1. 6. Machinability variations in Alloy 718 —With focus on machining of turbine components

   Författare :Pajazit Avdovic; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polar diagram; flank wear; ceramic tool; variation in material; tool wear; tool life; machinability; Inconel; Alloy 718; Machining; notch wear;

   Sammanfattning : In gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). LÄS MER

3. 7. Condition monitoring of machine tools and machining processes using internal sensor signals

   Författare :Jari Repo; Mihai Nicolescu; Dragos Axiente; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; condition monitoring; machine tool; machining process; milling; position encoders; signal analysis; Mechanical engineering; Maskinteknik; Materials science; Manufacturing and materials engineering;

   Sammanfattning : Condition monitoring of critical machine tool components and machining processes is a key factor to increase the availability of the machine tool and achieving a more robust machining process. Failures in the machining process and machine tool components may also have negative effects on the final produced part. LÄS MER

4. 8. A Computational Framework for Control of Machining System Capability : From Formulation to Implementation

   Författare :Andreas Archenti; Cornel Mihai Nicolescu; Mamoru Mitsuishi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining system; Stability; Statistical Dynamics; Elastic Linked System ELS ; Operational Dynamic Parameters ODP ; Loaded Double Ball Bar LDBB ; Virtual Machining System Engine VMSE ; Contactless Excitation and Response System CERS .; SRA - Production; SRA - Produktion;

   Sammanfattning : Comprehensive knowledge and information about the static and dynamic behaviour of machine tools, cutting processes and their interaction is essential for machining system design, simulation, control and robust operation in safe conditions. The very complex system of a machine tool, fixture and cutting tools during the machining of a part is almost impossible to model analytically with sufficient accuracy. LÄS MER

5. 9. Capability in machining systems

   Författare :Annika Larsson; KTH; []
   Nyckelord :;

   Sammanfattning : The vehicle industry has derived a vision of simulatingmachining systems and their cutting processes with accuracy andcapability indices as a result. The accuracy of machined partsis the result of properties and characteristics of the totalmachining system and its environment. LÄS MER

7. 10. Machining properties of wood : Tool wear, cutting force and tensioning of blades

   Författare :Luis Cristovao; Frieder Scholz; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Sammanfattning : Cutting processes, in general, and wood cutting processes, in particular, are complex to explain and describe with many influencing factors. Wood, in contrast to man-made fabricated materials, is not a homogenous and distinct material, but a multifaceted and nonhomogeneous biological material. LÄS MER
