Reverse engineering of a flower-stem guillotine

Full CAD reconstruction of an existing guillotine for cutting flower stems. A 12-part assembly rebuilt in Shapr3D. Delivered 13 STEP files, 6 DXF laser-cut profiles, and 6 dimensioned A3 drawings with a bill of materials. Plates 4 to 5 mm, M6 and M8 threads, largest part 610 mm.

Main plate 610 x 310 mm, 4 mm: M6 threads, ø5 to ø10 holes, section view and isometric.IE-009 · FIG.01 · Main plate 610 x 310 mm, 4 mm: M6 threads, ø5 to ø10 holes, section view and isometric.

Problem

The client had a working physical machine with no technical documentation at all. To reproduce it, order laser cutting, and service it, they needed a complete production package: 3D models, cut profiles, dimensioned drawings, and a bill of materials. The challenge was faithfully reconstructing the geometry, hole fits, threads, and plate thicknesses from measurements of the existing machine alone.

Outcome

A complete production package delivered: 13 STEP files, 6 DXF laser-cut profiles, 6 dimensioned A3 drawings, and a bill of materials. The geometry reconstructed from the original is ready for reproduction, laser-cut ordering, and future modifications without access to the physical machine.

  1. 01Measuring and disassembling the existing guillotine. Cataloguing the 12 parts, measuring holes, M6 and M8 threads, and plate thicknesses (4 to 5 mm, with a 1 mm bent-sheet housing).
  2. 02Reconstructing each part in Shapr3D and assembling them into a single model, preserving hole fits and the moving-blade mechanism.
  3. 03Flattening the flat parts into 6 DXF profiles ready for laser cutting, and exporting 13 STEP files (12 parts plus the full assembly).
  4. 04Producing 6 dimensioned A3 drawings with section views, threads, and counterbores (for example ø12.2 over ø6), plus a bill of materials (BOM).
