Abstract. A review of experimental data on the time dependence of luminescent decay in solids shows very few examples of the classically expected exponential dependence and none of the bimolecular law. The prevailing long-term time dependence obeys power laws in time with exponents between -1 and -2. A new approach to modeling of loss separation in grain Jan 01, 2003 · The aim of experimental verification was to introduce the cutting angle as the only changing parameter into the measured total loss dependencies. The energy losses were obtained in frequency range of 2070 Hz and maximum induction B m =1.2 T for various stacking of laminations.

of cutting forces under various cutting conditions, based on experimental data, and the prediction of the dynamic behaviour of machine tools, also based on experimentally collected data. These experimental data are used in the CutPro software, in order to predict chatter vibration free cutting Constitutive Equations for Large Deformation, Rate experimental phase of this research. Experimental verification is provided for the bending of a thick plate. Creep and relaxation behavior of the introduce a time dependence of the states of stress and strain. The plastic properties, on the other hand, make these states depend on the

Analytical Eion of T-vc dependence in standard ISO 3685 for cutting ceramic, Key Engineering EFFECT OF CLAMPING PRESSURE ON PARTS The submitted article is focused on experimental verification of clamping pressure influence on roundness deviation. Experimental parts were clamped into three bites chuck (Fig. 3) with clamping pressure value of 3,2 MPa and inner cylindrical surface was machined. Figure 3 Principle of clamping Cylindrical workpieces were made of a low carbon
plunge cutting. A key result is the spindle speed dependent stability limit that leads to stability lobes . These lobes allow for greater material removal while maintaining the stability of the process at specific spindle speeds. However, there is little published experimental data to support this theory. Many researchers have opted not to Experimental Observation of Hydrodynamics of Melt experimental verification. Visualisation of hydrodynamics on kerfs is a powerful experimental way to investigate the physical mechanisms of striation generation. Yudin et al observed striation generation process on a kerf side laterally through a glass sheet . They utilised as samples rose alloy, which has much lower melting temperature
Dec 13, 2013 · Results are presented for experimental verification of engineering system instability development during turning polymer material workpieces. The nature of the correlation between cutting regime, form of previous workpiece preparation, and turned machined surface roughness, is established.

Mar 04, 2003 · In any cutting processes, the temperature distribution in the cutting tool is intrinsically three-dimensional and very steep temperature gradient can be generated in the vicinity of the tool-chip interface. In this region, where the maximum temperature occurs, the effect of temperature dependent thermal properties may become important. OPTIMIZATION OF CUTTING CONDITIONS FOR contribution and there are no significant influences of the cutting speed and the depth of cut. The experimental verification test was compared with the results of optimal turning parameters obtained with different optimization approaches, Table 2. That obtained prediction model (2) is the very good
1 day ago · It can be considered that the generated cracks do not touch the target surface in the process of ductile-brittle coupled cutting and are removed along with the chips achieving the machining results similar to metal cutting.
