Title:ComparisonofISOSurfaceRoughnessCalibrationMethodsforSampleBlocks
Introduction:
Surfaceroughnessmeasurementplaysacrucialroleinvariousindustries,suchasmanufacturing,automotive,andaerospace.ISO(InternationalOrganizationforStandardization)standardsprovideguidelinesforensuringaccurateandconsistentsurfaceroughnessmeasurements.Onecriticalaspectisthecalibrationofinstrumentsusingstandardsampleblocks.ThispaperaimstocomparedifferentISOsurfaceroughnesscalibrationmethodsforsampleblocks.
