  1. 1. Advances in High Porductivity - High Quality Machining

    Författare :Marcel Escursell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexibility; Quality; Machining; Productivity;

    Sammanfattning : Quality, productivity and flexibility are vital factors in todays machining industry in order to remain competitive. Nowadays, finished products not only have to be produced within specific tolerance limits, but they also have to posses high standards in terms of surface integrity, i.e. LÄS MER

  3. 2. Machining of Some Difficult-to-Cut Materials with Rotary Cutting Tools

    Författare :Tero Stjernstoft; KTH; []
    Nyckelord :Difficult-to-Cut material; Metal Matrix Composite MMC ; Machining; Machinability; Rotary Cutting Tool; Acoustic Emission;

    Sammanfattning : Automobile and aero industries have an increasing interestin materials with improved mechanical properties. However, manyof these new materials are classified as difficult-to-cut withconventional tools. It is obvious that tools, cutting processesand cutting models has to be devel-oped parallel to materialsscience. LÄS MER

  4. 3. Machinability variations in Alloy 718 —With focus on machining of turbine components

    Författare :Pajazit Avdovic; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polar diagram; flank wear; ceramic tool; variation in material; tool wear; tool life; machinability; Inconel; Alloy 718; Machining; notch wear;

    Sammanfattning : In gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). LÄS MER

  7. 5. Part Quality Prediction and Variation Reduction in Multistage Machining Processes Based on Skin Model Shapes

    Författare :Filmon Yacob; Daniel Semere; Sophie Gröger; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining simulation; model-based prediction; variation propagation; variation source identification; variation compensation; tolerance analysis; Octree; anomaly detection; quaternion; dual quaternion; Plücker coordinate.; Maskinbearbetningssimulering; modellbaseradförutsägelse; variationsspridning; variationskällidentifiering; variationskompensation; toleransanalys; Octree; dual quaternions; Plücker-koordinat.; Production Engineering; Industriell produktion;

    Sammanfattning : All manufacturing processes inevitably induce variations into manufactured parts that may result in nonconformance. Nonconforming parts incur costs due to the additional process required for rework or scrap loss. Hence, methodical efforts to reduce these variations are necessary for competitive manufacturing.
