the coolant and abrasive residue from the grinding operation will damage the surface of the plate. 17. remove the v-block from the vice and stone any burrs from the ground edges. 18. it is preferable to use a “squeegee” to clean the magnetic chuck, remember it is highly dangerous to use rags around or near a rotating grinding wheel.
explanation: the washing machines use inverter control for both washing and spin-drying. inverter control helps reduce wash/spin noise and vibration and enables a washing machine to adjust the amount of water and motor torque to suit the washload. igbts are used for motor drive, and microcontrollers for overall control.
in a heart – lung machine, the gas bubbles are dispersed into the venous blood in the bubble column and acts as vehicles for both oxygen and carbon dioxide. here oxygen diffuses from the bubble into the blood film surrounding the bubble. various types of dispersion plates are used. 6. reservoir: a reservoir gather blood drained from the venous flow.
1 answer. (i) input devices: these are the devices which are used to input the part program in the cnc machine. there are three commonly used input devices and these are punch tape reader, magnetic tape reader and computer via rs-232-c communication. (ii) machine control unit (mcu): it is the heart of the cnc machine.

construction: the main parts of the double housing planer machine is bed and table, housings, cross rail, , tool heads, driving and feed mechanism. bed and table: the bed is a long heavy base and table made of cast iron. its top surface is flat and machined accurately. the flat top surface has slots in which the workpiece can be securely clamped.
the washing machine – sometimes combined with dryer - is the home appliance with perhaps the longest development history, with commercial models introduced as far back as the mid 1850’s! today they are required to clean more effectively while consuming less energy, water and detergent, and operate at the lowest possible noise levels while ensuring greater safety.
in this section, system block diagrams are introduced which are based on the relationship between the suspension force and the associated winding currents as derived in the previous section. the block diagrams are drawn for a few basic synchronous motor structures, i.e., an spm motor, a salient-pole permanent magnet motor and a synchronous reluctance motor.
(ii) machine control unit (mcu): it is the heart of the cnc machine. it performs all the controlling action of the cnc machine, the various functions performed by the mcu are. it reads the coded instructions fed into it. it decodes the coded instruction. it implements interpolation ( linear, circular and helical ) to generate axis motion commands.
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 irregularities from the surface. the grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. grinding is quick and relatively easy process but can

throughout the grinding wheel's history, the bond that holds the abrasive grains together has proven as important as the grains themselves. the success of grinding wheels began in the early 1840s, when bonds containing rubber or clay were introduced, and by the 1870s a bond with a vitrified or glass-like structure was patented.
