Yes, but not only once. In "Revenge of the Sith," Obi-Wan defeated the duel against Vader by cutting off both of his legs and his left arm. And in "Return of the Jedi," Vader got his right hand cut off because Luke Skywalker was giving into anger and he was dueling Vader within his rage. When Vader was originally Anakin Skywalker in "Attack of the Clones," Anakin lost his right arm during a duel with Count Dooku on Geonosis.
Yes. In Episode 2: Attack of the Clones, while in a lightsaber duel with Count Dooku, Anakin lost his right arm to Dooku's lightsaber and had to be replaced with a cybernetic prosthetic

Darth Vader
The empourer was off guard and was nearly beat by mace window who was not as skilled a darth vader
Luke is resisting giving in to the Dark Side, so Darth Vader is fighting Luke with his light saber, and cuts off Luke's hand to show him his power, and to even further persuade him in joining him (Darth Vader) on the Dark Side. This act of cutting someone's hand off is called Cho Mai according to Jedi records. This is considered merciful by most Sith Lords who prefer killing their opponent.

When faced with either finishing off Darth Vader of running after Emperor Palpatine, jump down to Darth Vader for a final fight.
Definately Harry Potter! Darth Vader would slice off my arms, Harry would just get it done!
Darth Vader has beaten him in Empire Strikes back and it would take him 6 minutes to beat him since Luke sees how the force works. But it eventually got to the part where Vader cut his hand off. Darth Vader would win.
That is a matter of opinion but I would say no, as Darth Vader can reflect energy blasts with his light saber, divert missiles and bombs with the force and of course; force choke her before she can get a move off.
