Logic for Judging Thin Walls

The threshold value for thin-wall thickness, at which tears or shape distortion may occur during production, is as follows.

Residual Thickness After Product Machining

[mm]
Iron/Steel, SUS, Aluminum
Machining Limitation1.0
  • *If an external or internal thread is specified, the possibility of machining will be determined by the factory based on the shape.
  • *This is the threshold value at which tears or distortion in the shape may occur during production.

Volumes of the Model with Deformation Concerns

  • If the ratio of model volume to material volume falls below the threshold value, the shape may deform.
  • The material volume is calculated by multiplying the radius of outer-most diameter × radius × pi × full length.

Tip

  • Modify the 3D model so that the model volume is greater than or equal to the threshold value.
