As the speed of a handpiece increases, its torque subsequently decreases (slow-speed handpieces have high torque, whereas high-speed handpieces, like the air turbine system, have a low torque) The free running speed of 1:5 gear ratio electric handpiece is the same as its cutting speed; thus, 40,000 motor speed x 5 = 200,000 rpm burr speed.
A lack of standardization and training in both aircraft maintenance and flight operations was cited as a causal factor in a large percentage of mishaps. Several standardization programs were initiated in the late 1950s and early 1960s to counter this problem. The first was the Naval Aviation Maintenance Program (NAMP) in 1959.
The system has been in operation since December 31, 2003. It serves as the primary management tool for the reliability of transmission facilities throughout the organization's footprint. The State Estimator is one of the world's largest computer systems and provides 303,800 data points that are updated every 5 seconds. [16]
Condition monitoring techniques are normally used on rotating equipment, auxiliary systems and other machinery like belt-driven equipment, (compressors, pumps, electric motors, internal combustion engines, presses), while periodic inspection using non-destructive testing (NDT) techniques and fit for service (FFS) [1] evaluation are used for ...

An intelligent maintenance system is a system that uses data analysis and decision support tools to predict and prevent the potential failure of machines. The recent advancement in information technology , computers, and electronics have facilitated the design and implementation of such systems.
The marine and air transportation, [9] offshore structures, [10] industrial plant and facility management industries depend on maintenance, repair and overhaul (MRO) including scheduled or preventive paint maintenance programmes to maintain and restore coatings applied to steel in environments subject to attack from erosion, corrosion and environmental pollution.
Predictive maintenance evaluates the condition of equipment by performing periodic (offline) or continuous (online) equipment condition monitoring.The ultimate goal of the approach is to perform maintenance at a scheduled point in time when the maintenance activity is most cost-effective and before the equipment loses performance within a threshold.
