20.500.12556/DKUM-68062 Končna obdelava orodij za preoblikovanje pločevine s postopkom mikrokovanja površin Final treatment of tools for processing sheet metal with machine hammer peening Mikrokovanje je tehnologija, ki še ni razširjena v industrijski praksi. Temelji na postopku, kjer kroglica iz karbidne trdine premera od 4 mm do 20 mm s frekvenco okoli 200 Hz udarja ob površino obdelovanca ter s tem površino gladi, utrjuje ter odpravlja notranje napetosti. V okviru naloge sem raziskoval najoptimalnejše parametre za uporabo v proizvodnem procesu proizvodnje orodij za preoblikovanje. Rezultati so pokazali vidno izboljšanje hrapavosti, prav tako tudi povečanje trdote. Težave so se pojavile zaradi premajhnega spomina robota, zaradi toleranc robota in napak pri kalibraciji orodja ter obdelovanca. Postopek mikrokovanja skrajša čas, ki je potreben za ročno obdelavo. Machine hammer peening is relatively new technology, which is not yet widespread in manufacturing process. Basic principle of this technology is that a sphere made of hard metal with diameter from 4 mm to 20 mm with frequency around 200 Hz punches the surface of manufactured part, which results in reduced surface roughness, hardened surface and reduced internal stress. In this Diploma, I tried to estimate the most appropriate parameters for this operation. The results have shown noticeable improvements in roughness and hardness of material surface. Problems occurred because of the small memory of robot, the robot tolerances and calibration of the tool and the workpiece. The process of Machine Hammer Peening reduces the time needed for hand processing of products. mikrokovanje utrjevanje površine glajenje površine machine hammer peening surface hardening surface smoothing true true false [J.
