Evaluation of chip formation mechanisms in the turning of sintered ZnO electro-ceramics
Jaka Dugar, Awais Ikram, Franci Pušavec
Izvirni znanstveni članek
Oznake: ZnO varistorji;optimizacija parametrov obdelave;struženje;formiranje odrezkov;ZnO varistors;machining optimization;turning;chipping;accelerometer;FFT plotting;3D topography;
The sintered zinc oxide (ZnO) electro-ceramics are a brittle class of hard-to-cut materials such that shaping them with the post-finishing operations necessitates careful handling and precision machining. The conventional machining approach using the grinding and lapping processes represents limited ...

Comparative characterization of different cutting strategies for the sintered ZnO electroceramics
Jaka Dugar, Awais Ikram, Franci Pušavec
Izvirni znanstveni članek
Oznake: ZnO;varistorji;frezanje;rezanje z vodnim curkom;varistors;machining;milling;abrasive waterjet cutting;porosity;electron microscopy;edge radius (r) profilometry;surface roughness (Sa, S10Z);topography analysis;
Sintered zinc oxide (ZnO) ceramic is a fragile and difficult-to-cut material, so finishing operations demand handling cautious and accurate surface tolerances by polishing, grinding, or machining. The conventional machining methods based on grinding and lapping offer limited productivity and high sc ...

Sustainable hybrid manufacturing of AlSi5 alloy turbine blade prototype by robotic direct energy layered deposition and subsequent milling
Jaka Dugar, Awais Ikram, Damjan Klobčar, Franci Pušavec
Izvirni znanstveni članek
Oznake: računalniško podprta proizvodnja;računalniško podprto projektiranje;hibridna predelava;robotsko frezanje;zasnova za dodajalno proizvodnjo;izdelava dodajalne tehnologije z varjenjem;computer-aided manufacturing;computer-aided design;hybrid processing;robotic milling;design for additive manufacturing;wire arc additive manufacturing;CAD;CAM;WAAM;DFAM;
Additive technologies enable the flexible production through scalable layer-by-layer fabrication of simple to intricate geometries. The existing 3D-printing technologies that use powders are often slow with controlling parameters that are difficult to optimize, restricted product sizes, and are rela ...

Spark plasma sintering as an effective texturing tool for reprocessing recycled HDDR Nd-Fe-B magnets with lossless coercivity
Awais Ikram, Muhammad Awais, Richard Stuart Sheridan, Allan Walton, Spomenka Kobe, Franci Pušavec, Kristina Žužek Rožman
Izvirni znanstveni članek
Oznake: rare earth permanent magnets;anisotropic HDDR Nd$_2$Fe$_{14}$B;recycling;spark plasma sintering;texture development;hot deformation;
The low-pressure hot-deformation methodology was applied to reprocess the nanocrystalline hydrogenation–disproportionation–desorption–recombination (HDDR) Nd-Fe-B powders from end-of-life (EOL) permanent magnets’ waste to determine the mechanism of texture development and the resultant improvement i ...
