Diamond Cutting Tool

Molecular dynamics is a rapidly developing field of science and has become an established tool for studying the dynamic behavior of material machining. A three-dimensional molecular dynamics (MD) model about the atoms of the diamond cutting tools and the diamond grits is built by using the molecular dynamics. The Tersoff potential function is used to calculate the force and potential energy among the atoms of the diamond tools and the atoms of the diamond grits. The lapping processes at a special cutting depth are simulated. The variety of the specimen potential energy in the lapping process is observed. The mechanism of the diamond micro machining and the form of the surface formation are given by comparing the distribution maps of atoms in initial and cutting states. This study will give a strong support to the diamond cutting tools’ lapping.

Diffractive optical elements (DOE) can be used to simplify optical systems such as lightening its mass, reducing elements numbers and so on. Single-crystal diamond is considered as the preferred tool materials in ultra-precision and nanometer-scale cutting operation. Due to the well known and exceptional difficulty in shaping, the fabrication of diamond cutting tools requires special processing method. As a highly efficient and cost-effective solution, the mechanical lapping process has been extensively applied in tool-making industry. In this paper, the key enabling technologies to design and fabricate the diamond-cutting tools for ultra-precision and submicronic machining are presented and reviewed. The paper describes the shape of micro cutting tool that is based on the finite element method of calculation of relief angle and rake angle.

Cutting Tool Materials

Some engineering materials have excellent performances, but the machining of these materials is a problem. It is very inadequate to meet machining requirement only using traditional cutting tool materials. Therefore, exploring the machinability of difficult-to-machine materials and applying appropriate cutting tool materials have drawn much attention in metal cutting industry for guarantied product quality and productivity. Cubic boron nitride (CBN) has been recognized as one of the most suitable cutting tool materials due to its high hardness, high wear resistance, high chemical inertness, and excellent chemical stability in high temperature. Research on various aspects of CBN cutting performances has been conducted in recent years. This paper presents the progress on machining difficult-to-machine materials using CBN cutting tools.
