Common cutting (also called shared-edge or common-line cutting) places parts so that adjacent straight edges lie on the same cut line. Instead of cutting two parallel edges with a gap between them, the machine makes one cut that serves both parts.

​
Why use it

  • Less waste — the material that would sit between two parts is removed.
  • Faster cutting — fewer total cut lengths and fewer pierces.
  • Denser nests — parts pack tighter on the sheet.

​
Trade-offs

  • Requires straight, matching edges to align — not every part pair qualifies.
  • Shared cuts can affect edge quality and part separation, so it suits some processes better than others.
  • It constrains placement, which the nester balances against overall utilisation.

​
Using it

Common cutting is controlled through the nesting settings in the request payload. Enable it when your process and parts suit shared edges; leave it off when edge quality or handling matters more than the material saving.
For the exact setting that toggles common cutting and any related tolerances, see the request models in the Nesting section of the API Reference.
