SME (the Society of Manufacturing Engineers) has a great playlist of Youtube videos that outlines many basic manufacturing processes, and they are all right here for you. Most of the videos are from two to five minutes in length, and get the main points of those processes across to students in an easy to understand format. There are 44 videos in all. Thanks SME!
