electroplating - wikipedia

Electroplating is a general name for processes that create a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current.The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the electrolyte is a solution of a salt of the metal to be coated; and the anode (positive electrode) is usually either a block

The challenge for educators, therefore, is how to design instruction for both machines and humans, and how the two can interact with each other. For example, if there is a change in a procedure on how to use a machine, the wireless capability in the machine will allow the updated procedure to be downloaded into the machine s memory

a review on pineapple leaves fibre and its composites

Natural fibre based composites are under intensive study due to their ecofriendly nature and peculiar properties. The advantage of natural fibres is their continuous supply, easy and safe handling, and biodegradable nature. Although natural fibres exhibit admirable physical and mechanical properties, it varies with the plant source, species, geography, and so forth

V.C. Chandrasekaran, in Essential Rubber Formulary, 2007 9.1 Introduction. Oil seals and O rings are used in all hydraulic systems, pumps, pistons, pipe connections, etc. An oil seal used for sealing a rotating member is called a rotary seal. O rings are also used for a similar purpose. Oil seals are used to protect shafts and bearings from ingress of dirt and foreign matter and

computerized simulation of thread form grinding process

Apr 01, 2009 Likewise, the instantaneous contact line on the ground wheel surface in system S 2 can be expressed as follows: (12) r 2 (c) = M 21 r 1 (c), where M 21 is the inverse matrix of M 12. As shown in Fig. 7 , the proposed simulation method can be used to draw the instantaneous contact lines on the surfaces of the grinding wheel and ground thread

predictive modeling of grinding force in the inner thread

Jun 11, 2019 Grinding force is an important factor to consider in the field of precision manufacturing. In this study, a model of the thread grinding force in inner thread grinding that takes into account the thread helix angle and effect of grains overlapping is presented. The average undeformed chip thickness of a single abrasive grain can be obtained based on the Rayleigh probability density function

The method has been in use for many years in the wheelhead slideways of Matrix thread grinding machines. The heavy wheelhead unit of such a machine is required to make very small displacements (often as little as a few thousandths of a millimetre) positively and with a light control. The rolling motion of this type of slideway provides the
