Recently titanium and nickel alloys have become pre-eminent for aeronautic and astronautic parts. Since these cutting and becomes severely demaged. It is important to control cutting tool temperature. In this paper,the control system of tool tip temperature using inverse analysis of neural network for machining these materials was developed and evaluated. The neural network between cutting conditions...
In industry, such as oil refinery industry, there may occur various kinds of safety problems for pipelines aged after its constructions. To realize preventive maintenance of pipelines, there are large needs for the diagnosis technology of gas leakage. In this study, gas leakage sounds generated from the crack of pipe is analized and tried to be used for detection of the gas leakage. Sound data for...
The detection of abnormality in a facility is vital for plant operation. The methods by cameras and sensors are traditionally used but not sufficient for abnormal detection in the early stage. On the other hand, human feels the change of surroundings by various sensings such as eyes, noses, and ears. The diagnosis by the sound has the advantage of being able to detect the wide-ranging abnormalities...
