Carved fan cassette

The corner fan carved into the panel: the pleats go in instead of out, the zigzag edge dips behind the face, ridges become valleys. Adjustable pleat count and depth.

Fabrication data

Carved fan cassette — at 600 × 400 mm in 4 mm ACM, this family unfolds into a 728.3 × 519.5 mm flat pattern with 21 folds, including 1,664 mm of groove machined from the visible face, with the sheet flipped for that pass. A 1,500 × 3,200 mm sheet holds 12 of them, for 15.2 % 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. The pleats dip BEHIND the face of the panel: their bottom must stay at least 5 mm in front of the tab plane, otherwise the relief hits the framing and the cassette no longer sits flat on its rails. A carved fan therefore needs a deeper return than a raised one.
  7. A V-groove is cut on the CONCAVE side of the fold. Carved, the fan reverses its folds: former ridges become valleys and go on the RAINURE_AVANT_* layer, machined face up with the sheet flipped; the rest is grooved from the back.
