In addition, to bring some factors into account such as the thickness of nickel substrate and grit of CBN abrasives, the certain amount of material should be removed from the matrix.
In gear-honing with plated CBN honing wheel, cutting depth is related with radial force of honing tooth, normal pressure angle at pitch circle, contact points of homonymous teeth, material's elastic modulus, Poisson's ratio and other factors; 5.

Tribology is the science and the technologies of interacting surfaces in a relative motion.
One of the most important information sources is having the results of ferographical analysis (a type, a size, material composition, distribution, morphology, speed of generation, etc.) and particles wear in real time, or lubrication oil degradation obtained by using the methods FTIR (Fourier Transform using Infra-Red light), etc.
Modifying the maintenance will help to reduce manpower, save time, energy and material.
