1. 16. Theoretical and experimental studies of a single tooth milling process

   Författare :Mathias Werner; Cornel Mihai Nicolescu; Lars Nyborg; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 17. Machinability Testing of Materials in Metal Cutting with Focus on Compacted Graphite Iron and Cutting Fluids

   Författare :Varun Nayyar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UTS.; Boring; Drilling; Cutting Fluid; Turning; Milling; Force; Wear; Force; Torque; Compressed air; CGI; Hardness; Tool Life; Material Properties; Chip Microstructure; Tapping;

   Sammanfattning : Due to the stringent demands for lower emission from trucks require better mechanical properties of the material to be used in the engines. Better efficiency necessitates higher peak pressure in the engines and for traditionally used material, Flake Graphite Iron (FGI), the mechanical properties starts to reach the limit of what the material can withstand.

5. 19. Numerical Modelling and Analysis of Orthogonal Metal Cutting

   Författare :Mathias Agmell; Industriell Produktion; []
   Nyckelord :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;

   Sammanfattning : Most components in use in our society have undergone a machining process at some stage within its manufacturing cycle. As a result, the economics of the machining process plays an important role in the manufacturing costs. LÄS MER

7. 20. On cutting tool resource management

   Författare :Ana Esther Bonilla Hernández; Tomas Beno; Claes Fredriksson; Leonardo De Chiffre; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAM programming; Cutting data; Lean; Manufacturing; Material Removal Rate; Optimization; Tool life; Tool utilization; Tool wear; Sustainability; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : The search for increased productivity and cost reduction in machining can be interpreted as desire to increase the Material Removal Rate, , and maximize the cutting tool utilization. The CNC process is complex and involves numerous constraints and parameters; ranging from tolerances to machinability. LÄS MER
