Joining is an integral part of manufacturing as it facilitates easy, efficient and economic production of intricate shaped parts. Basic purpose of joining is to assemble two or more solid components together in such a way that it can form a single unit and can subsequently perform intended functionalities. To serve this purpose, a number of joining processes has evolved throughout the ages that can join structural members in different
In the context of manufacturing or mechanical engineering, three terms, namely machine, machine tool and cutting tool have different significance. Basically machine is any device that reduces human effort in doing a task. By formal definition, a machine is an assembly of mechanisms that are clustered together in such a way that it can perform certain operations by utilizing electrical, mechanical, hydraulic and/or pneumatic power. So a machine is mostly
Requirement for joining of two or more components is inherent to manufacturing. There exist various joining techniques to assemble a wide variety of materials in multifarious ways. Some of these processes provide permanent joints, while others provide temporary joints. Like riveting, coupling and adhesive bonding, welding is also one permanent joining process. By definition, welding is one of the joining processes by which two or more solid components can be
Manufacturing, a crucial step in production system, converts raw materials and scraps into useful products by adding sufficient value. However, all physical products cannot be produced in same way. Accordingly there exist several manufacturing processes in order to fabricate different objects made of different materials and having varying features. Such manufacturing processes include casting, joining, forming or metal working, machining or metal cutting, heat treatment, coating and coloring, rapid prototyping
Manufacturing is one crucial step in production that actually converts raw materials or scraps into desired products by adding substantial value. Several manufacturing processes exist to cater the need of processing wide variety of materials in sweeping ways. Growing need for miniaturized products with better surface quality and more inbuilt functionalities paved the way for rapid development of manufacturing and as a consequence various sophisticated processes have evolved that can
Machining or metal cutting is one subtractive manufacturing process where excess material is gradually removed in the form of chips from preformed blank using a cutting tool in order to impart intended shape, size and surface finish. To continuously remove (shear off) layers of material, a sharp edged cutter is indispensably necessary. During machining, relative motions are provided between workpiece and cutting tool in particular directions based on geometry of
Feasibility of making a product from natural organic or inorganic resources depends on the advancement of science and is accelerated by the human need. However, easy, efficient, productive, economic and ergonomic conversion of raw materials to useful products as per the customers’ requirement relies on the growth of technology and assistance of management and planning. Although it is not always feasible to fulfil every requirement in a single product, in
