I remember well the first time I witnessed a CNC routing machine cutting out parts. It was pure magic! Yesterday I saw a CNC plasma cutter in operation for the first time. Better yet it was cutting out some steel for a project I had long been waiting for. With seemingly no effort it cut through half inch steel like butter. The 4' x 8' sheet was so heavy we needed a forklift to load it onto the table. In only a few minutes it reduced the entire sheet to small pieces of dinosaur shaped bones. It was pure MAGIC!
Here's 25 seconds of the process for your viewing pleasure...
