What are systematic and random faults in precision parts processing

In the process of precision parts processing, the CNC machine tool fails and loses the specified function. According to the inevitability and contingency of the failure, it can be divided into systematic failure and random failure.

Systematic faults refer to faults that occur in machine tools or CNC systems as long as certain conditions are met. For example, in the process of precision parts processing, if the network voltage of the machine tool is too high or too low, the system will produce a voltage high alarm or a voltage low alarm; If the cutting amount is not arranged properly, overload alarms will be generated.

Random faults refer to faults that only occasionally occur once or twice under the same conditions. It is not easy to artificially cause the same malfunction to occur again, and sometimes it is difficult to encounter it again for a long time. The diagnosis and troubleshooting of such faults are very difficult. In general, these types of faults are often related to local looseness and misalignment of mechanical structures, drift in the working characteristics of some components in CNC systems, and a decrease in the reliability of machine tool electrical components.
