在过去的十年中，工程界，尤其是汽车界已经意识到，产品寿命、油耗和效率与某些表面粗糙度参数之间存在一定的关系。这推动了表面测量计量技术的发展，尤其是当它应用于气缸壁的珩磨时。表面光洁度参数、过滤和方法已被证明足以预测表面性能。特别是，RK参数、相位校正滤波、改进的设备能力以及对表面光洁度方法的理解，使产品质量和性能有了显著提高。

DURING THE LAST DECADE THERE HAS BEEN A REALIZATION BY THE ENGINEERING COMMUNITY, PARTICULARLY THE AUTOMOTIVE COMMUNITY, THAT THERE IS A DEFINITE RELATIONSHIP BETWEEN PRODUCT LIFE, OIL CONSUMPTION AND EFFICIENCY WITH CERTAIN SURFACE ROUGHNESS PARAMETERS. THIS HAS DRIVEN THE TECHNOLOGY OF SURFACE MEASUREMENT METROLOGY, PARTICULARLY AS IT APPLIES TO THE HONING OF CYLINDER WALLS. SURFACE FINISH PARAMETERS, FILTERING AND METHODOLOGY HAVE PROVEN SUFFICIENT TO ALLOW PREDICTION OF SURFACE PERFORMANCE. IN PARTICULAR, THE RK PARAMETERS, PHASE CORRECTED FILTERING, IMPROVED EQUIPMENT CAPABILITY AND AN UNDERSTANDING OF SURFACE FINISH METHODOLOGY HAS RESULTED IN DRAMATIC IMPROVEMENTS IN PRODUCT QUALITY AND PERFORMANCE.
