A machinist operating a drill press in 1917. The tools that a machinist is expected to be proficient with fall into broad categories: Measuring tools: The measuring tools come in several basic varieties: Comparison tools such as adjustable parallels and plain calipers, Direct reading tools such as rules, scales, and vernier calipers,
The Shopsmith is a lathe-based multi-tool that uses a single motor to perform lathe, tablesaw, sanding, and drill press functions. Variations include horizontal boring and disc sander . The original Shopsmith 10E and 10ER were invented by Dr. Hans Goldschmidt [ 1 ] of Albany, CA , in 1947; made by the Magna America Corporation in Berkeley, CA ...
For example, a workpiece may require a specific outside diameter. A lathe is a machine tool that can create that diameter by rotating a metal workpiece so that a cutting tool can cut metal away, creating a smooth, round surface matching the required diameter and surface finish. A drill can remove the metal in the shape of a cylindrical hole.
A typical planer. A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to cut the work piece. [1]
A third type also exists, a lighter, more versatile machine, called a mill-drill. The mill-drill is a close relative of the vertical mill and quite popular in light industry; and with hobbyists. A mill-drill is similar in basic configuration to a very heavy drill press, but equipped with an X-Y table and a much larger column.

This would apply to cutters on a milling machine, drill press and a number of other machine tools. This is not to be used on the lathe for turning operations, as the feed rate on a lathe is given as feed per revolution. = Where: FR = the calculated feed rate in inches per minute or mm per minute.
