3.1 CNC lathe

The main motion is the rotation of the workpiece relative to the tool, and the cutting energy is a CNC machine tool provided by the workpiece instead of the tool.

Note: This type of CNC machine tool is automatically provided by a digital control unit. [GB/T 6477-2008, definition 3.1.1]

3.2 Failure

The ability of the product to complete the required function is interrupted.

Note 1. After failure, the product is in a fault state.

Note 2. The difference between "failure" and "fault" is that the failure is an event and the failure is a state.
