2. 21. Edge Geometry Effects on Entry Phase by Forces and Vibrations

   Author : Adnan Agic; Tomas Beno; Jan-Eric Ståhl; Mahdi Eynian; T.H.C. Childs; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Entry; Cutting force; Cutting edge geometry; Acceleration; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : Intermittent machining is in general strongly related to the large impacts in the entry phase and related vibrations. The influence of the impact forces and vibrations on the cutting process is dependent on workpiece material, structural properties of the tool-workpiece system, cutting edge geometries and cutting parameters.

5. 23. Machining properties of wood : Tool wear, cutting force and tensioning of blades

   Author : Luis Cristovao; Frieder Scholz; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Abstract : Cutting processes, in general, and wood cutting processes, in particular, are complex to explain and describe with many influencing factors. Wood, in contrast to man-made fabricated materials, is not a homogenous and distinct material, but a multifaceted and nonhomogeneous biological material. READ MORE

6. 24. Haptic and visual simulation of material cutting process : a study focused on bone surgery and the use of simulators for education and training

   Author : Magnus G. Eriksson; Jan Wikander; Ingela Nyström; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; surgical simulation; virtual reality; haptic feedback; surgical training; medical simulators; metrics; 3D visualization; Medical technology; Medicinsk teknik;

   Abstract : A prototype of a haptic and virtual reality simulator has been developed for simulation of the bone milling and material removal process occurring in several operations, e.g. temporal bone surgery or dental milling. The milling phase of an operation is difficult, safety critical and very time consuming. READ MORE

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

   Author : Amir Malakizadi; Chalmers tekniska högskola; []
   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.
