*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.

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°).

*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.
