Explain the difference between CNC milling and CNC turning.

• In CNC milling, the cutting tool rotates and moves along multiple axes to create complex shapes, while in CNC turning, the workpiece rotates and the cutting tool moves linearly to create cylindrical shapes.

• CNC turning is used for creating complex shapes, while CNC milling is used for cylindrical shapes.

• CNC milling and CNC turning are the same process with different names.

• In CNC milling, the workpiece rotates and the cutting tool moves linearly to create cylindrical shapes.
