According to the formation speed, there are gradual faults, sharp faults and sudden faults.
1. Gradual failure refers to the gradual deterioration of the functional indicators of parts and components of CNC machine tools or CNC processing equipment, but they can continue to operate.
2. Sharp failure refers to the sharp deterioration of the functions of parts and components of CNC machine tools or CNC processing equipment, which cannot continue.
3. Sudden failure refers to unlicensed. Unpredictable failure.
In addition to the above classification, faults can be divided into early faults, accidental faults and wear and tear faults in terms of time. From the perspective of use, faults can be divided into use faults and essential faults.
Faults can also be divided into catastrophic, fatal, severe and mild faults in terms of severity.
According to the process of failure, it can be divided into sudden failure and gradual failure.
According to the frequency of occurrence, there are sporadic faults and multiple faults.
According to the consequences, there are general faults, serious faults and malignant faults.
