Fabrication data

Perforated cassette — at 600 × 400 mm in 4 mm ACM, this family unfolds into a 704 × 504 mm flat pattern with 8 folds, all grooved from the back: no pass on the coated face. A 1,500 × 3,200 mm sheet holds 12 of them, for 15.7 % waste.

Manufacturing constraints

  1. The return must exceed the groove width plus half the bend deduction, or the groove eats into the return.
  2. Facet-to-facet folds are grooved with the smallest cutter of the profile, V left open: the angle is held by the geometry. The angle between two facets must not exceed that cutter’s apex angle.
  3. Vertical returns, all tabs flat in the −D plane (rail mounting). The facet-to-return fold is 90° ± slope: below 90°, the 90° cutter is left open and the return is held by the riveted tab; above 90° (facet descending towards the edge), a wider cutter (60° nominal = 120° apex) or the machine profile’s overfold tolerance is needed.
  4. Every raised vertex requires a V-slit to the edge (a flat sheet has 360°, the relief less). Near the vertex the slit is narrower than the contour tool: it is cut along its axis and the tool bites each facet by up to Ø/2.
  5. Tabs are shortened at every corner and every kink of the edge so they never collide behind the panel: by (return + 2 mm), and more on a sharp corner, where the bisector must be cleared (tab width ÷ tan(angle/2)). An edge too short gets no tab.
  6. Holes at the given pitch: the largest hole is reduced to keep at least the contour tool diameter of material between neighbours; every hole fits inside the facet minus the margin. Holes smaller than the contour tool are drilled (PERCAGE layer).
  7. The edge margin must cover half the bend deduction (the fold axis moves into the facet) plus half the widest groove, or a hole bites into the V-groove.
