加工したいねじの呼びとピッチが表示されない＜threadpro＞ | オーエスジー

The size and pitch of the thread I want to machine are not displayed.

If the thread type is M (meter) and you cannot select the size and pitch of the thread you want to machine, select "Custom" in the thread type field.

In this case, the size and pitch of the screw are direct input (mm).
Example: M10×1.5
Thread size =10(mm)
Pitch = 1.5 (mm)

Unified threads can also be programmed by converting (inch) to (mm).

The size of the screw (outer diameter of the screw) should be converted to 1 (inch) = 25.4 (mm).

The pitch is calculated by 25.4 (mm) ÷ the number of mountains, rounded to the fourth decimal place, and entered to the third decimal place.
Example: 3/4-32UN
Thread size =25.4(mm) × 0.75(3/4) = 19.050(mm)
Pitch = 25.4 (mm) ÷ 32 = 0.7938 ≈ 0.794 (mm)
