3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Reliability reliability
CNC system under specified conditions and within the specified time interval to complete the required function capability.
NOTE. rewrite GB/T 2900.13-2008, defined 191-02-06. CNC system is generally considered the beginning of the time interval is required to complete the function of shape
state. In addition, although the magnitude of reliability objectively exist, but in fact is unknown, we can only use a limited sample observation data, after a certain
Statistics calculated its estimated value. Reliability is also known as the magnitude of the reliability.
3.2
Reliability Design reliabilitydesign
The use of methods to achieve specific design practices or procedures CNC system reliability goals.
3.3
The average time between failures meanoperatingtimebetweenfailures; MTBF
Adjacent fault mathematical expectation of working hours, but also refers to the average working time between two adjacent failures or MTBF.
NOTE. rewrite GB/T 2900.13-2008, defined 191-12-09.
3.4
Life sectional lifeprofile
CNC system from manufacturing to end of life, or opt out of sequence during this time experienced the full description of the event and the environment. NC Department
Event systems generally have experienced R & D, production, inspection, testing, packaging, transportation, storage, assembly (mounting), commissioning, operation (use), failure to stop
Release, maintenance (maintenance), retirement and the like. CNC system environment may have experienced vibration, shock, electromagnetic interference, heat, cold, humidity (water spray), sand
Dust (sand and dust), salt spray and the like.
3.5
Mission profile missionprofile
Timing is described in the numerical control system complete the required tasks during this time experienced the events and the environment.
