(5) Design to improve maintenance efficiency. Try to use components or components that can be quickly assembled and disassembled; perform proper structural design so that no parts or components are removed or removed when repairing a part.
(6) Perform error proof design. Misuse and misuse may occur from the design.
(7) Perform ergonomic design. Ensure adequate maintenance space during maintenance, with sufficient brightness, low vibration and noise.
(8) Design the maintainability of the software. It is convenient to recover and modify lost programs and data.
(9) Conduct a diagnostic design. Set up various diagnostic programs to prevent the occurrence and expansion of faults. After the fault is issued, the type and location of the fault can be quickly identified.
(10) Design the monitoring function. It can monitor the status of the CNC system and alarm the abnormality of the CNC system to provide information for fault diagnosis.
For example, in the GICC system, a reset function is designed to improve maintainability. In the event of a downtime caused by an interrupted operation due to program and data processing, the reset button can be pressed to put the control system into a normal working state. This will not destroy the software and normal interrogation results.
3 Conclusion
The generalized reliability growth in the development of numerical control systems is not only the reliability growth but also the maintenance improvement. The growth of generalized reliability should be achieved by the most economical means.

Disposable serological pipettes with polyester fiber plugs are ideal for tissue culture applications. Crisp, black, highly legible permanent graduations prevent ambiguity and guarantee precise reading and accurate dispensing within ± 2%. Reverse graduations show volume removed or remaining on all pipettes larger than 1mL. Generous negative graduations provide additional pipetting volume. Yongyue's serological pipettes are made from transparent USP Class VI polystyrene sterilized by gamma irradiation. Each lot is free from pyrogens, DNases, and RNases.Yongyue's plastic serological pipettes are produced under the strictest protocols and offer the highest degree of accuracy.
The pipettes are supplied with an aerosol barrier plug that prevents both liquid and aerosols from contaminating the pipettors.
The serological pipettes are produced from crystal clear polystyrene (PS) and are color coded for easy volume identification. Available in 1mL, 2mL, 5mL, 10mL, 25mL and 50mL sizes.
In addition each Pipette now features:
Crisp and bold easy-to-read graduation marks
Reverse graduations on all volumes
Negative graduations on all volumes
1, 2 and 5mL pipettes feature one-piece construction
10, 25 and 50mL pipettes feature three-piece construction
