Specifiable angular tolerance
Angular tolerances
- You can specify angular tolerances for the angles between surfaces.
- You can select the blank side or pocket side.
Specifiable tolerance range
| Tolerance range (Θ) | |
|---|---|
| Automatic Quotation | 0.16°≤Θ≤10° |
| Manual Quotation | 0.02°≤Θ＜0.16° |
When selecting heat treatment and nitriding, the following tolerance ranges can be specified
| Tolerance range (Θ) | |
|---|---|
| Automatic Quotation | 2°≤Θ≤10° |
| Manual Quotation | 0.02°≤Θ＜2° |
*General tolerances will also be estimated by the ｍanual Quotation.
Unit of angular dimension
- The unit of angular dimension is in decimal notation. (e.g. 30.5°±0.2°)
- *Notation in minutes and seconds (sexagesimal) is not supported.
Processing examples
Surfaces for which angular tolerance cannot be specified
You cannot specify angular tolerances for the following surfaces.
hole opening
Chamfer
R-side
Surfaces that are not parallel to the six sides
*The dimensions displayed on the selected surfaces must be parallel to one of the XYZ surfaces.
surfaces that are too small
*The selected area must be at least 9 mm².
Surfaces with an angle of 180°
Precautions
- One-sided tolerances are quoted by the ｍanual quotation.
- In the event of overlapping dimensions, we will prioritise the following in order.
