  1. 1. Optimisation of Machining Operations by means of Finite Element Method and Tailored Experiments

    Author : Amir Malakizadi; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Usui wear model; Bi-metals; Flank wear; Johnson-Cook; Inverse identification; Metal cutting; Thermal fatigue cracking; Wear modelling; Finite element method; Response surface methodology;

    Abstract : Traditionally, costly experimental procedures have been followed in industry to optimise the machining operations to secure the maximum efficiency in production line, while the functional requirements of the machined surfaces are fulfilled. In recent years, development of robust numerical techniques such as Finite Element Method (FEM) and advances in computing capacity of computers have made it possible to simulate the machining operations under operational conditions.

  2. 2. Optimisation of Machining Operations by means of Finite Element Method and Tailored Experiments

    Author : Amir Malakizadi; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Response Surface Methodology; inverse identification; bi-metals; flank wear; Wear modelling; thermal fatigue cracking; Finite Element Method; Usui’s model; metal cutting; Johnson-Cook;

    Abstract : The experimental approach has long been the main method to investigate the responses associated with metal cutting process such as cutting forces and temperatures and also to optimise the machining operations to accomplish higher productivity. In recent years, with advances in computing power of computers along with development of robust numerical methods such as Finite Element Method (FEM), it has been possible to simulate different machining process under operational conditions.
