Machining 3D surfaces

In the die & mould sector, the manufacture of increasingly complex forms is part of everyday life. Continuous further developments in machine tools and CAM software raise performance and productivity to an ever higher level. The tools used must therefore always be state-of-the-art. To achieve optimum results, each design starts with a process analysis.
On a rendered example component, an operation is highlighted.

Desbastado

El desbastado abarca prácticamente toda la tarea de mecanizado. Optar por estrategias de fresado especiales como el mecanizado de gran avance o el fresado trocoidal puede reducir el tiempo de mecanizado y, por tanto, aumentar la rentabilidad. Aparte de las herramientas con insertos de corte y fresas de metal duro, se emplearán fresas de alto rendimiento con formas de desbastado especiales.

Residual material roughing

After roughing, in a second machining step, users machine the residual material, especially in corners and cavities, removing material as constantly as possible. Usually tools with corner radius or high-feed milling cutters are used. In some cases a ball cutter can be used to remove the residual material in corners.

Pre-finishing

If there are high demands on dimensional accuracy and surface finish, semi-finishing is recommended before finishing. With pre-finishing, machining approaches the final mould profile. The aim is to obtain a residual material that is as constant as possible in order to enable fast finishing with high demands on the surface quality. The stock removal after roughing is approx. 0.5-1 mm for hardened materials and 0.03-0.5 mm for soft materials. After pre-finishing, the constant stock removal is 0.05-0.1 mm for hardened materials or 0.1-0.3 mm for soft materials.
