Turn the X-Y-Z bend coordinates from a drawing into the bender setup sequence — the feed (Y), rotation (B) and bend angle (C) for each bend, plus arc and tangent. Same maths as the bend-procedure sheet, machine-side.
Read the machine, not the letters. YBC letter assignments differ by bender brand — match each value by what it is: Y = straight to feed, B = roll between bend planes, C = bend angle (DOB, the degrees the machine bends through — not the included angle). Rotation sign (CW/CCW) is convention-dependent: verify the first result against a part you already know and use the flip toggle if it reads mirrored. Feed depends on the bend radius (CLR), which the coordinates don't contain.

Enter the apex / intersection points (PT 0 = start, then each bend vertex, last = end) — the same points as the drawing's bend table. Bends happen at the interior points.

Feed (Y) = straight to advance before each bend (tangent-corrected, uses CLR). Rotate (B) = roll between planes; the first bend has none (datum). Bend (C / DOB) = degrees the machine bends through = 180° − included angle. Springback is not applied — overbend per your own test bends.
