A 6,000 mm bar is not always the same resource
In many metal workshops, six-metre bars are the usual commercial reference. The stockroom also contains remnants from previous jobs, set-aside pieces and lengths that no longer match the nominal size. Treating everything as one pool hides opportunities and may open a new bar unnecessarily.
Start by recording every length with an identifier. Separate full bars, usable remnants and pieces that need checking before production. The cutting plan must know what it can use and what needs verification.
Calculate the remnant with kerf included
The remainder after a sequence of cuts is not the simple subtraction of bar length and pieces. Each separation consumes kerf and angles can alter effective length. In 6,000 mm bars, a few repeated millimetres can decide whether a piece fits or moves to the next pattern.
Distinguish waste from remnant. Waste has no reasonable use; a remnant can be stored and considered again. The threshold depends on the workshop’s usual pieces, but it must be an explicit decision.
Use the remnants that solve the job first
When a remnant is long enough for a piece, using it can free a commercial bar for another combination. Always using the shortest remnant is not necessarily best: it may consume a useful length and leave a full bar underused. Look at the whole cut list, not only the next cut.
A visual plan makes patterns comparable before material moves. If every bar shows its pieces, remnant and reference, the office can review the decision and the workshop can find the right material.
Keep remnants that can return to the process
A useful remnant needs a minimum identity: material, section, approximate length and, when relevant, finish or batch. Without it, the remnant exists physically but cannot be found when needed. A reference and readable measurement are enough to begin.
Define when a remnant stops being worthwhile. A piece too short for usual work occupies space and adds decisions. The goal is not to keep every millimetre, but material with a real chance of re-entering a plan.
Turn planning into a clear order
The optimisation only adds value when the order reaches the workshop complete. Each bar should show pieces, pattern or sequence, measurements, kerf and expected remnant. When material leaves stock, the operator must quickly confirm that the selected bar matches the plan.
Corte 1D turns commercial lengths and remnants into a reviewable plan. Start from an existing cut list, compare bar usage and give office and workshop one shared reference. The result does not replace a material check; it makes that check easier before cutting.
