![]() ![]() ![]() Most of these conventional processes can machine a large variety of materials however, certain work materials don’t provide acceptable machinability and therefore other material removal processes (such as abrasive cutting or NTM) are recommended in those cases. ![]() This cutting tool should also possess a defined specification and compatible material for uninterrupted and efficient machining. A hard and sharp cutting tool or cutter is mandatorily employed for removing material by shearing. Such processes can provide higher material removal rate (MRR) and thus are suitable, productive and economic for bulk removal of work material. To fulfill this demand, there exist various machining processes like turning, threading, tapering, chamfering, spinning, tapping, necking, filleting, facing, grooving, parting, knurling, drilling, milling, shaping, planning, slotting, boring, hobbing, broaching, etc. Among them conventional machining processes are age old and at the same time reliable however, various abrasive cutting processes and so-called non-traditional machining (NTM) processes can also provide similar facility.īy definition, machining or metal cutting is one of the secondary manufacturing processes by which layer by layer material is gradually removed in the form of chips from a preformed blank in order to obtain desired shape, size and finish. A large number of such processes exist to cater the need of processing variety of materials in various ways and to finish their surfaces at different levels. Material removal processes basically removes material from workpiece surface to provide intended dimension and tolerance. Such operations include joining (such as welding), material removal or machining, heat treatment or property alteration, coloring and coating, etc. Various secondary operations can be performed on the casted products to finally produce the desired object. Fabricating complicate shaped products with good surface finish by casting is not always feasible and economical. ![]()
