1. 11. Dynamiskt belastade tribologiska system under plastisk formning, del II --- analyserade genom akustisk emission

   Författare :Thomas Skåre; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; vacuum technology; hydraulics; Mechanical engineering; supervision; wear; waves; vibrations; tribology; surfaces; stick-slip; sliding; sheet metal; quality check; plastic forming; monitoring; galling; machining; deep drawing; friction; cracking; contact surfaces; Acoustic emission AE ; contact pressure; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; Material technology; Materiallära; materialteknik; Production technology; Produktionsteknik;

   Sammanfattning : The dynamic friction process and contact surface between tool and working material in a plastic forming process is hard to describe in mathematical form and hard to monitor and control in real time. High production speed and highly optimised forming operations result in great demands on the control equipment. LÄS MER

3. 12. 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

4. 13. Model-Based Investigation of Machining Systems Characteristics : Static and Dynamic Stability Analysis

   Författare :Andreas Archenti; Mihai Nicolescu; Amir Rashid; KTH; []
   Nyckelord :Machining systems; modelling; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The increasing demands for precision and efficiency in machining call for new control strategies for machining systems based on the identification of static and dynamic characteristics under operational conditions. By considering the machining system as a closed-loop system consisting of a machine tool structure and a machining process, the join system characteristics can be analyzed. LÄS MER

5. 14. Condition Monitoring in Machining Using Internal Sensor Signals

   Författare :Jari Repo; Cornel Mihai Nicolescu; Terje Lien; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Condition monitoring; machine tool; machining process; milling; position encoders; tool wear detection; signal analysis; Manufacturing and materials engineering; Produktions- och materialteknik;

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

7. 15. Theoretical and experimental study of tooling systems : passive control of machining vibration

   Författare :Lorenzo Daghini; Cornel Mihai Nicolescu; Tomas Beno; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial engineering and economy; Industriell teknik och ekonomi;

   Sammanfattning : Vibration control has been and still remains a subject of primary importance in modern manufacturing industry. To be able to remove high volumes of material in shorter time as well as to be able to get the right quality of the parts at the first time are goals that many shops would like to achieve. LÄS MER
