Polycrystalline Cubic Boron Nitride

Ti-6Al-4V components are the most widely used titanium alloy products not only in the aerospace industry, but also for bio-medical applications. The machine-ability of titanium alloys is impaired by their high temperature chemical reactivity, low thermal conductivity and low modulus of elasticity. Polycrystalline cubic boron nitride represents a substitute tool material for turning titanium alloys due to its high hardness, wear resistance, thermal stability and hot red hardness. For determination of suitable cutting parameters in dry turning Ti-6AL-4V alloy by Polycrystalline cubic boron nitride cutting tools, the samples, 300mm in length and 100mm in diameter, were dry machined in a lathe. The turning suitable parameters, such as cutting speed, feed rate and cut depth were determined according to workpieces surface roughness and tools flank wear based on orthogonal experimental design. The experiment showed that the cutting speed in the range of 160~180 m/min, the feed rate is 0.15 mm/rev and the depth of cut is 0.20mm, ideal workpiece surface roughness and little cutting tools flank wear can be obtained.

In order to increase the accurate finishing productivity of pearlitic cast iron, face milling by CBN (Cubic Boron Nitride) cutting tools was studied. The main focus of the study is the machinability investigation of pearlitic cast iron with CBN cutting tools by studying the relationships among machining conditions such as feed rate, cutting speed as well as CBN cutting tool type, tool wear, workpiece surface quality, cutting forces, and cutting temperature. In addition, an emphasis is put on the effect of Al additive in pearlitic cast iron on its machinability and tool wear characteristics. High-speed milling experiments with CBN cutting tools were conducted on a vertical machining center under different machining conditions. The results obtained provide a useful understanding of milling performance by CBN cutting tools.

Abstract Diamond and cubic boron nitride (cBN) cutting segments were produced using hot pressing technique for this study to be used in cutting natural stone. cBN grains were added to bronze powder, the chosen matrix, at a rate of 0%, 20%, 40%, 60%, 80%, and 100% (according to percentage by weight). Segments were produced under a pressure of 35 MPa, at a sintering temperature of 600°C, over a sintering time of 3 minutes. The cutting properties of the produced segments were determined by cutting Ankara andesite. A Scanning Electron Microscope (SEM) and an X-Ray Diffractometer (XRD) were used to analyse the microstructure, phase compound, and wear surfaces of each segment type.

Cutting Velocity

Micro-textured cutting tools were widely reported due to the improved cutting performance, for example, the reduction of cutting forces. However, the cutting performance is significantly dependent on the parameters of the micro-textures. In this work, some polycrystalline cubic boron nitride tools with designed circular micro-textures were designed and manufactured by laser processing technology, and used to machine powder metallurgy materials. The effect of micro-texture parameters (diameter, depth and density) on the cutting forces ( FX, FY, FZ and Fr) was studied by an orthogonal test, the effect of cutting velocity on the cutting force was also studied. The results have shown that the pit diameter and depth have more significant effect on the cutting forces than the cutting velocity and pit density. As compared with the non-textured tools, the textured tools can effectively reduce the cutting forces and the optimal cutting forces were achieved at parameters as 230 μm for diameter, 90 μm for depth, 20% for density and 110 m/min for cutting velocity. The present findings are of significance for the design of polycrystalline cubic boron nitride cutting tools and the processing of powder metallurgy materials.
