Profile projector is widely used for complex shape stamping, gears, cams, threads and comparing the measured contour model. It’s easy to use and highly efficient. It is a commonly used measurement of optical instruments. Thus, profile projector is widely used in major machinery manufacturing including aviation, aerospace industry, watches and clocks, electronics, instrumentation industry, research institutes and detection metering stations at all levels and etc.

The Digital Caliper (sometimes incorrectly called the Digital Vernier Caliper) is a precision instrument that can be used to measure internal and external distances extremely accurately. The example shown below is a digital caliper as the distances/measurements, are read from a LCD display. The most important parts have been labelled. Earlier versions of this type of measuring instrument had to be read by looking carefully at the imperial or metric scale and there was a need for very good eyesight in order to read the small sliding scale. Manually operated vernier calipers can still be bought and remain popular because they are much cheaper than the digital version. Also, the digital version requires a small battery whereas the manual version does not need any power source.
Digital calipers are easier to use as the measurement is clearly displayed and also, by pressing the inch/mm button the distance can be read as metric or imperial.
The display is turned on with the on/off button. The external jaws should then be brought together until they touch and the zero button should be pressed. The digital caliper can then be used to measure distances. Always go through this procedure when turning on the display for the first time.
MEASURING EXTERNAL DISTANCES
The material to be measured is placed between the external jaws and they are carefully brought together. The locking screw is tightened so that the jaws do not move apart. The digital display can then be read. The distance can be read by in metric and imperial by pressing the inch/mm button.

Electrical Discharge Machining (EDM), a manufacturing process whereby a desired shape is obtained using electrical discharges, is primarily used to cut hard metals and other materials that would be impossible to machine with traditional techniques. Sometimes referred to as “spark machining” or “spark eroding”, EDM is a non-traditional method of removing material by a series of rapidly recurring electric arcing discharges in the presence of an energetic electric field. EDM can cut small or odd-shaped angles, intricate contours or cavities in pre-hardened steel.
The EDM cutting tool is guided along the desired path. Consecutive sparks produce a series of micro-craters on the workpiece and remove material along the cutting path by melting and vaporization. The particles are washed away by the continuously flushing dielectric fluid. It is also important to note that a similar micro-crater is formed on the surface of the electrode. These micro-craters result in the gradual erosion of the electrode, many times requiring several different electrodes of varying tolerances to be used or, in the case of wire EDM machining, constant replacement of the wire by feeding from a spool.
Wire-cutting EDM is commonly used when low residual stresses are desired. Wire EDM has no added residual stress because it has no cutting forces. There is little change in the mechanical properties of a material in wire-cutting EDM due to these low residual stresses.
CNC technology and the features and functions of machining centers. • the basic vertical knee mill machine is examined. • the parameters for successful metal removal are defined. • the application of CNC technology to milling is explained. • machining center features and functions are highlighted. • various cutting tools • various accessories.
Cutting tools are used to remove material from a workpiece during the manufacturing process. They are typically made of hard materials such as carbide or high-speed steel and come in a variety of shapes and sizes to suit different applications.

Indexable Turning is Inserts generally refers to any cutting tool where the cutting edge consists of a separate piece of material, either brazed, welded or clamped on to a separate body. Common materials for tips include cemented carbide, polycrystalline diamond, and cubic boron nitride. Tools that are commonly tipped include: Lathe, milling cutters (end mills, fly cutters), tool bits, and saw blades.

A micrometer, sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw widely used for precise measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are usually, but not always, in the form of calipers (opposing ends joined by a frame). The spindle is a very accurately machined screw and the object to be measured is placed between the spindle and the anvil. The spindle is moved by turning the ratchet knob or thimble until the object to be measured is lightly touched by both the spindle and the anvil.
