This chapter focuses on the purpose of using diamond as a cutting tool in various ultra-precision machining applications. The complicated structures such as resin and ceramic mold used for making optical lenses are machined by the diamond tool to improve the precision of the finished product. It is difficult to machine hard and brittle materials such as glasses, ceramics, and composites with the assistance of diamond tool due to the complexity in the aspheric surfaces. Moreover, the tool wear is a major problem in machining these hard materials to a fine dimensional accuracy and tolerances. The microscopic defect forms at the cutting edge lead to the damage of the surface finish of the workpiece material. Therefore, the discussions are associated with the achievement of machining hard materials using a diamond tool in ultra-precision applications.

Preparation of grinding wheels is the most important effective factor in glass machining. This article presents the comparison of the iron-and copper-based grinding tools. The performance of the tools is investigated based on technical and commercial aspects using same cutting speeds, feeds, and sizes of diamond grits. Scanning electron microscope is used in order to observe the microstructures of cutting tools. The service life of the grinding tools is determined on the production line in a flat glass plant. A lifetime of Fe-based diamond tools is longer compared to the copper-based wheels. The impact of metal bond materials on the service life is examined. The results show that the Fe-based tools are more economical and more useful for grinding of glass. The holding of Fe-based bonding to diamond grit is stronger than the copper-based ones.

“…[1][2][3][4][5][6][7][8][9] In this article, a systematic study on various workpiece boundary conditions ͑WBCs͒ in molecular dynamics simulation is carried out to make sure the MD analysis results are reliable in nanometric cutting. In addition, MD can conveniently change the cutting conditions, the cutting tool geometry, and the property of the work materials.…”

Articles you may be interested inSoft-spring wall based non-periodic boundary conditions for non-equilibrium molecular dynamics of dense fluidsThe molecular dynamics ͑MD͒ analysis at the nanometer scale is a powerful tool for understanding the material removal mechanism. In simulating the nanocutting process, various boundary conditions of the workpiece modeling can be applied. The influence of these workpiece boundary conditions ͑WBCs͒ to cutting results is systematically studied, including the boundary conditions of only bottom, bottom and cut-in side, bottom and cut-out side, and bottom and both side and full scale WBC or not. The results of the simulation confirm that the boundary condition of bottom and closed cut-out side is best suited to the nanometric cutting process. According to the above-mentioned results of boundary conditions, the MD simulation experiment was carried out with the undeformed chip thickness from 1 to 5 nm. It is indicated that the undeformed chip thickness has strong influence on the cutting, that is, with the deepening of cutting, cutting force becomes stronger, whereas the ratio of the normal force to tangential force becomes less. However the variation of the ratio does not vary much.
