Optimization of surface properties for a volumetric optimized component

Purpose and goal

The project has investigated how the residual stresses are affected after different processing steps in the machining of a volume optimized component. The main goal of the project has been to investigate if and how much the previous processing steps affects the final surface residual stresses.

Expected results and effects

The results from this project has clearly showed the signature from various tools and tool wear levels on the processing. In addition, the results have shown how the preceding machining steps affect the respective steps in a typical machining operation where different processing sequences are typically used with different tools.

Planned approach and implementation

Implementation has been done performing machining test in different machining steps using different test pieces and cutting tools. The machined surface was then in detail investigated in terms of topology and residual stress for each individual machining step.
