In recent years, the number of products containing complex shapes that are produced by tooling known as dies and moulds have grown noticeably. The quality, costs and lead-time of these products are strongly influenced by the manufacturing process of these toolings. The more complex the product shape, the more intensive has the work to be expanded. The development of CAD/CAM systems and High Speed Cutting Technology (HSC) have greatly helped to improve the manufacturing of such kinds of dies and mould. However, technological limitations in the CAD/CAM/CNC to produce free form geometries have...

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...
