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

    Author : Julia Lundberg Gerth; Urban Wiklund; Uppsala universitet; []
    Keywords : 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

  4. 2. FE-Simulation of Metal Cutting Processes

    Author : Ahmet Semih Ertürk; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inverse identification; Machine learning; Metal cutting; Finite element method; Heat transfer; Machining;

    Abstract : Machining a new component or a new material requires the selection of the cutting conditions, the tool material and the tool geometry. The selections should be also optimized for the existing components and materials to improve the quality of the produced components and reduce the cost of production. READ MORE

  5. 3. FE-Simulation of Metal Cutting Processes

    Author : Ahmet Semih Ertürk; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal cutting; Ductile fracture; Gradient damage; Finite element method; Turning; Machining; Inverse identification;

    Abstract : This thesis deals with the finite element (FE) simulation of machining processes. Realistic simulation of metal cutting processes enables a more resource-efficient machinability assessment for a given material in terms of cutting forces, chip shape and tool wear at different ranges of cutting conditions.

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

    Author : Daniel Johansson; Industriell Produktion; []
    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

  7. 5. Vibrations in Metal Cutting : Measurement, Analysis and Reduction

    Author : Linus Pettersson; []
    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
