Comparison of solids, liquids and gases (fluids) can be done in aspects like macroscopic description, mobility of molecules, density, molecular spacing, effect of shear stress, effect of normal stress, viscosity and compressibility is represented below in tabular form…

A lathe machine is a mechanical device in which the workpiece is rotated against a suitable cutting tool to produce cylindrical forms in metal, wood or any other machinable material. Figure 1: Lathe machine Various types of lathe machine tools: Copy Lathe Automat…

The method of adhering or welding microchips or powdered particles present during machining to the rake face of the cutting tool is called built-up edge (BUE). During the machining operation , there are always a certain number of microchips or powdered particles that …

Comparison of various machining processes (boring, drilling, shaping, planning, turning and milling) in aspects of advantages and limitations. S.No Machining Process Advantages Limitations 1 Boring All types of material can be bored. A variety o…

Various functions of cutting fluids are Cutting fluid cools the workpiece and tool by carrying away the heat generated during machining. It acts as a lubricant at the friction zones, increasing tool life . As friction decreases, the forces and electricity power consum…

The tool life can be defined in three different ways. Tool life is the actual machining time between two successive regrindings of a cutting tool. It is most commonly expressed in minutes. Volume of material removed in mass production. Number of workpieces machined …

The elements of tool signature or nomenclature of single point cutting tool is illustrated in the figure below (i) Back rake angle: Back rake angle is the angle between the face of the single point cutting tool and a line parallel with base of the tool measured in a…
