面取り幅については変更前後で大差ありませんが、面取り角度が変更後のほう

面取り幅については変更前後で大差ありませんが、面取り角度が
変更後のほうが小さくなっています。
これは、角度が小さいほうが面押し時の逃げが少なく、プレス加工時の圧力を少なく出来るため、
角度を小さ目に狙っているためです。

結果 (英語) 1:

It is not much different from before and after the change for the chamfer width, but more of
after the change is smaller chamfer angle.
This is because for better angle is small less surface relief of press time, it is possible to reduce the pressure of the press during processing, it is aiming to a smaller angle
.

結果 (英語) 2:

Not much different before and after the change on the chamfer width the chamfer angle
smaller than those after the change.
For this angle is smaller than the flank surface holding time less, be less pressure during press
is aimed to small angles.

結果 (英語) 3:

I don't have it of a wide margin about the bevel face width in change front and back, but the
change back shrinks a chamfering angle.
This is because I aim at a
angle into small pieces in order that there are few escapes at the time of the aspect push, and the one where an angle is small can reduce pressure at the time of the press working.
