This was my first good crash. I wanted to flip my part over and do a chamfer on the back side. Instead of writing a whole new program just for a chamfer, I got the wise idea to use the same program that had about four ops in it and just tell the NC to run from that section of code that had the chamfer in it. Everything was fine until the mill was about to start the run and I saw the quill drop a lot lower than I was expecting and ended up landing the tool holder on the edge of the aluminum and rubbing about 1/8" of material off the edge before I could get the Estop to shut everything down. I wondered what in the world happened, and then I realized that I had named the op that used a 3/8" end mill (2D Contour) while also having the 1/4" chamfer mill that did the edge work (2D Contour)... They both happened to be about the same amount of lines of code too.
