In the master thesis, we evaluate the design of a oriented insert used for the processing of tool inserts, where the machining is carried out with an abrasive flow. In the theoretical part, we first describe the different basic 3D printing technologies and the Onyx polymer filament. We then go on to present the abrasive flow machining (AFM) process and equipment used to measure the surface topography. In the experimental part, several different experiments were carried out where the abrasive flow machining of tool inserts was analysed using the contact gauge. Based on the results, the design of the 3D printed oriented insert was adjusted to achieve the most uniform surface treatment. The final tool insert was also compared for wear rate and roughness across the surface using a 3D optical measuring equipment. A cost analysis between manual and machine polishing of the tool insert was also carried out. In this work we show that the use of a oriented insert in abrasive machining can provide almost uniform machining over the entire surface of the tool insert. A significantly shorter polishing time is also achieved, which has an impact on the final cost of the product.
