µForm - Additive manufacturing of form electrodes

Additively manufactured form electrodes — © Fraunhofer IPK

Motivation:

EDM of materials which are difficult to machine
Additive manufacturing with cemented carbide

Focus areas:

Material-analysis and optimization of the manufacturing parameters selective laser melting
Additive manufacturing of individualized tool-electrodes with integrated irrigation channels and high aspect ratios
Designing of the SLM and EDM process

Objectives:

Process chain for manufacturing of electrodes
Improvement of process conditions at EDM: higher ablation rate, less wear

Projects:

FEMRO, µForm
