Common machine tool operations.
Turning rotates the workpiece against a single-point tool on a lathe; milling rotates a multi-tooth cutter against a workpiece (face, end, peripheral); drilling makes holes with twist drills; also boring, reaming, tapping. Select cutters, speeds and feeds from tool catalogues.
A 10 mm drill at 30 m/min runs at about 955 rpm.
Turning, milling and drilling are the basic machine tool operations that make most mechanical parts.

Turning, milling and drilling are the basic machine tool operations that make most mechanical parts.
It rotates the workpiece while a single point tool removes material, which suits round and cylindrical parts.
It rotates a multi-tooth cutter against a workpiece, which removes material to make flat faces, slots and complex shapes.
Typical applications include turning a bearing journal on a lathe, cutting slots and profiles on a milling machine and making a pilot hole for a threaded fastener on a drill press.
Study "Machining fundamentals" first (topic 19 of 102 in Manufacturing, Robotics & Systems). It covers the groundwork this topic builds on.
Spindle speed N=1000v/πD. Climb vs conventional milling. Peck drilling.

The next topic is "Grinding and finishing", which builds directly on this one.
It is classed as Beginner in Manufacturing, Robotics & Systems (topic 20 of 102). It is an entry-level topic. It relies only on basic school mathematics and the ideas introduced earlier in this discipline.
