T20 – Collaborative Research Centre 871: Regeneration of Complex Capital Goods

T20 - Material-related process design for ball head milling of complex capital goods

The 5-axis milling of complex capital goods places high demands on process planning, as different materials and geometries require specific machining strategies. High-performance materials that are difficult to machine, such as Inconel or tool steels, in particular, generate high thermomechanical stresses that have a significant impact on tool life and machining quality. The T20 transfer project addresses these challenges and investigates how material- and process-specific parameters can be systematically integrated into the design.

Motivation

Previous process design has often been based on empirical parameters, while model-based methods for predicting machining behavior and tool stress have only been used to a limited extent. This offers considerable potential for increasing machining efficiency and reducing tool costs by aligning process parameters more closely with material and component characteristics. The aim of the project is to develop a material-related methodology for process design that uses both milling tests and highly dynamic analysis methods to define robust strategies for 5-axis milling of complex components.
