Turret Punch Resource

Die Clearance &
Punching Force.

Estimate total and per-side die clearance, recommended die dimensions, punching force and press-capacity utilization.

Application Inputs

Material and Tool

Material Material thickness in. Shear strength ksiksi means 1,000 pounds per square inch. Shear strength is the material’s resistance to being cut. Clearance objective Tool shape Punch diameter in. Number of holes per hit Press capacity short tonsOptional. Enter 0 to suppress utilization results. Planning factorAllows for normal variation; dull tooling may require more force.

Confirm the Tooling, Station and Machine Limits.

Total vs. Per Side

Total clearance is the full difference between punch and die dimensions. Clearance per side is one-half of the total.

Inspect the Hole and Slug

Burr, rollover, burnish, fracture angle, slug condition and uneven wear help confirm whether clearance and alignment are appropriate.

Sharp and Aligned Tooling

The force estimate assumes sharp tooling, suitable clearance, correct turret alignment and full cutting engagement.
