Among the various reinforced materials used for aluminium, B4C has outperformed all others in terms of hardening effect.
It is also one of the most important methods to machine hard materials.
The materials were in the form of 10-mm-thick plates.
Usually, hardening of materials lowers their machinability.

Germanium is an anisotropic material.
With the development of science and technology, aspheric lens are demanded increasingly and difficult to use the traditional processing methods for processing.
Conclusion The theoretically calculation of size and fluctuation range of the germanium crystal cutting force and radial cutting force are presented in this paper ,which are calculated on different crystal planes and different crystallographic orientation and unlike isotropic metal materials.
