Geometrical error, given by the production process, results in functional problems in hydro turbine system. These problems include less output power, vibration, cavitation, and friction between parts. Hence, dimentional and <br /> <br /> <br /> geometrical measurement become the fundamental and essential action to be done in each production processes to prevent or reduce further functional problems. <br /> <br /> <br /> Dimentional and geometrical verification for each parts in manufacturing processes are needed to know how the quality of the parts. This final project focuses on the most crucial part in the runner, the blades. <br /> <br /> <br /> Laser scanner was utilized as a scanning device which converting physical model into digital model. Using this non contact measuring technology, geometrical verification was done by comparing the scanning data (actual blade) <br /> <br /> <br /> to nominal CAD model. Pro/Engineer and Geomagic Studio are employed as the geometrical measuring softwares. Measuring steps of scanning data in these softwares are clearly given to show the procedures. Measuring analysis for blades, especially the outlet opening, shows a good condition of blades’ geometry. This is shown from the maximum angle deviation which is in the value of 0.6 o. If it is converted into distance, that will be -2.41 mm from its average. Moreover, this also means that maximum distance deviation is -2.5%.
