Integrated Approach for a Knowledge-Based Process Layout for Simultaneous 5-Axis Milling of Advanced Materials

Abstract EN

Advanced materials, like nickel-based alloys, gain importance in turbomachinery manufacturing, where creating complex surfaces constitute a major challenge.

However, milling strategies that provide high material removal rates at acceptable tooling costs demand optimized tool geometry and process parameter selection.

In this paper, a description of circular milling is given, focusing on resulting engagement conditions.

Regarding this, a test bench was designed to investigate the chip formation process in an analogy milling process.

Furthermore, the methodology for the approach in the analogy process was developed.

Results of a first test run in Inconel 718 verify the presented approach.
