Improving part flatness
There are some measures to be taken, when parts have to be produced through the dies to improve the part flatness (Blanking out parts).
| flat | ← | punch | → | whisper shear 1/2 of s |
| normal | ← | stripper | → | active |
| cylindric cut | ← | die | → | big free angle |
| normal | ← | clearance | → | significantly decreased (depends on the material) |
