1. Theoretical and experimental studies of a single tooth milling process
Sammanfattning : The industrial development of metal cutting processes in gear manufacturing aims at continuously increasing productivity, including increased tool reliability. Basically, the parameters that have an influence on the cutting processes should be known and possible to control.Gear manufacturing is highly important for the automotive industry. LÄS MER
2. Mechanical Load Identification for Spontaneous Tool Failure Monitoring
Sammanfattning : The problem of spontaneous cutting tool failure, such as tool chipping and breakage, is becoming more and more important in the manufacturing technology. The sponataneous tool failure is usually associated with the stresses subjected on the tool during a metal cutting process. LÄS MER
3. Investigation of Forces and Contact Area for Modelling Turning Processes
Sammanfattning : This thesis is focused on an investigation of forces andcontact area for modelling turning processes. The primary taskin short term research has been to take a first steptowards animproved model of the cutting process. LÄS MER
4. Individual-tree-selection in uneven-sized Norway spruce stands in southern Sweden : Developments of tools for simulation and optimization
Sammanfattning : Individual-tree-selection (ITS) is a continuous cover forestry method that aims to utilize the uneven-sized stand structure through optimized individual tree selections. ITS is an interesting management alternative to rotation forestry in terms of production of multiple benefits and forest owner profitability. LÄS MER
5. Optimisation of Machining Operations by means of Finite Element Method and Tailored Experiments
Sammanfattning : The experimental approach has long been the main method to investigate the responses associated with metal cutting process such as cutting forces and temperatures and also to optimise the machining operations to accomplish higher productivity. In recent years, with advances in computing power of computers along with development of robust numerical methods such as Finite Element Method (FEM), it has been possible to simulate different machining process under operational conditions.
