Chevron cassette

A V-shaped broken ridge: two ridge ends and an offset central point, at adjustable height. Free ridge length and chevron offset; laid in turned rows, the pattern becomes a continuous zigzag.

Fabrication data

Chevron cassette — at 600 × 400 mm in 4 mm ACM, this family unfolds into a 715.4 × 521 mm flat pattern with 15 folds, including 774 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 13.8 % 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 offset is bounded by the ridge length (k < r·H / (2 − r), r = length / width): beyond, the ends would pass behind the point and the facets would flip.
  7. The ridge ends stay above the point–corners plane: a drop too large is brought back to its maximum (the ends would be saddles).
  8. The chevron offset is at least 10 mm in absolute value, otherwise the point merges with the ridge.
