Filter is 100Hz Sample rate is 1000 samples sec The head was operated in diffuse [...]
Transportation Railroad Track Quality Surface Description
Road Surface Quality Transportation Road Surface Quality Surface Description Introduction Various Departments of Transportation (DOTs), both nationally and internationally, are developing and incorporating automated road quality inspection equipment. “It is well known that the characteristics of the road surface, especially for the surface layer, are [...]
Grinding Process Automotive Grinding Process Surface Description A cylindrical grinding process finishes most wheel spindle surfaces. It is essential that this grinding process leave a surface finish that is smooth and free of defects with minimal runout. No grinder produces a perfect surface. Grinder wheel [...]
Semiconductor Wafer Thickness, Bow, Warp And Ttv Surface Description Thickness Measurement ASTM F657: The distance through a wafer between corresponding points on the front and back surface. Thickness is expressed in microns or mils (thousandths of an inch). Total Thickness Variation (TTV) ASTM F657: [...]
Wafer QA/QC After Slicing And Polishing Semiconductor Wafer Qa/Qc After Slicing And Polishing Surface Description Introduction: When wafers are sliced up with wire saws, they are measured to make sure they are within the specified thickness, with minimal bow, warp, and TTV. After initial measurement, they [...]
Torque Converter Automotive Torque Converter Surface Description Since minute defects in the torque converter casing wall thickness can result in unacceptable and dangerous torque converter expansion, a precision measurement system was needed to measure the impeller hub displacement and thus the torque converter axial displacement. [...]
Brake Rotors Thickness Variation Automotive Brake Rotors Thickness Variation Surface Description Introduction Driving cross country or cross town, we give little thought to the operation or complexity of our vehicle braking systems. They only cross our mind when we absolutely need them; we never stop to [...]
