  1. 31. Wear Mechanisms in Cutting Tools for Machining Applications : Interfacial Phenomena, Characterization, and Relation to Performance

    Författare :Rebecka Lindvall; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Metal cutting technology plays an important role in the automotive and aeronautic sectors, both of whichare important for the Swedish economy. Both make use of traditional grey cast iron and difficult-to-machine materials like titanium alloys and compacted graphite iron. LÄS MER

  3. 32. Machining Monitoring and Control : Based on Parametric Modelling

    Författare :Mats Bejhem; KTH; []
    Nyckelord :Machining Control; tool condition monitoring; in-process dynamic stability monitoring and control; optimisation of cutting conditions; MC; DSP; TCM; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The objective of this work was the development of aMachining Control prototype system for turning, whichintegrates three fundamental aspects of Machining Controltechnology: Monitoring, Control and Optimisation. MachiningControl refers to the detection and automatic handling ofdisturbances in machining processes. LÄS MER

  4. 33. Chatter stability of turning and milling with process damping

    Författare :Mahdi Eynian; Yusuf Altintas; Canada The University of British Columbia The Faculty of Graduate Studies (Mechanical Engineering); []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The prediction of chatter instability in machining steel and thermal-resistant alloys at low ‎cutting speeds has been difficult due to unknown process damping contributed by the ‎contact mechanism between tool flank and wavy surface finish. This thesis presents ‎modeling and measurement of process damping coefficients, and the prediction of chatter ‎stability limits for turning and milling operations at low cutting speeds. LÄS MER

  5. 34. Regenerative Chatter Vibration in Indexable Drills : Modeling and Simulation

    Författare :Amir Parsian; Tomas Beno; Mahdi Eynian; Martin Magnevall; Erhan Budak; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound; Vibrations; Drill; Indexable; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : An indexable insert drill is a drill which uses cutting inserts to make holes. Undesirable sound generated by this type of drill has always been considered as a problem in workshops. The focus of this thesis is to investigate the mechanism behind these vibrations, to model it and to provide guidelines for reducing the sound in future drill designs. LÄS MER

  7. 35. Dynamics of Torsional and Axial Vibrations in Indexable Drills

    Författare :Amir Parsian; Tomas Beno; Mahdi Eynian; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drilling Dynamics; Chatter Vibrations; Indexable Drills; Simulation; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Drilling is widely used in manufacturing of products which need holes, for example for fluid channels, screws or pins. Depending on application, workpiece material, cutting parameters and economic considerations, different types of drills are employed. Indexable insert drills are types of drills which facilitate inserts to make holes. LÄS MER
