This week I have been learning how to manually set the CNC milling machine and run a pre-designed program. This was surprisingly similar to the manual milling. I expected the machine to have an internal detection system that could set the machine to the workpiece. But instead, many of the functions were similar to manual milling, such as finding the zero with the wobble bar and setting the vice square with a DTI (Dial Test Indicator).
Another interesting change was how the machine could hold all the required tools and how you had to set the tools in accordance with the program. It was quite tense when I set the machine running for the first time since, but luckily I completed the piece without breaking any tools.
