Strategije obdelave 3D tiskanega implantata kolka z robotiziranim udarnim utrjevanjem površine

Zager, Eric (author), Pušavec, Franci (mentor)

V nalogi obravnavamo robotizirano naknadno obdelavo površine aditivno izdelanega vzorca kolčnega implantata iz jekla AISI 316L s tehnologijo udarnega utrjevanja. Zasnovali smo vpenjalno pripravo in izvedli obdelavo z robotskim sistemom pri različnih procesnih parametrih. Sile obdelave smo izmerili z dinamometrom, površinsko topografijo pa smo ovrednotili z optičnim merilnim sistemom. Rezultati so pokazali, da je mogoče doseči ugodne lastnosti površinske topografije za obravnavano aplikacijo, pri čemer imata največji vpliv na površinske značilnosti razmik med udarci in geometrija orodne konice.

• Title: Processing strategies for a 3D-printed hip implant using robotic machine hammer peening

Abstract

This work addresses robotic post-processing of the surface of an additively manufactured hip implant sample made of AISI 316L steel using hammer peening. We designed a clamping fixture and carried out the treatment using a robotic system using various process parameters. Processing forces were measured using a dynamometer, and surface topography was characterized using an optical measuring system. The results showed that favorable surface topography properties can be achieved for the application in question, with the spacing between impacts and the tool tip geometry having the greatest influence on the surface charactheristics.
