Abstract High loaded, case-hardened workpieces are often finished by grinding to meet required form tolerances and generate high-quality surfaces. The thermo-mechanical load during grinding influences the surface integrity and therefore the functional behavior of the workpieces. To increase productivity, grinding processes are often operated at their limit. Therefore, already even minor deviations from the desired process conditions can lead to thermo-mechanical damages, often referred to as gri...

Abstract Die sinking EDM processes are widely employed in advanced aerospace applications where part quality and machining time are main concerns. The aim of this research work is to develop an advanced EDM process monitoring procedure in the perspective of Zero Defect Manufacturing based on the identification of correlations between die sinking EDM process parameters and improper process conditions that could increase machining time and cause unacceptable part quality. To this purpose, the Real...

Abstract Electrically conductive ceramics are increasingly used in tooling and chemical industry, because of their high thermal and chemical resistance. The high hardness of the material is a major challenge for conventional manufacturing processes. Wire electrical discharge machining (WEDM) offers a good alternative, because the machining process is independent of the hardness. Nevertheless, the thermal material removal principle of WEDM leads to a microstructure change in the near-surface laye...
Abstract The presented investigation focuses on the correlation between concrete physical loads and resulting modifications. The physical and in a wider sense chemical loads are called internal material loads. The correlation between the generated internal material loads and the modifications is called Process Signature. This contribution presents some Process Signature components for thermal dominated processes with phase transformation and accompanying hardening. The selection of the Process S...

Abstract Due to increasing availability of feedback data from the shop floor and prevalence of feature technology for CAD data, relevant information for process planning is available in data of completed production orders. Data mining can be used to extract the relevant information, however the identification of suitable methods for the specific domain of macro level process planning is challenging. In this paper, we analyze data types and distributions of process planning problems as well as th...

Abstract Ball end micro milling is a suitable process for the manufacturing of freeform surfaces and therefore appropriate for the manufacturing of material measures according to ISO 25178-70. In previous studies of the authors, ball end micro milling of areal material measures with specified microstructures was experimentally investigated and the influence of the cutting parameters, as well as the influence of the control dataset parameters and the tilt angle were systematically analyzed. The i...

Abstract Functional surfaces have been investigated widely due to different applications in industries. In this paper, the surface functionality was the contrast generated by surfaces orthogonally textured with micro ridges. The principle to generate contrast was the anisotropic reflection led by the bevel surfaces of micro ridges. The surface quality of the micro bevels determined the reflection of the features. In the authors’ previous work, such a functionality was successfully achieved on fl...

Abstract The biomachining properties of copper and powder sintered metal have been investigated using a white-light interferometer, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). A groove was machined on the copper surface and a porous structure was produced on the powder sintered metal in the biomachining. The groove depth of the copper was directly dependent on time but the porous structure depth of the sintered metal was increased with volatility. The element of...
