Convex diamond patterns by grinding with a wheel which is ... - DeepDyve

Patterned surfaces such as longitudinal micro-grooves, micro-dimples, and micro-convex shapes have great potential for improving tribological properties by reducing wear, friction, drag and lubrication consumption. Convex diamond patterns can be generated by a special grinding operation in which the wheel has a single helical groove on its circumference. To obtain such patterns, the same wheel ...
