A machine tool is a machine for shaping or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformation.
Machine tools employ some sort of tool that does the cutting or shaping.
Cutting tools must be made of a material harder than the material which is to be cut.
Machine tools
The tool must be able to withstand the heat generated in the metal-cutting process.
The tool must have a specific geometry.
An ideal cutting tool material must possess the following characteristics:
High Temperature stability. Resistance against wear and tear. Impact resistant. Chemically inert to work material and cutting
fluid.
Removing unwanted material. To get desired 1.Shape 2.Size 3.Surface finish Or we can say that to get a desired final
product.
MACHINING
POSITIVES Closer dimensional accuracy Surface
texture/finish. Economical. Complex shape. Size.
FEATURES
NEGATIVE Material loss upto 50%. Skilled operator Time consuming All material cannot be machined Special equipment
