Abstract

The surface roughness refers to the parts on the surface with small spacing and tiny peak and valley of geometric shape micro characteristics. It develops in the process of mechanical processing, directly affecting the parts with nature, the surface of the wear resistance, corrosion resistance, fatigue strength, sealing, thermal conductivity and service life. According to the roughness of the geometry of the definition,we can measure the Ra, Ry parameters by profilometer.

3D design software Pro/E, video production software movie rubik's cube, sound processing software Goldwave, image processing software Isee and multimedia animation Authorware software. Quoting the multimedia technology, the experiment teaching becomes more interactive and interesting meanwhile enhancing students to master the experimental principle and get much more about the principle of profilometer.

Keywords: surface roughness; Authorware; profilometer
