Inspect a guided blanking press, punch, sheet, die opening and falling blank. Compare the estimated shearing requirement with press capacity and see a capacity-limited stroke stall before separation.
• A 3D process cutaway of a blanking press, shear force and a capacity-limited stroke, with labeled components you can select. • Controls: Sheet thickness (1-3 mm), Material shear strength (150-350 N/mm²), Press force capacity (20-150 kN). • Live readouts: Estimated blanking force; Applied force; Punch stroke; Sheet penetration; Blank separated; Capacity minus requirement. • Three guided experiments (Adequate capacity, Overloaded press, Thicker stock), a built-in model verification check, a timestamped event log, a trial report and a short knowledge check.
Blank perimeter = 2(40+20) = 120 mm Peak shear force = perimeter × thickness × shear strength /1000 kN F(penetration) = peak × penetration/thickness until separation Capacity-limited penetration ≤ thickness × capacity/peak.
Quasi-static idealized blanking, one operation per reset. Real fracture generally completes before full-thickness penetration, and clearance, wear, stripping force, impact and burrs are not solved. This is one specific stamping operation, not a sheet-forming finite-element model. Dimensions, motion and process time are enlarged where stated for explanation. These are educational models, not machine programs or qualified production procedures.
Yes. The simple perimeter × thickness × shear-strength formula is linear in thickness.
No. Actual blanking fracture depends on clearance and material behavior.
