How a Cutlist Optimizer works
A cutlist optimizer answers one question. Given the parts you need and the stock you have, where should the cuts go? A cabinet shop, a metal fabricator and a site contractor are all asking it, and answering it by hand costs either material or time, usually both.
Core Functionality of Cutlist Optimizers
Section titled “Core Functionality of Cutlist Optimizers”Give the software a parts list and a stock list and four things happen, in order.
-
You enter the dimensions of the parts you need and the stock you have available, whether that is sheet sizes, board lengths or roll widths.
-
The software works through thousands or even millions of possible arrangements, comparing each layout to find the one that wastes the least material.
-
It produces a cutting diagram showing where every part sits on the raw material. For wood that includes grain direction. Other materials bring constraints of their own.
-
It gives the order of the cuts as well as their positions. That order is what keeps the cuts accurate, and what stops you reaching a point where the remaining cuts cannot safely be made.
The search behind step two is a version of two-dimensional bin packing, and the methods used to do it are covered in approaches to the bin packing problem.
Advanced Features and Considerations
Section titled “Advanced Features and Considerations”Past plain rectangular nesting, most current optimizers handle a few things that come from the workshop rather than from the mathematics.
Material accounts for much of it. Wood optimizers respect grain direction, for strength and for appearance. Metal optimizers account for heat-affected zones. Fabric optimizers deal with pattern matching. You can usually mark unusable areas on a sheet as well, knots or scratches or damaged sections, and the layout will work around them.
The rest comes from the machine. Blade thickness, minimum spacing between parts and the limits of the saw itself all feed into the layout, because a plan that ignores them is not cuttable. Offcuts from earlier jobs can generally be added back to the stock list and used in new plans.
Environmental and Cost Impact
Section titled “Environmental and Cost Impact”Most shops report 10-15% material savings after moving to optimization software, and some report 20% or more. Where material is half the cost of a project, that comes straight off the job. The waste side is the same figure read differently: fewer trees felled, less metal mined and less going to landfill, which is something customers now ask about.
Output and Analytics
Section titled “Output and Analytics”The output is more than the cutting diagram. Most tools also give you:
- Detailed part lists with dimensions and quantities
- Material usage summaries showing exactly what you’ll need to buy
- Waste percentages to track efficiency over time
- Cut sequences optimized for your specific equipment
- Labels and barcodes for part tracking through production
Some will also compare material options for you, so you can see whether a premium sheet with less waste works out cheaper than a budget one with more scrap.
Industry Applications
Section titled “Industry Applications”The same software gets used quite differently from one trade to the next.
Cabinet makers and furniture builders are mostly protecting expensive hardwood. They need grain direction respected and solid stock kept in step with sheet goods. Metal fabricators nest for plasma, laser and waterjet, where the cut itself takes time and the layout decides how much. Plastics work turns on the price of engineered material more than on the cutting. On site, contractors run everything from drywall layouts to structural steel through an optimizer, and the saving there is in skip hire as much as in material.
Future Trends and Developments
Section titled “Future Trends and Developments”Computing power and better algorithms keep moving this along. Machine learning is being used to read a shop’s cutting history and set sensible defaults from it. Cloud systems make the same optimization available across several locations at once. Integration with design software means the layout can be produced as soon as a design is signed off, which removes the export step rather than making it quicker.
Nesting software began as a way to avoid drawing layouts on paper. It sits closer to production planning now, because the cutting diagram, the material order and the labels all come out of the same file. For most shops that is worth more than the percentage on the waste report.
Common Questions
Section titled “Common Questions”Is cut list optimization worth it?
Section titled “Is cut list optimization worth it?”For anyone cutting sheet or linear stock regularly, yes, and the arithmetic is short. Most shops report 10-15% material savings after moving to optimization software, and material is often half the cost of a job. A free optimizer that saves one sheet on a single project has already paid for the ten minutes it took to learn. The cases where it is not worth it are genuinely small ones: a handful of cuts on one board can be laid out by eye.
What is a cut optimizer used for?
Section titled “What is a cut optimizer used for?”Three things: deciding how many boards or sheets to buy, laying out each cut so waste ends up as usable offcuts rather than slivers, and producing the cutting diagram the person at the saw works from. Shops also use the same output for quoting, since the material count is the largest number in the price.
What software do woodworkers use for cut lists?
Section titled “What software do woodworkers use for cut lists?”A cut list optimizer. Cutlist Evolution is free to use in the browser for sheet and linear stock, and imports parts from spreadsheets or directly from Fusion 360 and Shapr3D models.
