ActiveGeometrical Product Specifications(GPS)--Surface texture: Profile method--Surface having stratified functional properties--Part 2: Height characterization using the linear material ratio curve
产品几何量技术规范(GPS) 表面结构 轮廓法 具有复合加工特征的表面 第2部分: 用线性化的支承率曲线表征高度特性
Application Summary AI generated
This standard specifies the method for characterizing the height properties of surfaces with stratified functional properties, such as those produced by plateau honing or lapping, using a linearized material ratio curve. It is applied in the automotive and manufacturing industries to evaluate the wear and lubrication performance of engine cylinder bores, bearing surfaces, and other precision components. The standard provides a quantitative basis for quality control in production and acceptance testing of surfaces requiring specific functional behavior under load.
