Mitre matching: why it matters in linear 1D cutting

What angle-aware packing means in Corte 1D, which loss it tries to share and which limits a metal workshop must validate.

Short definition

Mitre matching is an optimisation strategy that tries to place pieces with compatible angles and orientations together so part of the geometric cutting loss can be shared. In Corte 1D it appears as the packing engine’s angle-aware mode.

It does not turn two mitres into one operation by definition. The engine must first represent a compatible arrangement, and the workshop must then confirm that it makes sense for the actual profile and machine.

Why it matters for profiles and structures

A square cut and a mitre do not consume material in the same way. When several pieces have compatible mitres, always separating them as independent cuts may overestimate the loss and produce a worse pattern.

Angle-aware mode compares supported placements and orientations and favours sharing an angle when the represented geometry allows it. The result still displays pieces, dimensions, kerf and remnants for office and workshop review.

Supported angles and orientations

The current input accepts 45° and 90° at each end, with incoming, outgoing or not-applicable orientation. This must not be interpreted as support for arbitrary angles or every profile intersection.

If an imported file contains an unrecognised angle or orientation, the row needs review. Normalising a value so processing can continue does not prove that the piece is manufacturable.

Physical validation before production

Mathematical compatibility does not replace checking the real profile. Review the reference face, measurement convention, tool, cutting direction, clamping and the saw’s working clearance.

Before a series, check a first piece and confirm that the calculated remainder matches the process. Corte 1D helps prepare and communicate the decision; it does not replace CAD, the manufacturing drawing or the operator’s judgement.

  • Confirm profile, material and reference face.
  • Review 45° or 90° and orientation at both ends.
  • Verify kerf, clamping and feed direction.
  • Measure the first piece before repeating the pattern.
