Machine cutting tools are machines used to shape metal and other rigid materials by cutting, boring, grinding, shearing or deforming. They employ cutting tools made of materials harder than what is being cut to withstand heat and have a specific geometry. An ideal cutting tool is highly temperature stable, resistant to wear and tear, impact and chemically inert. Machine cutting tools are used to remove unwanted material and achieve a desired final shape, size and surface finish of a product in an economical way, though they can result in material loss and require skilled operation.

2.  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.

3.  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.

4.  Removing unwanted material.
 To get desired
1.Shape
2.Size
3.Surface finish
 Or we can say that to get a desired final
product.

6.  POSITIVES
 Closer dimensional accuracy Surface
texture/finish.
 Economical.
 Complex shape.
 Size.

7.  NEGATIVE
 Material loss upto 50%.
 Skilled operator
 Time consuming
 All material cannot be machined
 Special equipment
