With new materials of workpiece and cutter emerge; new experimental data is required to meet the demand of the production.
Xu Mingsan [9, 10] conducted experiment to study the cutting force based on different materials and cutters.
In the modification equation of main turning force, the influencing factors include 9 terms such as workpiece materials and the output is modification coefficient K.
So, when designing neural network, workpiece materials are as independent input and there are 9 network inputs as shown in Fig. 3.

Incoherent scattering is a type of interaction that occurs when the radiation penetrates through certain materials.
According to the relation between the density of the material and the electron density, the radiation scattering method is applicable to be used in the investigation of the material density.
