How do you get cash from a coin machine?

Excuse me, could you please explain the process of withdrawing cash from a coin machine in detail? I'm not very familiar with the mechanics behind it and would appreciate a step-by-step guide. Specifically, how do I insert my coins, select the amount I want to withdraw, and then retrieve my cash? Additionally, are there any fees associated with using a coin machine, and if so, how are they calculated? I'm also curious about the types of coins that are typically accepted by these machines. Thank you for your time and assistance.
