Abstract
Limitations in the ability of surface texture assessment methods to evaluate truly the probable performance of surfaces under operating conditions are widely known. As the micro-geometric asperities of surface texture are very complex in character and as the conditions under which surfaces must operate are so varied, direct correlation of the two by means of simple indices is relatively impossible. While investigation of methods of assessment might provide consuming scientific and academic interest, as well as an intriguing diversion for those in metrology, such effort is of little avail unless it can be useful in enabling industry to produce better products at lower cost.
International effort is under way to reach world-wide agreement on standards for assessment devices, methods of evaluation, reference specimens and drafting room standards for designation.
Precise and accurate control of surface texture is increasingly important to product performance in advancing technology. Success depends upon personnel who have a thorough knowledge of the limitations of existing methodology as well as the broad perspective necessary to evaluate factors in terms of company goals.
Credos for engineers, manufacturers and quality personnel are given to assist in the human factors that play such an important part in the successful use of any assessment system.
