Productivity increase in hard machining of steels based on Process Signatures (T03*)

• Subject Area: Metal-Cutting and Abrasive Manufacturing Engineering
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 223500200

The overall objective of the transfer project is to develop technological solutions for increasing the productivity in industrially used geometrically defined hard machining of steels with special consideration of the workpiece surface layer and tool wear. For this purpose, based on experimental and simulative analyses, a Process Signature and the further correlations of the causal sequence for external longitudinal turning of induction-hardened workpieces made of 42CrMo4 are to be developed. By considering the tool wear, a further scientific development of the Process Signature concept with the aim of a higher practical relevance is sought.
