CAD/CAM research topic ideas.

Hi all,

I am a manufacturing engineer in the making (heh), and am currently taking a CAD/CAM class for school. I have an upcoming project which requires me to write a research paper over some CAD or CAM related topic.

I am interested in new processes (laser, water jet, plasma...) relating to CAD/CAM. Is there anything that is just emerging or is still in the development stage along this line?

What about unique uses for this software?

Thank you!
