In mould manufacturing the most representative component is the cavity, which can represent up to 75% of the total cost of the tooling and can reach 40% of manufacture time. In regions with small sizes and area with difficulty access to the cutting tool with "common"size (>2mm).These areas have been machined by EDM which has a negative impact over the cost and time of manufacture of the mould cavity. Therefore, surveys are developed in order to reduce the use of EDM in industry; among the alternatives, the micromilling process, using high-frequency spindle together with cutting tools smaller...
