RISModelling, Identification and Control of Thermal Deformation of Machine Tool Structures, Part 1: Concept of Generalized Modelling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the increasing demand for improved machining accuracy in recent years, the problem of thermal deformation of machine tool structures is becoming more critical than ever. In spite of the ...
Modelling, Identification and Control of Thermal Deformation of Machine Tool Structures, Part 4: A Multi-Variable Closed-Loop Control System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A multi-variable closed-loop control system is proposed to compensate for the thermal deformation of machine tool structures. The control system recognizes the fact the relative thermal displacement ...
Modelling, Identification and Control of Thermal Deformation of Machine Tool Structures, Part 5: Experimental Verification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Machining accuracy is more often governed by thermal deformation of the machine tool structure than by static stiffness and dynamic rigidity. Since thermally induced errors cannot completely be ...
Modelling, Identification and Control of Thermal Deformation of Machine Tool Structures, Part 3: Real-Time Estimation of Heat Sources
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compensation of thermal deformation of machine tools requires real-time estimation of the heat input to the structure in order to fully describe its thermoelastic response. Available solutions ...
Control-Oriented Modeling of Thermal Deformation of Machine Tools Based on Inverse Solution of Time-Variant Thermal Loads with Delayed Response
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the new emerging technologies of high performance machining and the increasing demand for improved machining accuracy in recent years, the problem of thermal deformation of machine tool ...
Modelling, Identification and Control of Thermal Deformation of Machine Tool Structures, Part 2: Generalized Transfer Functions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the ever increasing demand for higher machining accuracy at lower cost, thermal deformation of machine tool structures has to be minimized at the design stage, and compensated for during ...
Development of an Apparatus to Produce Fractures From Short-Duration High-Impulse Loading With an Application in the Lower Leg
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Axial loading of the lower leg during impact events can cause significant fractures of the tibia. The magnitude of lower leg axial loading that occurs during short-duration high-impulse events, ...
Rolling Resistance Measurement and Model Development
Publisher: American Society of Civil Engineers
Abstract: There is an increased focus worldwide on understanding and modeling rolling resistance because reducing the rolling resistance by just a few percent will lead to substantial energy savings. This paper reviews the state of ...
