1.3 WORKING PRINCIPLE OF MILLING MACHINE Working of a milling machine is based on the fact that milling cutter is fed against workpiece. This is achieved by developing relative motion with precise control between workpiece and rotating milling cutter. Feed motion is generally given to the workpiece through its holding device.

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.

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.

A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

The working of a grinding machine: A grinder features an electric motor that supplies motion power to the grinding wheel using pulley and belt. For the portable grinder, the rotor is inside the grinding machine and the power switch is located beside the handle of a grinder. So, the switch must be pressed before the grinder works.

7. Countersinking: Conclusion: 1. Drilling: Drilling is the most important and common drilling machine operation. In the drilling, we usually, produce a cylindrical hole inside the workpiece and remove the material inside it. Here, the material is removed by the rotating edge of the cutting tool. And that rotating edge is called a drill.
