  2. 6. Machining Monitoring and Control : Based on Parametric Modelling

    Author : Mats Bejhem; KTH; []
    Keywords : Machining Control; tool condition monitoring; in-process dynamic stability monitoring and control; optimisation of cutting conditions; MC; DSP; TCM; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The objective of this work was the development of aMachining Control prototype system for turning, whichintegrates three fundamental aspects of Machining Controltechnology: Monitoring, Control and Optimisation. MachiningControl refers to the detection and automatic handling ofdisturbances in machining processes. READ MORE

  4. 7. Improving Machining System Performance through designed-in Damping : Modelling, Analysis and Design Solutions

    Author : Lorenzo Daghini; Cornel Mihai Nicolescu; Miroslav Píška; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining performance; Cutting stability; Passive damping; High Damping Interface; Boring bar; Turret; SRA - Production; SRA - Produktion;

    Abstract : With advances in material technology, allowing, for instance, engines to withstand higher combustion pressure and consequently improving performance, comes challenges to productivity. These materials are, in fact, more difficult to machine with regards to tool wear and especially machine tool stability. READ MORE

  5. 8. Control Strategies for Machining with Industrial Robots

    Author : Olof Sörnmo; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Robots; Machining; Control;

    Abstract : This thesis presents methods for improving machining with industrial robots using control, with focus on increasing positioning accuracy and controlling feed rate. The strong process forces arising during high-speed machining operations, combined with the limited stiffness of industrial robots, have hampered the usage of industrial robots in high-end machining tasks.

  7. 10. 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
