Difference between machine and machine tool

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

Difference between machine tool and cutting tool

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

Same ORS and NRS Tool Nomenclature

Geometry of the cutting tool is one crucial factor that influences overall performance (machinability) as well as productivity of machining. Thus cutting tool must be selected judiciously prior to machining based on the work material and cutting conditions. Tool signature displays various features of a cutting tool, and thus it enables quick selection of a cutting tool for specific application. There are several standard systems for designation of a single

Schematic diagram of three deformation zones in machining

Machining or metal cutting is one subtractive manufacturing process that indicates layer by layer material is gradually removed from the workpiece to impart desired shape, size and finish. In conventional machining processes (such as turning, threading, milling, facing, drilling, boring, etc.), material is removed with the assistance of a wedge shaped cutting tool. Here the cutting tool compresses a thin layer of work material and gradually shears it off in

Differences between turning and milling

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,

Difference between single point and multi point cutting tool

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
