Cutting thousands of these small pieces of aluminum with the help of an Arduino and a couple of stepper motors. They will eventually become brackets to fasten computer monitors to metal enclosures. Here's a quick lil vid on how I did that. The brackets measure .750" x .547" x .125", tolerance is quite decent at + or - .002"
I tried to keep the code as simple as possible because I'm not much of a programmer and didn't want to spend too much time on it. The loop is triggered by the Arduino reset button. The linear actuator is controlled by an h-bridge with 4 simple switches activated by one of the steppers.
