Huazhong University of Science and Technology successfully developed a system for adaptive NC mill machining of constant power in 1998.
Production process adopted a tool path to remove all excess materials, the system of CNC machine tool is Siemens840D, the cutting parameters actual needed optimized are spindle speed and feedrate, the network mastered mapping relation between output variables and input variables through the solution of training the network technology by using sample data, which is teaching learning neural network.
The hydraulic shell parts of aircraft engine was processed in the multi-axis CNC machine tools(DMC60H), the material is forging aluminum and the blank is forgings.Table 1 showed that processing time required of before and after cutting parameters optimized by BP neural network model of the aluminum shell structure of part of process steps.

Strain of the specific grade point is equal to strain of the material in the standard continuum mechanics method.
The difference between material strain and unit strain is called crack strain ‘’ which represents a crack opening.
