Range of Machining Limits

    The limits for machining and the size ranges are defined for each standard part. Make sure that any models you create fall within the standard range.
  • *Values may differ from those listed depending on surface treatment, shape, and processing conditions.

Example

  • *The distance between a tapped hole and the edge or between tapped holes is determined by the minimum distance from the outermost diameter of the tapped hole.
  • *The distance between friction drilled/tapped holes is determined from the minimum distance from the center of the hole.
  • *The distance between a countersunk hole and the edge or between countersunk holes is determined by the minimum distance from the outermost diameter of the counterbored part.

  • *1 The hole may be deformed if it is below the minimum value.

    The dimensions are therefore inaccurate, but will be processed as they are.

  • *2 If the distance is under the minimum value, re-tapping will be necessary and the fit may be affected.

Example

If there are internal angles of less than 90°, machining may not be possible even within the safe value range. If this is the case, meviy Support will contact you.

  • *1 The hole may be deformed if it is below the minimum value.

    The dimensions are therefore inaccurate, but will be processed as they are.

  • *2 If the distance is under the minimum value, re-tapping will be necessary and the fit may be affected.

Example

Slit on the bending line (except for acute angle bending shapes with an internal angle of less than 90°).

  • These comparative examples are a selection of representative materials and hole types. It is also effective with other materials and hole types that are not listed.
  • Comparison of the outer radius of a bend (fillet size) and the height of the opening on the bend line when modeling to the minimum value “b.” · If the height of the opening is modeled to greater than “b,” the h2value will differ.
