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.

  • *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 When a is not secured by the slit’s horizontal width, or when there is an acute angle bend, we can still provide an estimate, but instead of the limit value c, the aforementioned “Minimum distance between the hole and the bend” will be the limit value for the hole position.
  • *2 If the slit’s height is smaller than b or the outside R (fillet size) of the bend, automatic quotation is not possible.
  • *3 The limit value c is uniformly 3.0 mm only when the nearby hole in the right figure is a burring tap.

Minimum Angle for Acute Angle Bending

Machining Limits, Size RangeExample
  • The angle (θ) for acute angle bending must be 45° or more.
  • (However, when the plate thickness is 9 mm, the acute angle (θ) must be 88° or more.)
