Difference between rough cut and finish cut in machining
Engineering

Engineering

Machining or metal cutting is one of the secondary manufacturing processes by which excess material is gradually removed from a preformed blank to obtain desired shape, size and finish. There exist larger number of processes to fulfil the basic requirement of machining. Such processes can be broadly classified as conventional machining processes (turning, threading, facing, drilling, boring, shaping, planing, milling, grooving, reaming, etc.), abrasive cutting processes (grinding, lapping, honing, polishing,

Engineering

Machining or metal cutting is one type of secondary manufacturing process by which excess material is gradually removed by shearing from pre-formed blank in the form of chips using a wedge shaped cutting tool to obtain desired shape, size and finish. It is one subtractive manufacturing process, which indicates layer by layer material is removed to get desired form. There exist a large number of such processes—each having different capability

Engineering

Metal cutting or machining is one of the secondary manufacturing processes by which excess material is gradually removed by shearing from a pre-formed blank in the form of chips using a wedge shaped cutting tool in order to obtain intended form having better finish, high dimensional accuracy and close tolerance. It is one type of subtractive manufacturing process where layer by layer material is removed from a solid blank to

Engineering

Machining or metal cutting is one secondary manufacturing process where excess material is gradually removed from the workpiece in order to impart desired finish, dimension and tolerance. To cater the need of efficiently and economically machining a wide variety of materials in different ways, several relevant processes have emerged over the years. Broadly these processes can be grouped as conventional machining (macro and micro), abrasive finishing and non-traditional machining (NTM).

Engineering

Machining or metal cutting is one subtractive manufacturing process that is predominantly used to remove unwanted material from workpiece to improve dimensional accuracy and tolerance. Over the ages multifarious machining processes have been evolved for efficient processing of a larger variety of materials in innumerable ways. Broadly such processes can be classified as conventional machining processes, abrasive finishing processes and non-traditional machining (NTM) processes. By definition, conventional machining is one

Fabricating complicate shaped products with good surface finish by casting is not always feasible and economical. Various secondary operations can be performed on the casted products to finally produce the desired object. Such operations include joining (such as welding), material removal or machining, heat treatment or property alteration, coloring and coating, etc. Material removal processes basically removes material from workpiece surface to provide intended dimension and tolerance.
