2. Modification of geometry and change of process

2.1 Methodology

When designing a part, or in this case redesigning one, the first questions that come to mind are: where to start? And how to proceed?

To address this, a methodology is proposed.

Key points to remember

  1. 1. Define interfaces and functional areas.

  2. 2. Define a design volume.

  3. 3. Define a design objective (minimum mass, maximum stiffness, cost, etc.) and design constraints (safety factor, etc.).

  4. 4. Perform topological optimization.

  5. 5. Define a manufacturing direction.

  6. 6. Define the...
