  1. 1. Tribology at the Cutting Edge A Study of Material Transfer and Damage Mechanisms in Metal Cutting

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Julia Lundberg Gerth; Uppsala universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; Metal cutting; Gear hobbing; Wear; Coating; Residual stress; Material transfer; Steel; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : The vision of this thesis is to improve the metal cutting process, with emphasis on the cutting tool, to enable stable and economical industrial production while using expensive tools such as hobs. The aim is to increase the tribological understanding of the mechanisms operating at a cutting edge and of how these can be controlled using different tool parameters. READ MORE

  2. 2. Tool Life and Cutting Data Modelling in Metal Cutting : Testing, Modelling and Cost Performance

    University dissertation from Department of Mechanical Engineering, Lund University

    Author : Daniel Johansson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metal cutting; tool life; tool wear; cutting data; process cost; Colding model; part cost;

    Abstract : One of the most important production processes in industry is metal cutting. If a product is not a machined metal part, it is likely that the mould, die and tools used to produce the product or parts of the product are machined. READ MORE

  3. 3. Vibrations in Metal Cutting Measurement, Analysis and Reduction

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Linus Pettersson; Blekinge Tekniska Högskola.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Vibration and noise in metal cutting are ubiquitous problems in the workshop. The turning operation is one kind of metal cutting that exhibits vibration related problems. Today the industry aims at smaller tolerances in surface finish. Harder regulations in terms of the noise levels in the operator environment are also central. READ MORE

  4. 4. Numerical Modelling and Analysis of Orthogonal Metal Cutting

    University dissertation from Lund University (Media-Tryck)

    Author : Mathias Agmell; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal Cutting; Finite Element Method; Deformation Zones; Sub-surface Deformation; Tool Stress; Inverse Analysis; Kalman Filter; Minimum Chip Thickness;

    Abstract : Popular Abstract in Swedish De flesta komponenter som används i vårt samhälle har genomgått en bearbetningsprocess i något skede i sin tillverkningscykel. På grund av detta spelar de ekonomiska aspekterna av bearbetningsprocessen en viktig roll i tillverkningskostnaden. READ MORE

  5. 5. Workpiece steels protecting cutting tools from wear A study of the effects of alloying elements on material transfer and coating damage mechanisms

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Toshiharu Aiso; Uppsala universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal cutting; Steel; Cutting tools; Transfer; Coating; Sliding; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : The vision of this thesis is to improve the machinability of workpiece steels. Workpiece material frequently transfers to the cutting tools during machining, and the transfer layers then forming on the tools may give both good and bad effects on machining performance and tool life.
