What is Linear Cutting Optimization?
Linear cutting optimization, also known as 1D cutting optimization or 1D bin packing, is the process of grouping multiple short cut lengths into standard long stock pieces in the most mathematically efficient way. Every linear cut generates potential waste, which makes accurate calculation critical.
When a metal fabricator or timber framer needs hundreds of specific lengths cut from standard 6-meter bars, finding the best combination to minimize the leftover offcuts is incredibly complex. A linear cutting optimizer instantly processes these permutations, factoring in the thickness of the saw blade (kerf) and end-trim allowances.
Use our linear cutting calculator to automate this math. By implementing our optimisation software, workshops can calculate material use from their actual stock, cuts, kerf and reusable offcuts. You can discover more about these capabilities on our features page.
How CutWize Handles Linear Optimization
Our 1D linear optimizer is built specifically for high-volume workshops looking for precision and speed:
- Input Your Inventory into the Linear Cutting Optimizer: Enter your standard full-length bar sizes and any reusable offcuts sitting on your racks.
- Add Required Cuts: Import or type in your cut list, including quantities and job labels. You can even "pin" specific cuts to specific stock pieces if necessary.
- Configure Settings: Dial in your blade kerf thickness, universal rough-end trim allowances, and set priorities (e.g., forcing the system to consume offcuts before cutting into new stock).
- Multi-Phase Optimization: The algorithm runs a sophisticated first-fit decreasing routine to pack your cuts seamlessly into the available lengths.
- Print & Cut: Generate clear, visual cut lists that operators can follow logically, reducing mistakes at the drop saw.

Industries Utilizing Linear Optimization
- Aluminum Fabricators: Optimise window frames, door extrusions, and architectural tracks while planning raw material use.
- Timber Yards & Builders: Generate precise cut lists for framing lumber, decking boards, and structural beams.
- Steel & Metal Working: Plan steel tubes, angle iron, rebar, and solid bars using steel & aluminium cutting layouts, with kerf and reusable offcuts included in the planning workflow.
- Plumbing & HVAC: Efficiently cut PVC pipes, copper tubing, and conduit for large commercial installations.
- Manufacturing: Streamline production lines that process any rolled or extruded 1D materials and accurately calculate project material usage.
Why Replace Manual Cut Planning?
Relying on an operator with a tape measure and a spreadsheet can be slow and makes it harder to compare cutting combinations. Manual planning can leave awkward remainders that are difficult to reuse.
CutWize's linear cutting software looks at the entire job and groups compatible lengths together. It identifies reusable offcuts according to your settings, helping you plan material use more systematically. View our pricing to get started.
