What is an aerodynamic object? On the basis of resistance provided by the objects to the air, objects can be divided into two parts. Aerodynamic objects and Non-aerodynamic objects An aerodynamic object offers least resistance to the air when either the object or the air is moving. On the other hand the resistance provided by… Read More »
What is lapping? Lapping is a finishing process, which is carried out using loose abrasives. In lapping process surface smoothing is achieved by the abrasive grains which are supported by the lap, which acts as a cutting tool shank. Diagram of lapping process Advantages of lapping: Extreme accuracy of dimensions Correction of minor imperfections of… Read More »
