Short definition
Linear 1D cutting optimisation distributes pieces of different lengths across available bars, profiles, tubes or other linear stock. The calculation accounts for quantities, kerf, real lengths, constraints and remnants to propose patterns the workshop can review.
It is called 1D because the main variable is one dimension: length. It does not place shapes on sheet material or solve three-dimensional intersections. It is also known as 1D nesting, but it is not 2D nesting.
Cut list, nesting and order are different stages
The cut list defines the required pieces. At minimum it needs a reference, length and quantity; it may add material, profile, angles, orientations and notes. Nesting compares how those pieces can be grouped within available stock.
The cutting order fixes the version sent to production: which bar to use, which pattern to run, which pieces to mark and which remainder to expect. Separating the stages prevents a changed spreadsheet from being mistaken for the workshop’s current decision.
Data that changes the result
The nominal bar length is not enough. The plan needs the tool’s kerf, quantities, real remnants and, where relevant, the angles and orientation of each end. A valid Excel row does not prove that the physical material is correct.
Corte 1D supports imports from CSV and XLSX. Reference, length and quantity are essential; mappings may include material, profile, angles and orientations. The office should review columns and warnings before calculating.
- Reference, length and quantity for every piece.
- Real length of full bars and remnants.
- Kerf, angles and compatible orientations.
- The threshold separating a useful remnant from waste.
A remnant and waste are not the same
A remnant is an identifiable leftover the workshop keeps because it has a realistic chance of being reused. Waste is material below the workshop’s practical threshold or material that cannot safely re-enter the process.
Yield percentage helps compare plans but does not guarantee savings. Two patterns can have similar figures and leave stock with very different operational value. The decision depends on inventory, future pieces and real constraints.
What Corte 1D does and does not solve
Corte 1D organises the path from a linear cut list to calculation and a shared office-to-workshop order. Its angle-aware mode tries to share part of the loss between compatible mitres, but the workshop must validate profile, tool, direction, clamping and the first piece.
It does not replace CAD or ERP, does not perform 2D nesting and does not support every geometry or arbitrary angle. The operator view follows an offline-first approach for unstable coverage, although synchronisation and shared operations require connectivity.
Current status
Corte 1D is in private production alpha with one alpha user. Pricing is not published. That describes limited real use, not general availability, established commercial maturity or a savings guarantee.
The responsible way to evaluate it is to use a known cut list and stock, review the pattern and compare it with the real process before running a series.
