The system consists of five function modules: machining error propagation modeling module, machining error propagation analysis module, data acquisition module, quality monitoring and analysis module, error source diagnosis and adjustment module.
Data Acquisition Module.
It is used to gain real-time quality data on character parameters and working condition from key machining elements, and provides indispensable data for quality monitoring and improvement.
The forth step is to establish the fuzzy corelation model between equipment parameters and abnormal pattern of quality data by conducting knowledge reduction of abnormal pattern and equipment failure.
On this basis, the error source can be explored when quality data is out of tolerance or abnormal pattern occurs.

The presence of this uncertainty will inevitably lead to a reduction of the accuracy of monitoring and fault diagnosis, and even lead to missed and mistaken diagnosis.
The structure model of MIF is often divided by the level and integration position of the data processing.
According to the level of data processing, the structure model of MIF is often divided into three-layer fusion structures (the data layer, feature level and decision-making layer).
Industrial processes Information for decision-making Feature information Data information Recognition detect Decisio–making System (database / blackboard system) Multi-sensor networks Image information knowledge of the domain Data layer fusion Feature layer Fusion Decision– making layer fusion Signal level fusion Pixel level fusion Feature Extraction Symbol level fusion Multi-sen- sor manage- ment and resource allocation Fig.3 The structure of the industrial monitoring system Figure 3 shows that the information fusion of the system is divided into three types (data layer fusion, feature level fusion and decision-level fusion).
The diagnosis knowledge includes a variety of prior knowledge, such as rule-based knowledge and fault tree-based model knowledge and so on, and it also includes the new knowledge on the state of the object getting through data mining, such as rules, classification and so on.

Damping loss factor at each natural frequency could be determined from measured vibration data by some signal processing.
Experimental results showed close correlation with the calculated data.
Figure 5 shows stress history at the selected position compared with calculated data.
Under the static load condition, experimental results showed similar level of stress with the calculated data.
Close correlation between experimental results and calculated data showed that calculated data is good enough to predict the response of the system under static and vibration load.

Fig.4 System response at low speed neural network resistance observer 1 neural networks training data In this paper, neural network resistance observer have a data collection in different input current (i), different stator frequency(f) and consecutive time(t∈[0,140]min).
When Motor works in Figure.5 currents and frequencies, measuring one time every 10 minutes, the data is shown in Figure.6.
Fig.5 condition of experiment Fig.6 The actual waveform of △R prepare training data, namely input and output data.
create a network object train network input the new data, then Access network response.
Then the network trained by teacher has "learn" the knowledge and rules of training data, so it can be used for the job.

One of its main selling arguments is the possibility of substantial reductions on the total cost of ownership of IT infrastructures.
Finally data tier is important factor to store and manage all of the cloud computing resources data.
It can be include memory capability in cloud computing server, distributed file system, and key-value data for cloud computing resources.
The architecture has 3 tiers; presentation tier, business tier, and data tier.
And data tier is most important factor and handle the management of data store and process such as cloud computing resources data, cloud application data, user data for cloud computing use.
