Abstract
A procedure whereby head wear can be numerically simulated is
described. Wear is assumed to be proportional to a material constant
times the contact pressure. Based on this assumption, the change in head
contour due to wear is calculated in incremental steps starting from any
initial contour. Simulation data are compared to an experimental
measurement of head contour change due to wear. It is noted that the
simulation of mechanical wear allows the evaluation of head geometries
for their performance after wear. Wear of composites can be modeled with
the simulation as well as preferential wear of thin-film head elements.
Additionally, the model gives insight into the final lapping process for
head manufacture
