Introduction

Concepts of Production, Manufacturing & Machining

Concepts of production, manufacturing and machining in mechanical engineering are discussed here. In general there relation can be described as “machining is a subset of manufacturing, which itself is a subset of production”. Read details…


Primary, Secondary and Advanced Manufacturing Processes

Concepts of primary, secondary and advanced manufacturing processes are discussed here with examples. Primary processes convert raw material to a basic shaped product. Secondary processes further improve the properties, quality, tolerance, etc. Advanced processes directly provide good properties and qualities. Read details…


Additive Manufacturing & Subtractive Manufacturing

Concepts of additive manufacturing and subtractive manufacturing, their applications and relative advantages and disadvantages are discussed here. In AM, material is added one over another, whereas in SM, material is removed layer by layer to build a solid 3-D component. Read details…


Definition of Machining or Metal Cutting

Machining is one manufacturing process by which excess material is removed by shearing from a pre-formed blank in the form of chips using a wedge shaped cutting tool in order to get desired shape, finish and tolerance. Examples include turning, milling, facing, drilling, boring, knurling, grinding, etc. Read details…


Concepts of Machine, Machine Tool and Cutting Tool in Machining

Relationship among machine, machine tool and cutting tool is described here. If a machine is power driven and non-portable and can perform one or more material removal task using a cutting tool, then it is a machine tool. Cutting tool is wedge shaped device mounted on machine tool to remove material from workpiece. Read details…
