This lab is filled with a variety of nice measuring tools, on large stone tables.
This is a shadow-graph type machine. It projects an enlarged shadow of complex-shaped parts, like screw threads, so that they may be measured and verified more easily.
I believe this is called a coordinate measurement machine. It touches a part on the table, and records the coordinate. In this way, it maps out a part and can compare it to a solid model of that part, or the coordinates can be converted into a solid model.
Various items used for the above machine.
