automatic robot spray painting based CAD/CAM

[Anonymous]

Hi guys,

I am doing a project on the theme of CAD-based automatic robot spray painting. I need to transfer the CAD data directly to robot control, so that the robot can directly painting without complicated robot programming. The details is that, how to get the profile of the object and transfer to robot trajectory, furthermore, how to extract the color from the object and transfer to robot control or painting gun system. 

I am so grateful for any ideas

That's so vague, all your going to get here are ideas:

1.  Is the spray path 2d or 3d?

1.a  If 2D then you need a region boundary to follow/stay within

1.b  If 3D then you will likely want the 3D face and then is boundary and normal (which will tell you what angle to spay at).

2. Color can come directly from the material/appearance assigned to the 3D part.

3. Do you need to break down a region into a scanning zone of paths that overlap just right for the robot to follow?

4. Perhaps look into the 3D printing output data from Inventor or the HSM/CNC output data to see if you can piggy back off of everybody else's already existing work.

Hi, thank you for helpful ideas. It's a 3D spray paths. You mean I can break down the whole face of the profile to pieces and get the boundary and normal of each pieces with Inventor,which point 3 also means ? Furthermore, I am not sure how to get the color of each pieces from CAD file and transfer to robot program so it knows where to paint the right color.

Well for sure I know Inventor, but your robot is all on you!  Parts (have a overall material property) are made of solid bodies that each have a material property.  There's your color.  It can get messy if they use a lot of material overrides, because you can override at the face level, the body level and the part level.  Better study the PartDocument.ComponentDefinition portion of the API help docs.
