post-processor, for correct "translation" the calculated by CAM tool-paths into a corresponding NC-code, appropriate to the particular physical robot model which will be used in the real processing of the mold parts. If you do not have such a post-processor you will obtain only "good looking" CAM virtual simulation of the machining operations.
Some manufacturers provide their robots with their own CAM software, that directly generates the corresponding NC-code. As I said it all depends on the specific case of particular robot selection.
Best regards!
