1. 1. Jämförelse av torr bearbetning och minimalsmörjningseffekter på fräsning av austenitiskt rostfritt stål

   M1-uppsats, Högskolan i Gävle/Maskinteknik

   Författare :Adam Norell; Darav Hajo; [2023]
   Nyckelord :MQL; milling; stainless steel; tool wear; MQL; fräsning; rostfritt stål; verktygsförslitning;

   Sammanfattning : Fräsning och annan intermittent skärande bearbetning ger upphov till termisk utmattning av skärverktyg. Problemet med termiska sprickor blir större vid bearbetning av värmehållfasta material som austenitiskt rostfritt stål eftersom värmeväxlingarna i skärverktyget blir mer extrema. LÄS MER

   Sammanfattning : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. LÄS MER

4. 3. Development of a 3D Ring Dynamics Model For a Heavy-Duty Piston Ring-Pack

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Parthasri Akurati; Karan Kumar; [2021]
   Nyckelord :3D ring model; Flank wear; Oil consumption; Piston ring dynamics;

   Sammanfattning : With the increasing restrictions in emission legislations, the automotive industry aims to improve the efficiency of the lubricating system and to decrease fuel consumption. In the power cylinder unit (PCU), the piston rings are the major contributor to these consumptions. LÄS MER

5. 4. Finite element analysis of the effects of theCu:CNx nano-composite multilayer coating onto the improvement of cutting tool life

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Yang Liu; Rui Wang; [2021]
   Nyckelord :;

   Sammanfattning : To verify the effects of applying the shim with nanostructured composite damping coating onto the improvement of cutting tool life, the thesis studies two related aspects, the experiment and finite element software simulation. The experiment part mainly discusses the methods of designing the experiment process and verifying the damping vibration effectiveness of the coated shim. LÄS MER

7. 5. Method to assess machinability of engineering steels using coated carbide tools

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

   Författare :Petra Hedberg; [2021]
   Nyckelord :Machinability; tool wear; coated carbide; non-metallic inclusions; Ca-treated; steel; 42CrMo4;

   Sammanfattning : In this master thesis, performed at Ovako Group R&D (Hofors) a new machining test method for ranking heats of calcium-treated steels, M-Steels, has been proposed.  A total of six different heats of 42CrMo4-M steel in the quenched-and-tempered (Q+T) condition were tested. LÄS MER
