Allotrope
Two or more different physical forms in which an element can exist. Graphite and diamond are allotropes of carbon.
cBN
Is the second hardest material after diamond; particularly suitable for machining ferrous materials.
EDG
Electric Discharge Grinding is a process similar to electric discharge machining (EDM), except that, a rotating electrode is used.
EDM
Electric Discharge Machining is a manufacturing process where material is removed from a workpiece by a series of rapidly recurring electric discharges (sparks). These sparks occur between two electrodes separated by a dielectric liquid.
Laser
An acronym for:
Light Amplification by Stimulated Emission of Radiation.
Lasers cut by focusing the output of a high-power laser on or near the surface of the material to be cut.
PCD
PolyCrystalline Diamond.
PCBN
Polycrystalline Cubic Boron Nitride.
PCP
PolyCrystalline Products i.e. PCD, PCBN and PDC.
PDC
Polycrystalline Diamond Cutters - a term used in the oil well bit industry.
Superhard material
Superhard material is a material with a hardness value exceeding 40GPa.
Tetrahedral
In tetrahedral molecular geometry, an atom is located at the center with 4 substituents located at the corners of a tetrahedron. The bond angles are 109.5° when all 4 substituents are the same, as in methane and diamond.
WEDM
Wire Electric Discharge Machining.
