Appliions of Optical Sensors. Appliion of these optical sensors ranges from computers to motion detectors. For optical sensors to work effectively, they must be the correct type for the appliion, so that they maintain their sensitivity to the property they measure. Optical sensors are integral parts of many common devices, including ...
Grinding, lapping, polishing, and CMP (chem.mechanical polishing) are all techniques used for precise removal of material. A brief discussion of terms is needed to understand the basics of what is being referred to when these topics are discussed. : Grinding Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large ...
A Planar grinding machine, like the PlanarMet 300 planar grinding machine shown in Figure, utilizes a fixed abrasive stone for rapid sample grinding. This type of automated grinder produces planar samples in 12 minutes replacing up to 3 traditional grinding steps. Machines like this can be benchtop or floor standing and typically utilize the same sample holders as grinderpolishers to ...
One of the problems induced is that if the grinding wheel designed for point contact grinding has a complex profile, the workpiece shape accuracy will be badly affected as a result of the rapid ...
Grinding machines, like broaching machines, operate over a range of speeds depending on the type of machine being range from approximately 1250 to 2000m min −1, although in highspeed grinding speeds of up to 5400m/min are achievable (Schey, 1987).The two most common grinding appliions are cylindrical grinding and surface grinding.

The working principle of a grinding machine is quite easier to understand. In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley. So when we start the electric motor the motor rotates at a certain rpm ( RPM, it may change according to the types of grinding machine) with the help of vbelt and cone ...
Grinding – Ex. 11 • You are grinding a steel, which has a specific grinding energy (u) of 35 Ws/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at m/min. The chip thickness ratio (r) is 10.

· In this paper, in order to grind optical aspheric surfaces with high quality and high precision, some factors that influence the roughness and profile accuracy of machined surfaces were theoretically analyzed. At the same time, all kinds of parameters of ultraprecision grinding optical aspheric surface in ductile mode were optimized. Afterwards author developed the ultraprecision aspheric ...
· An Optical Profile Projector is a type of comparators. What is meant by a projector? A projector is an optical device, which enlarges the image. This is the principle we are going to use it in the Optical projector comparator. This Optical Profile of projectors is used to check relatively small engineering components with the working standard.
· This grinding machine works in the generating grinding method, the work principle of which is the same as the hobbing machine. Three translational axes (X, Y, and Zaxis) and two rotary axes (B and Caxis) are employed in this machine, and the two rotary axes are both driven by servomotor without any decelerating mechanism. The spindle (Baxis) consists of a grinding wheel .
The 'grinding' process is subject to principles similar to those known from other machining processes. The 'grinding tool' is made up of abrasive grains and pores and exhibits an irregular distribution of cutting edges. As opposed to all other operations such as milling or lathing, negative cutting angles occur during grinding, leading to unfavourable chipping conditions. The correct ...
grinding machine gage is usually the incoming air pressure, which is not necessarily equal to the pressure of the specimens against the platen. Perforated or grooved platens are available that aid in the removal of swarf. Experiment with the abrasive size, contact pressure, relative rotation directions (same or opposite), and frequencies shown subsequently to attain the best results. Typical ...

· Typically, CNC grinding machines are used for camshafts, ball bearings, transmission shafts, and other working pieces, which require an accurate and correct finish. Numerous pieces made using a CNC grinding machine are cylindrical. A grinding machine also use to make other types of workpieces. In CNC grinding machines "CNC" holds for ...
· But when you OD grind, there is only one wheel, which must work against the workpiece in order to grind. It is the continuous rotation of both workpiece and grinding wheel that makes the grinding action possible. In that way, OD grinding is similar to surface grinding, where there is only one wheel. However, one big difference is that in ...
Working of Optical Fiber. The working principle of optical fiber is the transmission of the information in the form of light atoms otherwise photons. The cores of the fiberglass the cladding have a special refractive index to twist inward light at a particular angle. Whenever light gestures are transmitted through the optical cable, then they do not reflect the cladding core within a ...
