| Project title | Development of a model for the automated determination of the ideal lubricant layer thickness for hot forging (Minimalmengenschmierung) |
| Project duration | 01.09.2023 – 31.12.2025 |
In subtractive manufacturing, the use of minimum quantity lubrication is widely known. Despite its cost and environmental protection potential it is not yet used in the field of hot forging. This is especially due to the lack of fundamental knowledge, which has to be obtained within this project. For this purpose, experimental investigations and accompanying simulations will be carried out and combined into one overall model.
This enables a statement about the ideal lubricant thickness, which considers particularly the specific problem of locally different tool loads and the associated effects, such as lubricating film breakage and tool wear.
Publications about the project
Determining suitable lubrication settings is crucial for designing an effective hot forging process. Currently, this determination is predominantly carried out through trial and error at the beginning of production, with subsequent adjustments based on the operator’s expertise. To reduce manual labor, costs, and especially resource consumption, it is advantageous to enable the selection of appropriate lubrication settings in advance. This supports the industry in achieving its carbon–neutral objectives while enhancing process stability. This paper presents simplified experimental methods to evaluate the tribological properties of hot forging processes; the ring compression test was chosen to determine the influence of the lubrication layer thickness on the tribological system. This study was structured in two stages: first, a design space exploration of spraying parameters; second, an evaluation of the friction factor for various lubrication layer thicknesses.
