This is an “easy” way to locate a CNC milling machine spindle over the edge of a metal part to an accuracy of 2/10,000 inch (.0002″).
Two cameras were used to see two views at once.
I require my high school students to perform this skill to an accuracy of 2/10,000 inch (.0002″) within a 2-minute time limit.
(I own the copyright of this video because I wrote the description, narrated it, and demonstrated this skill.)
