Abstract
This paper deals with the turned surface formation mechanism of single crystal lithium niobate (LiNbO3), which is turned by a single crystal diamond tool. In the paper, the cutting force distribution models are proposed, the three micro-cutting force components are measured, and the cutting force components normal to the cleavage planes and parallel to the slip plane are calculated. It is pointed that the ratio K of cutting force components normal to the cleavage planes to that parallel to the slip plane varies with the cutting directions, causing different levels of cleavage fracture and plastic deformation. So, the surface roughness shows anisotropical characteristic. The theoretical analysis mentioned above is verified by the experiments performed on the MSG-325 Diamond Lathe.
