The paper gives an analysis of acoustic-emission signals measured in the course of laser cutting of steels plates DC04 and X5CrNi18-10. Laser cutting is a process in which there can be a wide range of cutting parameters, but nevertheless cutting of plate products can be accomplished. Within the range of the parameters concerned, however, the quality of a cut edge can vary quite strongly; laser-...

In the present work Taguchi method is used to optimize cutting parameters during dry turning of AISI 304 austenitic stainless steel with AlTiCrN coated tool. The coating was deposited on fine-grained K-grade (ISO K-20) cemented carbide cutting insert using physical vapor deposition (PVD) technique. The turning parameters evaluated are cutting speed of 200 and 260 m/min, feed rate of 0.20 and 0....

The experimental investigations of the tool wear in turning of EN 31 alloy steel at different cutting parameters are reported in this paper. Mathematical model has been developed for flank wear using response surface methodology. This mathematical model correlates independent cutting parameters viz. cutting speed, feed rate and depth of cut with dependent parameters of flank wear. This model is...

In a time when modern production has become exposed to strict market demands, in terms of increasing quality, shortening the processing time and reducing the cost of the final product, laser processing has become a necessity in almost all manufacturing industries. Each laser manufacturer, including the Swiss company Bystronic, gives recommended cutting parameters for certain types of materials....

High speed machining of hardened steels for manufacturing dies and molds offers various advantages, but the productivity often limited by mainly tool life. This study investigates the influence of edge preparation in cubic boron nitrite (CBN) cutting tools on process parameters and tool performance by utilizing practical finite element (FE) simulations and high speed orthogonal cutting tests. T...

Optimization of cutting parameters is important to achieve high quality in the machining process, especially where more complex multiple performance optimizations are required. The present investigation focuses on the multiple performance optimizations of machining characteristics of unidirectional glass fiber reinforced plastic (UD-GFRP) composites. The cutting parameters used for the experime...

Conventional machining is a form of subtractive manufacturing, in which a collection of material-working processes utilizing power-driven machine tools are used to remove undesired material to achieve a desired geometry. This paper presents an approach for comparison between turning center and vertical machining center by optimization of cutting parameters at cylindrical workpieces leading to m...

In this study, an experimental approach is presented for the measurement of the surface roughness of the machined surface produced by simple turning operation in a computer numerically controlled (CNC) Lathe. The parameters used in the experiment were reduced to three cutting parameters, cutting speed, depth of cut, feed rate. Other parameters such as tool nose radius, workpiece length, workpie...
