* Has always been at the forefront of technologies for turbine, rocket, reciprocating engines, power systems, etc.
== Utility ==
* A Tool using this technology has a diamond at a specified precise orientation affixed to the tip of the shank of the machine Enabling markings on various metal surfaces for
* Identification purposes
* Surface treatment
* Surface condition
* The point of the tool strikes the surface of metal and on impact creates a cold-formed indentation or mark.

* '''Stereographic projection triangle for the diamond crystal'''
Represents a 3D orientation spread out on a 2D plane.
Figure depicts the orientation of the diamond tip.
It Shows the axis of orientation of the diamond crystal w.r.t three standard orientations of the crystal marked by the 3 vertices.The pole of the crystal should lie within the dotted circle to achieve the super wear resistance orientation
== Importance of the orientation ==
* Diamond crystals are anisotropic
* Their mechanical and physical properties vary with their crystallographic orientation
* The orientation of the crystal governs its strength and wear resistance
* This particular '''super wear-resistant orientation''' has been discovered and patented by Pratt and Whitney.
== Limitations of other technologies ==
* Carbide and non-oriented diamond indenters have problems such as
# Wear and tear of tool head
# Replacement costs
== Advantages of this tool ==
* '''Economical'''
# Low replacement costs because of increased tool life (up too 100 times that of carbide tools)
# Reduced cost per mark
* '''Quality'''
# Better reading of 2D markings
# Improved marking reliability and quality
* '''Physical'''
# Improved wear resistance
# Less force required to obtain indention depth
== Applications ==
* Aero & Industrial Gas Turbines
* Railway
* Machineries
* Weapon markings
* Punches and Dies
* Cables and Wires
* Weapon markings
* Any metal equipment
