Abstract: On the basis of the study on the crystal structure of single crystal germanium, the relationship between the chip removal of optical crystal material and crystal orientation is fully analyzed. The optimum directions of shear slip are determined, the fly cutting method of single crystal germanium is put forward in the most favorable cutting directions. The cleavage fracture zones on the machined surface are eliminated completely with fly cutting and the homogeneous smooth surface of roughness value of 0.007 ~ 0.009μm is obtained.
