Grinding chatter is a self-induced vibration which is unfavorable to precision machining processes. This paper proposes a forecasting method for grinding state identification based on bivarition empirical mode decomposition (BEMD) and least squares support vector machine (LSSVM), which allows the monitoring of grinding chatter over time. BEMD is a …

5-Axis CNC Lathe. In such machines, a second Turret is added to a 3-axis CNC lathe (e.g. T2-2T). Such machines would then have 2-axis at each turret (upper and lower turret) plus the C-axis on the rotating spindle. This enable the use of 2 tools at the same time on the part, hence reducing cycle times drastically.

Working Principle of Electron Beam Machining. In an electron beam machining, the electrons strike the workpiece with a high velocity. As the electron strikes the workpiece, the kinetic energy of the electron changes into heat energy. The heat energy so produced is used to melt and vaporize the materials from the w/p.

Quadrupole Analysers. The quadrupole analyser consists of a set of four parallel metal rods (Figure 1).A combination of constant and varying (radio frequency) voltages allows the transmission of a narrow band of m/z values along the axis of the rods. By varying the voltages with time it is possible to scan across a range of m/z values, resulting in a mass spectrum.
