Isotropic Mass Finishing for Surface Integrity and Part Performance : Products Finishing

Moreover, the increased complexity and precision requirements of mechanical products have reinforced the need for accurately producing and controlling the edge and surface finish of manufactured parts. Variations in the surface texture can influence a variety of performance characteristics. The surface finish can affect the ability of the part to resist wear and fatigue; to assist or destroy effective lubrication; to increase or decrease friction and/or abrasion with cooperating parts; and to resist corrosion.

Isotropic Surafce Finishes — Part 2

Isotropic Surafce Finishes — Part 2

The load bearing capability of this type of surface is substantially improved over nonisotropic conventionally produced surfaces. The lack of machining/grinding grooves or notches also limits crack propagation in high stress and strain loading situations.
