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

    Author : Pajazit Avdovic; Industriell Produktion; []
    Keywords : 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;

    Abstract : 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). READ MORE

  3. 3. Condition Monitoring in Machining Using Internal Sensor Signals

    Author : Jari Repo; Cornel Mihai Nicolescu; Terje Lien; Terje K. Lien; Högskolan Väst; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Condition monitoring; machine tool; machining process; milling; position encoders; tool wear detection; signal analysis; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Condition monitoring of critical machine tool components and machining processes is a key factor to increase the availability of the machine tool and to achieve a more robust machining process. Any failure in the machining process and machine tool components may have negative effects on the final produced part. READ MORE

  4. 4. Adaptive Active Control of Machine-Tool Vibration in a Lathe - Analysis and Experiments

    Author : Lars Håkansson; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Metal Cutting; Lathe; Tool Vibration; Active Control; Adaptive Signal Processing; materialteknik;

    Abstract : In the turning operation the relative dynamic motion between cutting tool and workpiece, or vibration, is a frequent problem, which affects the result of the machining, and in particular, the surface finish. Tool life is also influenced by vibration. READ MORE

  5. 5. Modelling, Simulation and Optimisation of a Machine Tool

    Author : Johan Fredin; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : To be competitive in today’s global market it is of great importance that product development is done in an effective and efficient way. To enhance functionality, modern products are often so-called mechatronic systems. This puts even higher demands on the product development work due to the complexity of such products. READ MORE
