  2. 1. Process planning for precision manufacturing : An approach based on methodological studies

    Author : Mats Bagge; Bengt Lindberg; Anders Kinnander; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; precision manufacturing; machining; tolerance chain analysis; process behaviour; process performance; process capability; in-process workpiece.; Production Engineering; Industriell produktion;

    Abstract : Process planning is a task comprising a broad range of activities to design and develop an appropriate manufacturing process for producing a part. Interpretation of the part design, selection of manufacturing processes, definition of operations, operation sequences, machining datums, geometrical dimensions and tolerances are some common activities associated with the task.

  5. 3. A Computational Framework for Control of Machining System Capability : From Formulation to Implementation

    Author : Andreas Archenti; Cornel Mihai Nicolescu; Mamoru Mitsuishi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining system; Stability; Statistical Dynamics; Elastic Linked System ELS ; Operational Dynamic Parameters ODP ; Loaded Double Ball Bar LDBB ; Virtual Machining System Engine VMSE ; Contactless Excitation and Response System CERS .; SRA - Production; SRA - Produktion;

    Abstract : Comprehensive knowledge and information about the static and dynamic behaviour of machine tools, cutting processes and their interaction is essential for machining system design, simulation, control and robust operation in safe conditions. The very complex system of a machine tool, fixture and cutting tools during the machining of a part is almost impossible to model analytically with sufficient accuracy. READ MORE

  6. 4. Controlling the dynamic characteristics of machining systems through consciously designed joint interfaces

    Author : Constantinos Frangoudis; Cornel Mihai Nicolescu; Amir Rashid; Bulent Tasdelent; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production; machine tool; machining system control; joint interfaces; JIM; stiffness; damping; vibrations; machining process; milling; turning; deflections; accuracy; dynamic response;

    Abstract : The precision of machining systems is ever increasing in order to keep up with components’ accuracy requirements. At the same time product variants areincreasing and order quantities are decreasing, which introduces high demands on the capability of machining systems. READ MORE

  7. 5. Model-Based Investigation of Machining Systems Characteristics : Static and Dynamic Stability Analysis

    Author : Andreas Archenti; Mihai Nicolescu; Amir Rashid; KTH; []
    Keywords : Machining systems; modelling; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The increasing demands for precision and efficiency in machining call for new control strategies for machining systems based on the identification of static and dynamic characteristics under operational conditions. By considering the machining system as a closed-loop system consisting of a machine tool structure and a machining process, the join system characteristics can be analyzed. READ MORE
