How to Optimize Plywood Cutting

Start with an accurate cut list

List every part with its finished width, length, quantity, and grain requirement. Accuracy here is everything: a wrong dimension cascades into wrong layouts and wrong sheet counts. Importing the list from a spreadsheet avoids transcription errors.

Respect grain direction

Visible plywood parts — cabinet sides, doors, drawer fronts — usually need the face grain running a specific way. Lock grain direction for those parts so the optimizer does not rotate them, even though rotation would save material. Hidden parts can usually rotate freely.

Set the right kerf and trim

• Enter your saw blade kerf (commonly 3 mm) so parts stay on dimension.
• Add a trim allowance to remove the factory edge if your sheets arrive damaged.
• Account for any oversize cut you plan to clean up later.

Let the optimizer do the packing

With parts, grain, and kerf defined, the optimizer arranges everything across the minimum number of sheets and produces a labeled cutting diagram. You then cut following the diagram, confident that the parts will fit and the grain will be correct.

Cut smart at the saw

Make the long rip cuts first to break the sheet into manageable strips, then cross-cut to final size. Following the optimized diagram in this order keeps handling safe and accurate, especially with full sheets.
