  2. 1. Tool Life and Cutting Data Modelling in Metal Cutting : Testing, Modelling and Cost Performance

    Author : Daniel Johansson; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metal cutting; tool life; tool wear; cutting data; process cost; Colding model; part cost;

    Abstract : One of the most important production processes in industry is metal cutting. If a product is not a machined metal part, it is likely that the mould, die and tools used to produce the product or parts of the product are machined. READ MORE

  4. 2. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

    Author : Yujing Li; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

    Abstract : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. READ MORE

  5. 3. Tooling and processing for efficient and high tolerance prepreg composite manufacturing

    Author : Tommy Grankäll; Malin Åkermo; Per Hallander; Simon Bickerton; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tooling; Composite Manufacturing; Mould; Cure tool; Hot-forming; Compensation; Moisture; Shape distortion; Flyg- och rymdteknik; Aerospace Engineering;

    Abstract : Composite use is normally motivated in aircraft design by improved weight-specific mechanical properties as compared to metals. However, fatigue and dielectric properties may also be critical for material selection. READ MORE

  6. 4. The Metallurgical Aspects of Machinability in Prehardened Mould Steels

    Author : Seyyed Mohammad Hamed Hoseiny; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bainitic structure; Tool Life; Cutting Temperature; Cutting Force; Machinability; Microstructure; Tempered Martensite; Plastic Mould Steels;

    Abstract : High economical efficiency obtained by utilizing prehardened mould steels in plastic mould making has increased the usage of these types of steels to a great extent. Generally, prehardened mould steels are applied for large moulds and moulds for moderate production runs, and one of the advantages of using this type of steel is that no heat treatment is necessary for putting the mould in use.

  7. 5. Influence of Microstructure on the Machinability of Prehardened Mould Steels

    Author : Seyyed Mohammad Hamed Hoseiny; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prehardened mould steels; Milling; Drilling; Turning; Tool life; Machinability;

    Abstract : Mould steels are mainly employed in moulding of plastic products, and also some metals withlow melting temperature such as magnesium alloys. The ever-growing usage of plastics in theindustry, especially the automotive industry, and in everyday life, has increased the utilizationof mould steels. READ MORE
