Turning vs Milling Explained:The One Difference That Changes Everything

In turning, the part spins. In milling, the tool spins. That one swap changes everything: the machines, the tools, the chips, the shapes you can make, and even the marks left on the surface. In this video: How a CNC lathe works: X and Z axes, facing, turning, grooving, threading, boring and parting off Continuous vs interrupted cut, long chips and chip breakers Cutting speed (Vc = π × D × n ÷ 1000), constant surface speed (G96) and feed per revolution How a vertical machining center works: end mills, face mills, drills, taps and boring heads Climb vs conventional milling, and feed per tooth (vf = fz × z × n) Why many real parts need both: keyed shafts, hydraulic cylinders, live tooling and mill-turn machines How to tell how a part was made: shape first, then the marks Chapters 0:00 Intro 0:29 The one difference 1:22 Turning 3:55 Milling 6:14 Side by side 7:10 Many parts need both 7:55 How to tell 8:37 Outro Which process should we break down next?
