Wide range three-dimensional roughness measuring system

Abstract A wide range three-dimensional roughness measuring system is described. A precision x-y traversing table moves the sample and surface asperity heights are measured with a conventional stylus profilometer. The system can measure an area of 300 mm × 400 mm and divide the area into 5 × 19 9 different locations. A new plot program which gives a true perspective picture is used, a new way of presenting the bearing area is shown and possibilities for studying exactly the same spot between experiments are given. A method for eliminating the vibrations from the system is also given.
