K-factor in sheet metal bending: values and how to measure it
K-factor moves from about 0.33 to 0.50 as the bend radius grows. Values by R/t, a coupon procedure that measures your own K, and what a 0.02 error costs on the flat.

K-factor moves from about 0.33 to 0.50 as the bend radius grows. Values by R/t, a coupon procedure that measures your own K, and what a 0.02 error costs on the flat.

Minimum bend radius by material: inside-radius multiples for CRCA, stainless, aluminium, copper and brass, with the strain and springback numbers behind them.

Minimum flange length by thickness and die opening, why a short flange drops into the die, and how to design below the limit without losing the bend angle.

A hole inside the V-die zone bends and ovalises. The formula, a table by thickness, and four fixes when the hole cannot move away from the bend.

Why 304 and 316 mark on the press brake, what galling actually is, and the radius, die opening and tonnage numbers that keep the face clean.

Bend radii, springback and die rules for 5052, 5083 and 6061 aluminium on a press brake, with the numbers that stop edge cracking and over-bending.

How box bending fixes 19-inch enclosure width, corner relief and bend order, with tolerance limits, coating spec and a first-article inspection plan.

Bending long panels without distortion: crown compensation, bend sequence and handling rules for panels up to 4,450 mm, plus the numbers to inspect.

STEP files for sheet metal bend review: what the model carries, what it does not, and the checks that catch an unbendable part before the tool is set.
The guides follow the same questions as the free tools. Size a press, check a bend, estimate a cut part or build the RFQ pack.
