As the mechanical scratching of diffraction gratings still depends on the experiences of operators
it gives poor grooved quality and can not be precontrolled. This paper proposes a diffraction grating production method: film classification test engraving method based on an aluminum thin film deposition process status quo
and reveals the microstructure and mechanical properties of different thin film samples based on Xray Diffraction(XRD)
Scanning Electron Microscope (SEM) and nanoindentation experiments. The study results show that the grating ruling can be approximately equivalent to a wedge under the pressure of the process
so that the slipline field can be used to obtain the solution analytically and carve the slot on time trial for the low elastic modulus class film. Moreover
the finite element simulation can be used to precontrol the slot for elastoplastic class. The method can implement the preclassification of the films, and can determine the tool processing parameters for different types of films with different methods. Futhermore
a nearperfect trough is scratched. Experiments show that the timeconsuming and preengraving test times are reduced and the graving quality and efficiency are improved. The method lays the foundation for improving the characteristics of more sophisticated gratings.
