Small mould tool manufacture from tool steel blank directly from CAD design by laser micro erosion using Q-switched YAG laser (~100 W). the laser is delivered via galvanometer scanners and removes material layer-by-layer to generate up the 3D cavity designed. Depth dimensional feedback is shown periodically using a probe. Removal is highest quality at lowest volumetric removal rates at lower pulse energies - here, the material removal mechanism is mainly vaporisation. Removal is lower quality at higher volumetric removal rates at higher pulse energies - here, the material removal mechanism is mainly melt removal.
