Book Synopsis On the Use of Potential Theory for Thermal Modeling in Metal Cutting by : Matthias Brockmann
Download or read book On the Use of Potential Theory for Thermal Modeling in Metal Cutting written by Matthias Brockmann and published by Apprimus Wissenschaftsverlag. This book was released on 2016-01-20 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolving temperature distributions during metal cutting are of major significance. Present analytical models are not capable to predict temperature fields to a sufficient degree. This lack of model validity is caused by the limited mathematical approaches. The present thesis deals with the development of methodologies for thermal modeling based on a class of complex functions termed potential functions. This approach has never been used before for metal cutting applications.

This book was released on 2018-12-21 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of the current work was the analysis of temperatures in the milling process in order to understand causal and statistical relationships between process parameters and thermal state variables. The first step included fundamental empirical investigations in the form of orthogonal cuts in order to estimate the heat partitioning depending on the process parameters.

Book Synopsis Thermo-energetic Design of Machine Tools by : Knut Großmann
Download or read book Thermo-energetic Design of Machine Tools written by Knut Großmann and published by Springer. This book was released on 2014-11-06 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The approach to the solution within the CRC/TR 96 financed by the German Research Foundation DFG aims at measures that will allow manufacturing accuracy to be maintained under thermally unstable conditions with increased productivity, without an additional demand for energy for tempering. The challenge of research in the CRC/TR 96 derives from the attempt to satisfy the conflicting goals of reducing energy consumption and increasing accuracy and productivity in machining. In the current research performed in 19 subprojects within the scope of the CRC/TR 96, correction and compensation solutions that influence the thermo-elastic machine tool behaviour efficiently and are oriented along the thermo-elastic functional chain are explored and implemented. As part of this general objective, the following issues must be researched and engineered in an interdisciplinary setting and brought together into useful overall solutions: 1. Providing the modelling fundamentals to calculate the heat fluxes and the resulting thermo-elastic deformations in a comprehensive manner, 2. Mapping of the structural variability as a result of the relative movement inside the machine tool, 3. Providing the tools for an efficient adjustment of parameters that vary greatly in time and space by means of parameter identification methods as a prerequisite for correction and compensation solutions, 4. Engineering and demonstrating solutions to control-integrated correction of thermo-elastic errors by an inverse position setpoint compensation of the error at the TCP, 5. Engineering and demonstrating solutions based on the material properties to compensate for thermo-elastic effects through a homogeneous propagation of the temperature field, as well as reducing and smoothing the distribution of heat dissipated in supporting structures, 6. Developing metrological fundamentals to record the thermo-elastic errors in special structural areas of machine tools, 7. Engineering a methodological approach to simultaneous and complex evaluation of the CRC/TR 96 solutions, referring to their impact on product quality, production rate, energy consumption and machine tool costs

Book Synopsis Modeling the Material Behavior under Metal Cutting Conditions by : Marvin Hardt
Download or read book Modeling the Material Behavior under Metal Cutting Conditions written by Marvin Hardt and published by Apprimus Wissenschaftsverlag. This book was released on 2022-03-16 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific goal of the present work was to model the workpiece material behavior of steels in the metal cutting process depending on the occurring thermo-mechanical loads. The results of this work shall make a significant contribution to the predictive process design of the cutting process by means of Finite Element (FE) simulations for the virtual representation of the reality in the sense of the digital twin. To achieve the objective, extensive empirical examinations were conducted in a first step, which included conventional material scientific and orthogonal cutting tests. This enabled the establishment of a database of the workpiece response with increasing thermo-mechanical loads. During the orthogonal cutting examinations, integral and locally resolved process results were measured, which were used as calibration and validation variables in the modeling of the workpiece material behavior. By extending an established friction test bench with a workpiece pre-heating system, the friction conditions between tool and workpiece could be investigated under conditions equivalent to the cutting process. Based on the experimental results, a friction model was derived, in which the observed effects of thermal softening and the localized adhesion-induced increase in the apparent friction coefficient were superposed. A phenomenological material model was developed to describe the workpiece material behavior in the cutting process. The formulation of the material mode was developed based on empirical examinations as well as results from the state of the art. The material model was implemented in an FE-chip formation simulation using a subroutine. A hybrid optimization algorithm was developed to inversely determine the material model parameters. By means of the optimization algorithm, the material model parameters could be systematically determined inversely, taking the experimentally determined process observables into account. An automated procedure linked to a user interface lowered the entry hurdle for industrial companies and unexperienced users of FE-simulations and reduced the computational effort for the inverse parameter determination to about 10 days of computational execution time. The quality of the developed models and the determined model parameters were further verified by a final deduction step using the industrial example of face turning.
