Turning machining is cutting metal into shapes. Lathes are used for turning. A lathe spins the metal fast. The tool cuts the metal. Speed can be 1200 RPM. Depth of cut is 0.1 mm.
Cutting tools are HSS or carbide. Lathe beds hold everything steady. CNC lathes use computers to guide. G-code tells the CNC lathe what to do. Chuck holds metal. Coolant keeps the tool cool. Chips are tiny bits cut off.
