The complete or partial loss of specified functions of a CNC machine tool is called a malfunction of the CNC machine tool.
The failure rate of CNC machine tools varies significantly over time. Due to the shape of the typical failure curve resembling a bathtub, it is called a bathtub curve or machine tool failure rate curve, which is divided into three stages. The first stage is the initial operating zone, with a negative exponential curve and a high machine failure rate. The last stage is the effective life zone of the system. Generally, CNC machine tools can only enter the effective life zone after running for 9-14 months, so the warranty period for CNC machine tools is around 1 year. Entering the effective life zone, machine tools have a very low failure rate; The IQ stage is the aging zone of CNC machine tools, during which the system's failure rate increases sharply with time. This curve helps us understand and analyze the occurrence of faults in CNC machine tools.
Numerical control machine tools are products of mechatronics integration, with complex structures. The faults of CNC machine tools are also diverse, and the causes of faults are generally complex, which brings many difficulties to the fault diagnosis and maintenance of CNC machine tools. In order to facilitate the analysis and diagnosis of machine tool faults, this section roughly divides the faults of CNC machine tools into several categories based on factors such as the nature of the fault, the cause of the fault, and the location of the fault.
