1. 16. Theoretical and experimental study of tooling systems : passive control of machining vibration

   Författare :Lorenzo Daghini; Cornel Mihai Nicolescu; Tomas Beno; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial engineering and economy; Industriell teknik och ekonomi;

   Sammanfattning : Vibration control has been and still remains a subject of primary importance in modern manufacturing industry. To be able to remove high volumes of material in shorter time as well as to be able to get the right quality of the parts at the first time are goals that many shops would like to achieve. LÄS MER

3. 17. Machinability variations in alloy 718 turbine components

   Författare :Pajazit Avdovic; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variation in tool; hardness; Machining; flank wear; notch wear; alloy 718; grain size; instability; variation in material;

   Sammanfattning : Machinability Variations in Alloy 718 Turbine Components PAJAZIT AVDOVIC Department of Materials and Manufacturing TechnologyChalmers University of Technology AbstractAlloy 718 has a reputation for being very troublesome during the cutting process. It was suspected that this material was too hard and having too fine grain size and that these characteristics caused damage to cutting tools during processing. LÄS MER

4. 18. Environmental, Resource and Health Assessments of Hard Materials and Material Substitution: The Cases of Cemented Carbide and Polycrystalline Diamond

   Författare :Anna Furberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Life cycle assessment; polycrystalline diamond; disability-adjusted life years; material flow analysis; machining tools; cemented carbide;

   Sammanfattning : The conventional hard material used in manufacturing industry, cemented carbide (WC-Co), mainly consists of the geochemically scarce elements tungsten and cobalt. This use of scarce resources could potentially be avoided by a material substitution to the more abundant and largely carbon-based material polycrystalline diamond (PCD). LÄS MER

5. 19. Model driven process planning for machining : Theory, application and improved information standards for efficient product realization

   Författare :Mikael Hedlind; Torsten Kjellberg; Fumihiko Kimura; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; modeling; ISO 10303; CADCAM; kinematics; Beredning; modellering; ISO 10303; CADCAM; kinematik; SRA - Production; SRA - Produktion;

   Sammanfattning : Model driven process planning is a methodology that emphasizes the application of models to create, represent and use information of products, processes and resources. Industry today stores information in a fragmented manner, mainly document centered with the consequence of data duplication requiring comprehensive data management and maintenance. LÄS MER

7. 20. An Analysis of Machining System Capability and Its Link with Machined Component Quality

   Författare :Tomas Österlind; Cornel-Mihai Nicolescu; Tatar Kourosh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining System Capability; Elastic Linked System; Spiral Bevel Gear Face Milling; SRA - Production; SRA - Produktion;

   Sammanfattning : Machining components out of tolerances is of no use in competitiveproduction. The machining system sets the limitations of dimensionalaccuracy and surface quality of a machined component. The capabilityof the machining system describes these limits in terms of specifiedvalues.
