Fabrication data

Fan cassette — at 600 × 400 mm in 4 mm ACM, this family unfolds into a 740.5 × 532.1 mm flat pattern with 21 folds, including 1,221 mm of groove machined from the visible face, with the sheet flipped for that pass. A 1,500 × 3,200 mm sheet holds 8 of them, for 41.4 % 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.
