BENDIQ: Press Brake Calculator

THE RIGHT FLAT PATTERN, FIRST TIME. Bend deduction learned from your machine; the result checked in 2D, 3D and 4D before cutting. BENDIQ is a sheet metal bending calculator for the press brake operator: flat pattern, bend calculation and cut length. It combines bend deduction, bend allowance, K factor and setback with checks made before production: CALCULATE → CHECK → SEE → BEND → OUTPUT Enter material, thickness, V die and angle; the flat pattern (cut length) and leg dimensions are on screen in seconds. Check in 2D, 3D and 4D BEFORE you bend — then send the same unfold to the laser as DXF. ✔ 15-day free trial — sign in with Google, no card needed ✔ Monthly or yearly subscription — cancel anytime ✔ 25 languages 1) CALCULATE — FLAT PATTERN AND BEND DEDUCTION Every result comes from standard sheet metal formulas: bend deduction, bend allowance, K factor and setback. Start from ready profiles (L, C, U, Z, Hat, Lipped C) or draw your own section; plate, angle and channel unfold from the same core. 2) CHECK — CALIBRATION FOR YOUR PRESS BRAKE No two machines or dies give the same result. Enter the value you measured on a test bend once; BENDIQ learns your machine's real bend deduction for that material–thickness–die set. Not a generic table — your own shop data, kept on your device. An impossible bend warns you before the part reaches the cutter. 3) SEE — 2D DRAWING, 3D MODEL, 4D BEND ANIMATION • 2D: dimensioned technical drawing — sizes, angles, radius, section • 3D: solid model with the real bend radius • 4D ANIMATION + REAL COLLISION SIMULATOR: punch descends, angle closes, part is turned, the next bend follows. The part is checked against catalogue tools, machine body and back gauge; on a hit you see the damage — which bend deviates and by how many degrees — before the sheet is cut. 4) OUTPUT — DXF, 1:1 TEMPLATE, PDF • DXF (R12) FLAT PATTERN: send the cutting file to your laser or plasma. It is built from the SAME unfold as the cut length on screen. Tapped holes are written at pilot diameter (M10 → Ø8.5). • 1:1 A4 CUTTING TEMPLATE: no laser? Print the unfold at true scale, lay it on the sheet and mark. Every page carries a 100 mm check ruler. • 15 READY PLATE TEMPLATES: corner, centre, diagonal, edge-pair and slotted hole layouts. Save your own parts as templates too. • A4 TECHNICAL REPORT / QUOTE PDF: share it with your company name and logo. • HOLE LAYOUT: every drilled face on its own A4 sheet, full size, with X0/Y0 datum and dimensions. Round, slotted and rectangular holes; M3–M12 tapped and countersunk; linear or grid arrays.
