Surface Finish Testing - The Present State-of-the-Art and Its Future 700144

The paper describes the present acceptance of surface texture measuring instruments in use in the United States giving recent statistical data related to other measuring techniques and machine tools used in the manufacturing process.
It then deals with the significance of surface roughness measurement and its hoped-for relation to part function with recent statements of available correlation. Recent trends in the United States, Europe, the Far East, and behind the Iron Curtain describe broadly the relation between American and foreign efforts in the field.
The necessity to carry the stylus instrument to its ultimate perfection, to consider nonstylus instruments for surface texture in their proper place, and the challenge of “surface quality and surface integrity” are described, as is the future need to relate surface quality measurement to other part measurements required for comprehensive part description.
