Milling of tungsten carbide-based mmc-materials – optimization of micro-milling parameters for industrial application Parameteroptimierung des mikrofräsprozesses für den industriellen einsatz fräsen vonwolframkarbid-basierten mmc-werkstoffen

The production of plastic parts by injection molding is wide-spread due to its high cost-effectiveness. Micro-milling of the needed molds from non-ferrous metals instead of steel can further increase economic efficiency. In order to meet the local loads during injection molding, these molds can be reinforced by inserting tungsten carbide particles into their surface where needed. The subject of this investigation is the micro-milling process of the resulting metal-matrix-composite materials. Binderless polycrystalline diamond was qualified as an inno-vative cutting material and the potential for industry was demonstrated.
