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

   Author : Toshiharu Aiso; Staffan Jacobson; Urban Wiklund; Staffan Söderberg; Uppsala universitet; []
   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.

5. 3. Methods and Models for Cutting Data Optimization

   Author : Sören Hägglund; Chalmers tekniska högskola; []
   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

6. 4. Laser cutting and piercing: Experimental and theoretical investigation

   Author : Jetro Pocorni; Alexander F. H. Kaplan; John Powell; Jan Frostevarg; William O'Neill; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser cutting; laser piercing; efficiency; fibre laser; CO2 laser; high speed imaging; Produktionsutveckling; Manufacturing Systems Engineering; Maskinteknik;

   Abstract : This thesis concerns experimental investigations of laser cutting and piercing, with theoretical and practical discussions of the results. The thesis is made up of an introduction to laser cutting and six scientific Papers. READ MORE

7. 5. Theoretical and experimental studies of a single tooth milling process

   Author : Mathias Werner; Cornel Mihai Nicolescu; Lars Nyborg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hobbing; single tooth milling test; TiN; High speed Steel HSS ; wear mechanisms; cutting force; cutting edge preparation; tool surface preparation; FEM cutting model;

   Abstract : The industrial development of metal cutting processes in gear manufacturing aims at continuously increasing productivity, including increased tool reliability. Basically, the parameters that have an influence on the cutting processes should be known and possible to control.Gear manufacturing is highly important for the automotive industry. READ MORE
