Basic properties that cutting tools must possess are: Tool material must be at least 30 to 50% harder than the workpiece material. Tool material must have high hot hardness. High toughness High wear resistance High thermal conductivity Lo…

Whenever the tool is not performing the machining operation satisfactorily, there is a cutting tool failure. The following drawbacks are observed if the tool fails. The tool ceases to produce the workpiece according to the required dimensions. The tool gets…

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…
