Aplicação de fresagem helicoidal

Um foco principal nas operações de fresagem é a redução do tempo de usinagem. Com geometrias de ferramentas específicas para usinagem de bolsos fechados e redondos, muitas vezes é possível eliminar o processo de pré-perfuração. Na fresagem helicoidal, os caminhos de ferramentas são programados com entradas helicoidais adequadas para dimensões de bolso.
On a rendered example component, an operation is highlighted.
Visão geral das ferramentas para as seguintes etapas de usinagem:
  1. Usinagem de desbaste de componentes
  2. Material residual desbaste
  3. Semi-acabamento
  4. Acabamento

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.

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.
