I have been demonstrating the skills necessary to pass the CNC milling cell. I had to demonstrate the ability to prepare work on an angle plate, run a program on it, set two separate data within the same machine, and clock a datum around a circular pocket or extrusion with a DTI (dial test indicator).
Setting the angle plate was quite simple since it is an easily transferable skill from the manual milling machines. Setting the datum around a circular pocket was quite difficult because I had to spin the DTI around the pocket; this would result in the dial facing away from me so I had to use a mirror to see it, but this reversed the image so I had to interpret its readings backwards.
