The workpiece geometry during deep drawing is determined by the geometric information stored in the tool. The most important tool parameters are:
- Clearance uz
- Die radius rM
- 4Ming Curve
- Bottom radius rB
- Punch radius rSt
- Friction values
- Entry angle
- Elastic tool and press behavior
- blankholder pressure pN
