Free particle board cut optimizer

What a particle board cut optimizer does

A particle board cut optimizer takes the list of parts you need (their length, width and quantity) and works out how to lay them out on full panels with as little waste as possible. Instead of guessing, you get a numbered cutting plan, a clear cut list, and the exact number of sheets to buy. cutlistlab does this entirely in your browser: there is nothing to install and no account needed. Particle board (chipboard) is the cheap budget sheet, so a tight layout keeps your costs down and your offcut pile small.

How to use it

1. Enter your parts. Add each part with its length, width and quantity. Give parts a name so they are easy to match later.
2. Pick your particle board panel. Choose a standard 4x8 ft (1220x2440 mm) sheet, a metric 2440x1220 mm panel, or enter your own size. Add offcuts you already have so they get used first.
3. Set the kerf. Enter the width your saw blade removes per cut so the parts come out exactly to size.
4. Read the plan. The optimizer packs everything onto the fewest sheets, shows the layout as a drawing, lists the cuts in order, and tells you how many sheets you need and how much is left over.

Why it cuts waste on particle board

Particle board is the budget option, so the cost saving comes from buying fewer panels and wasting fewer offcuts. The optimizer tries several packing strategies and keeps the best result, which usually beats laying parts out by hand. A few things matter on particle board specifically:

• Free rotation. Plain chipboard has no grain, so every part can rotate to pack tighter. If you use a faced (melamine) panel with a directional pattern, you can lock that part's orientation instead.
• Cleaner cuts at the edges. The chip core crumbles and chips easily, especially on a faced panel. Fewer, well placed cuts mean fewer rough edges, so the optimizer's tidy layout is also a kinder one for the material.
• Offcuts as stock. Particle board is cheap but bulky to store. Add leftover panels from earlier projects and the optimizer uses them before cutting into a fresh sheet.
• Kerf and trim. The blade width and any edge you trim off a rough sheet are included, so the plan is realistic, not just theoretical.

One thing to keep in mind: particle board is not as strong as plywood and it swells when it gets wet, so it suits dry, indoor work and shelving that will not carry heavy loads. The optimizer handles the cutting plan; choosing the right panel for the job is still up to you.

A worked example

As an example, say you are cutting the parts for a simple particle board garage storage cabinet from one 2440 × 1220 × 18 mm sheet.

Particle board has no grain, so cutlistlab is free to rotate parts and, with a 3 mm kerf, packs these onto about 1 sheet, leaving roughly 35% as usable offcut for your offcut stock. You optimise for least waste, fewest cuts or lowest cost, and you get a numbered cutting order to follow at home or hand to the builders' merchant.
