Machining is one type of manufacturing process where excess material is removed from the workpiece to impart intended shape, size and finish. It follows the principle of subtractive manufacturing approach to build 3-D components. Conventional machining processes employ a cutting tool that contain one or more shape edges, and layer by layer material is removed from the workpiece in the form of solid chips. In order to process a wide
In the field of mechanical engineering, “Machine” is defined as 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, and thereby reduces the requirement of human effort and intervention in doing the task. However, “Machine Tool” is not exactly same with the machine. The term Machine includes wide variety of machinery, whereas Machine
In the field of mechanical engineering, Machine is defined as an assembly of mechanisms that are clustered together to perform certain operations by utilizing electrical, mechanical, hydraulic and/or pneumatic power. Total number of mechanisms exist within a machine may vary from just few to few hundreds! Accordingly size of a machine also varies. Some machines, irrespective of their size, are portable. For example, a hand drill (small machine) and a
Machining is basically one material removal process where excess material is sheared off by the mutual interaction between workpiece and cutting tool. There exist several machining processes to cater the need of processing a wide variety of workpiece materials in innumerable ways. For examples, lathe operations (such as straight turning, taper turning, internal turning, threading, grooving, etc.) are primarily carried out to generate cylindrical or conical surfaces. Milling operations are
Conventional machining is one type of manufacturing process in which excess material is removed from a pre-formed blank by shearing in the form of chips using a wedge shaped cutting tool in order to get desired shape, finish and tolerance. There exist several machining processes to efficiently machine a wide variety of materials in innumerable ways. Turning and milling are just two examples of such machining processes. Others being tapering,
Cutting Tool or Cutter is a wedge shaped device that compresses the workpiece material during machining to gradually remove excess material by shearing in order to obtain desired shape, size and accuracy. Geometry, orientation and material are three important factors that influence performance of a cutting tool in accomplishing material removal. Every conventional machining operation employs a physical cutting tool. Although basic shape and feature of such cutting tool vary
Milling is one type of conventional machining process primarily for generating flat or stepped surfaces. In peripheral milling, cutting velocity is imparted by rotating the milling cutter about a fixed horizontal axis; whereas, the feed rate is imparted by moving the workpiece (basically worktable) against the rotating milling cutter. Since both cutting velocity and feed rate are vector quantities, so based on their mutual directions, peripheral milling can be classified
