ACM fabrication guide

Six answers to the questions a cutting workshop or a design office asks in front of a 3D cassette in aluminium composite. Each guide starts from a question, answers it in three sentences, then develops with the engine’s real values: nothing is claimed that the generator does not do.

  1. 015 min readHow to unfold a 3D ACM cassette (pyramid, slope) without wasting a sheetWhy a pyramid in aluminium composite needs a V-slit (angle sum < 360°), how the generator picks folds and seams, and what the workshop reads in the DXF.Diamond cassette · Single-slope cassette · Ridge cassette · Star cassette
  2. 025 min readV-groove for 4 mm ACM: cutter angle, depth, residual skin and layersWidth and depth of a V-groove in 4 mm aluminium composite (Alucobond, Dibond, Reynobond), 0.4 mm residual skin, nominal vs apex angle, RAINURE_90 and RAINURE_135 layers, double groove.Flat cassette · V cassette · Faceted wave · Single-slope cassette
  3. 035 min readBend deduction in aluminium composite: why “deduction = thickness” is only a defaultWhat the bend deduction removes from the developed length of an ACM cassette (Alucobond, Dibond), how the generator distributes it, and the U test-piece method: a single caliper measurement per cutter angle, r = r0 + (measured − L).Flat cassette · Diamond cassette · V cassette · Faceted wave
  4. 046 min readReturns, fixing tabs and corner reliefs: the rules the generator appliesTab set-back = max(return, tab) + 2 mm, minimum return = groove width + half deduction, tool-radius relief at corners, square, oblique and split corners: what an ACM cassette DXF contains and why.Flat cassette · Star cassette · Fan cassette · V cassette
  5. 055 min readReading an ACM cassette DXF: layers, R12 vs R2000, back view, units, marksThe generator’s DXF contract: eleven named layers (CONTOUR, RAINURE_90, RAINURE_135, PERCAGE, REPERE…), R12 by default, millimetres, mirrored back-side frame, strict ASCII text. What the CNC operator checks before machining.Flat cassette · Perforated cassette · Faceted wave · Diamond cassette
  6. 064 min readNesting on 1220 × 2440 and 1500 × 3200 sheets: grain direction, margin, waste and cut sheetHow the generator lays ACM cassette patterns on the sheet: 10 mm edge margin, 8 mm gap, rotations according to grain direction, waste calculation, and what the printed cut sheet contains.Flat cassette · Truncated pyramid cassette · Hexagonal plateau cassette · Diagonal band cassette
