Abstract This study presents an investigation of the usability and suitability natural rocks as cutting tool materials. Therefore, indexable inserts are manufactured from eight different two mono minerals in this used for turning aluminium alloy. Besides that, a characterization rock properties is performed. The wear tools surface roughness workpiece generated by to evaluate their operational b...

The major needs in machining are high material removal rate, good work surface finish and low tool wear. These objectives can be achieved by reducing tool wear using proper cutting fluid during machining.The effect of some cutting fluids namely: Mentholated spirit, paraffin, and soluble oil on the flank wear of High-speed steel and carbide tipped tools by orthogonal cutting has been studied. Ce...

High speed machining (HSM) may produces parts with substantially higher fatigue strength; increased subsurface micro-hardness and plastic deformation, mostly due to the ploughing of the round cutting tool edge associated with induced stresses, and can have far more superior surface properties than surfaces generated by grinding and polishing. Cutting edge roundness may induce stress and tempera...

The reliability of cutting tools is critical to machining precision and production efficiency. The conventional statistic-based reliability assessment method aims at providing a general and overall estimation of reliability for a large population of identical units under given and fixed conditions. However, it has limited effectiveness in depicting the operational characteristics of a cutting t...

An on-going comparative study of wear rates and tool lives under varying cutting parameters is presented in this paper, along with results indicating the abilities and limitations of the hard turning process to produce finished surfaces with acceptable roughness and integrity. To date, the study has consisted of thirteen combinations of machining conditions. The tests were performed with four d...

Hardened steels are commonly used in wide areas of technologies and industries. In respect of poor machinability of these steels and requirement of expensive cutting tools, study of machining economy is a matter of importance. Thus the present study deals with the economic considerations of various hole making processes. For this purpose, the hard steel samples were machined by conventional dri...
