  1. 1. Methods and Models for Cutting Data Optimization

    Author : Sören Hägglund; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool Life; Cutting Forces; Tool Replacement Coordination; Process Cost; Tooling Cost; Cutting Data Optimization; Surface Finish; Cycle Time Balancing;

    Abstract : Traditional optimization of cutting processes refers to minimizing cost or minimizing time (minimumcost or maximum production rate). These criteria apply to the cutting speed via well-known equationsfor economic tool life and tool life for maximum production rate. Quite often speed is focused firstwhen after some suitable feed value is chosen. READ MORE

  2. 2. Mechanical Load Identification for Spontaneous Tool Failure Monitoring

    University dissertation from Department of Production and Materials Engineering, LTH, Lund University

    Author : Jinming Zhou; Lunds universitet.; Lund University.; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Monitoring; Cutting force; Identification; Cutting; Manufacturing; materialteknik;

    Abstract : The problem of spontaneous cutting tool failure, such as tool chipping and breakage, is becoming more and more important in the manufacturing technology. The sponataneous tool failure is usually associated with the stresses subjected on the tool during a metal cutting process. READ MORE

  3. 3. Investigation on the Influence of Nodularity in Machining of Compacted Graphite Iron (CGI)

    University dissertation from Department of Production and Materials Engineering, LTH, Lund University

    Author : Gustav Grenmyr; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compacted Graphite Iron CGI ; cutting forces; wear mechanisms; tool wear; nodularity; tool temperature; cutting temperature;

    Abstract : Stringency of environmental legislation on emission rates and increasing vehicle performance requirements are pushing the automotive and heavy truck industries to find new solutions for their diesel engines. Two potential opportunities to address these challenges involve increased combustion pressure to obtain more efficient combustion or reducing the weight of the engine. READ MORE

  4. 4. Characterization of White Layers induced by Hard Turning of AISI 52100 Steel

    University dissertation from Department of Production and Materials Engineering, LTH, Lund University

    Author : Seyed Hosseini; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; white layer; hard turning; IR-pyrometer; nano-sized grains; martensite; cutting temperature; bainite; cubic boron nitride; residual stress; retained austenite; cutting forces;

    Abstract : Hard turning is a machining process applied to metallic materials with hardness above 45 HRC. The process offers high production flexibility and sustainable manufacturing since it allows performing both rough and finishing machining of complex geometries in one single setup. READ MORE

  5. 5. Investigation of Forces and Contact Area for Modelling Turning Processes

    University dissertation from Stockholm : KTH

    Author : Ove Bayard; KTH.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Modelling; turning processes; cutting forces; contact length; Quick Stop Device; QSD; simulation programs; FEM; predictive models.; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis is focused on an investigation of forces andcontact area for modelling turning processes. The primary taskin short term research has been to take a first steptowards animproved model of the cutting process. READ MORE
