Solution approach and results
In order to be able to determine which tool coatings, nitriding, tool geometries and cutting-process parameters might be suitable, these were investigated, tested and compared with one another in various versions. Measurements taken on variously coated surfaces and the determination of tribological behavior against FRP, wear behavior, and component or release quality in cutting tests allowed property/parameter correlations and recommendations to be derived.
With active parts coated for specific applications, the project was able to achieve performance improvements such as wear reduction of around 70 percent. Furthermore, the tests showed that drawing cuts such as bevel cuts with a small wedge angle as well as a small kerf achieve good cutting results.
Suitable tool coatings, geometries and stamping-process parameters are essential for the economical trimming of FRP components. Through the project results and application recommendations, important preliminary work has been carried out which enables the manufacture of FRP components in an automated, reproducible and efficient manner. As a result, this high-performance material has been made more attractive for sectors such as the automotive industry. The expertise acquired supports users, toolmakers, coaters and FRP manufacturers in positioning themselves on the market and opening up further fields of application.
