2. 1. 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

4. 2. Joint Interface Effects on Machining System Vibration

   Author : Qilin Fu; Cornel-Mihai Nicolescu; Tomas Beno; KTH; []
   Keywords : Joint Interface; Vibration; Damping; Chatter; Machining; Carbon NanoComposite; PECVD; HiPIMS; SRA - Production; SRA - Produktion; Järnvägsgruppen - Ljud och vibrationer; Järnvägsgruppen - Ljud och vibrationer;

   Abstract : Vibration problems are still the major constraint in modern machining processes that seek higher material removal rate, shorter process time, longer tool life and better product quality. Depending on the process, the weaker structure element can be the tool/tool holder, workpiece/fixture or both. READ MORE

5. 3. Estimation of Machining System Dynamic Properties - Measurement and Modelling

   Author : Tomas Österlind; Andreas Archenti; Mihai Nicolescu; Leif Kari; Amir Rashid; Thomas Abrahamsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining system; Operational dynamic parameters; Displacement map; Contactless excitation and response system; SRA - Production; SRA - Produktion; Production Engineering; Industriell produktion;

   Abstract : Dynamic characteristics of machining systems are analysed for improved understanding of both structural and process properties. The thesis stresses the use of testing methods under operational like conditions as these are more representative of closed loop systems, such as machining systems, as compared to conventional testing methods.

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

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

   Abstract : 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.
