Hi all really hope you can help

my head is going round and round I have no idea where to start if I'm honest
I currently hand paint MDF badges for local grassroots football teams
I set up a Facebook page for people to see my work and a guy messaged me
showing me some of his work and it was amazing I asked him how he done it
he said CNC router at that point I never knew what one was
that's where it all began so I'm here to learn everything I can about build cad/cam etc
the problem I have is I have no idea what parts to get or even what there called
is there a list of basic parts on here I could read just to get me heading in the right directions?

any help would be greatly appreciated
