Applicazione dell’interpolazione elicoidale

Uno degli obiettivi principali delle lavorazioni di fresatura è costituito dalla riduzione del tempo di lavorazione. Spesso è possibile eliminare il processo di preforatura grazie alle geometrie specifiche dell’utensile volte alla lavorazione di tasche chiuse e rotonde. Nell’interpolazione elicoidale, i tracciati di fresatura vengono impostati con ingressi elicoidali idonei alle dimensioni delle tasche.

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.
  • OptiMill®-3D-HF

    Solid carbide high-feed milling cutter
    • Perfect for high-feed machining with a high material removal rate and high process reliability
    • Innovative face geometry
    • Extremely quiet running

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.

Finishing

The finishing process removes the remaining material in order to achieve the final shape. After pre-finishing, stock removal is 0.05-0.1 mm for hardened materials or 0.1-0.3 mm for soft materials. Ball and/or corner radius milling cutters are the tools of choice, regardless of the final contours of the workpiece.
