Kod eksploatacije strojnih dijelova zbog trenja na površini dolazi do promjene geometrije oblika. Prilikom ispitivanja ekonomske isplativosti zamjene postojećih pozicija (vratilo i matica vijčane preše), došlo se do zaključka da je najisplativija investicija izrada nove matice prema već postojećem vratilu. Prije početka izrade matice bilo je nužno usporediti postojeće vijčano vreteno preše s postojećim CAD modelom. Na osnovi usporedbe mjerenja došlo se do zaključka da je novu maticu potrebno izraditi po dijelu vretena koje je najviše istrošeno.
Nakon samo nekoliko sati dobiven je oblak točaka vratila vijčane preše. Nakon toga se pristupilo poligonizaciji oblaka točaka te se za rezultat dobio STL model. Zadnji korak je bio izrada mjernog izvještaja tj poklapanje izmjerenih podataka s CAD modelom.With the exploitation of machine parts due to friction on the surface, there is a change of geometry shapes. While examining the economic feasibility of replacing the existing position (shaft nut and screw presses) it was concluded that the most cost-effective investment is creating a new parent to an existing shaft. Before starting to produce nuts, it was necessary to compare the existing screw spindle presses with an existing CAD model. A comparison of measurements led to the conclusion that it is necessary to create a new nut down on the most depleted spindle.
After just a few hours a cloud of points back screw presses was produced. Afterwards, a polygonization point cloud was made and the result was a STL model. The last step was the development of measurement reports, i.e. matching the measured data with the CAD model
