  1. 1. Skäreggars spontanhaverier

    Författare :Jan-Eric Ståhl; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chipping; edge; cracking; deterioration; Cutting; rupture;

    Sammanfattning : Disturbances in production caused by rupture, cracking and chipping of tool edges are only studied to a limited extent in comparison with the effect of the cutting edge wear. These phenomena are of increasing importance when automation in production is considered. LÄS MER

  3. 2. Analysis of entry phase in intermittent machining

    Författare :Adnan Agic; Tomas Beno; Jan-Eric Ståhl; Mahdi Eynian; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Entry; Cutting force; Cutting edge geometry; Acceleration; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Cutting forces and vibrations are essential parameters in the assessment of a cutting process. As the energy consumption in the machining process is directly affected by the magnitude of the cutting forces it is of vital importance to design cutting edges and select process conditions that will maintain high tool performance through reduced energy consumption.

  4. 3. Edge Geometry Effects on Entry Phase by Forces and Vibrations

    Författare :Adnan Agic; Tomas Beno; Jan-Eric Ståhl; Mahdi Eynian; T.H.C. Childs; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Entry; Cutting force; Cutting edge geometry; Acceleration; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Intermittent machining is in general strongly related to the large impacts in the entry phase and related vibrations. The influence of the impact forces and vibrations on the cutting process is dependent on workpiece material, structural properties of the tool-workpiece system, cutting edge geometries and cutting parameters.
