I beileve that Goblins and Orcs are one in the same. Goblin maybe referred to smaller orcs. They is a good description of Goblins and Orcs in
The Encyclopedia of Arda.
In the forward of The Hobbit it states:

Orc is not an English word. It occurs in one or two places but is usually translated goblin(or hobgoblin for the larger kinds). Orc is the hobbit's form of the name given at the time to these creatures, and is not connected at all with our orc, ork, applied to sea-animals of dolphin-kind.
