Simulation to Microtopography Formation of CBN Active Abrasives on a Honing Wheel Surface

The microtopography of a honing wheel surface composed active abrasive grains is the key factor affecting characteristics, and control it sufficient condition to realize high-efficiency precision honing. Based on magnetron sputtering method phase field method, theoretical model cubic boron nitride (CBN) coating formation established. physical vapor deposition (PVD) discrete equation solved by finite difference method. A MATLAB program compiled simulate process micromorphology CBN surface. Taguchi designed study relationships time, substrate temperature, gas flow rate, reaction space with number abrasives length, width, height, size abrasives. simulation results are highly similar scanning electron microscopy (SEM) examinations, which shows that can accurately effectively morphology under different conditions provide basis for prediction wear
