ActiveGeometrical product specifications (GPS) - Surface texture - Profile method - Motif parameters
产品几何技术规（GPS） 表面结构 轮廓法 图形参数
Application Summary AI generated
This standard specifies the definition and evaluation of motif parameters for surface texture using the profile method, which are used to characterize functional surface features like waviness and roughness in engineering components. It is applied in manufacturing and quality control contexts, particularly for precision parts in automotive, aerospace, and machinery industries, where surface finish impacts performance, wear, and sealing. The standard provides a unified basis for inspection and specification in metrology laboratories and production environments.
