Why is a blade kerf important?

The kerf is the thickness of the material turned to dust by the saw. Ignoring it means every subsequent piece cut will be progressively smaller than intended.

What is an end allowance?

An end allowance is extra trim material removed from the rough factory edges of stock to ensure a perfectly square starting edge.

How can I reduce waste on multiple jobs?

Batch the materials. Input all parts from job A and job B into a cut list optimizer at the same time to allow for better mathematical interlocking.

Should I keep all offcuts?

No, set a minimum offcut threshold (e.g., 500x500mm). Anything smaller takes up space and is rarely reused efficiently.

Do these practices apply to roll materials?

Yes, roll materials face the same issues. Using a roll cutting optimizer helps nest signs and prints to save continuous vinyl or fabric.

Material Cutting Best Practices — Comprehensive Guide for All Materials

Whether you work with plywood sheets, steel bars, or vinyl rolls, these universal best practices will lower your scrap rate and improve your workshop efficiency.

Apply Practices in Software

The Core 4 Best Practices

Practice 1: Plan Before You Cut. The old adage "measure twice, cut once" has evolved. Today, it means planning digitally before putting a blade to the material. Using a cut list software avoids irreversible common cutting layout mistakes.
Practice 2: Account for All Waste Factors. Never assume a 2440mm sheet yields exactly two 1220mm pieces. You must account for blade kerf, factory edge trimming, and damaged corners.
Practice 3: Track Your Inventory. Know exactly what full stock and usable offcuts you have on hand. Reusing offcuts is the fastest way to drop material costs.
Practice 4: Batch Similar Jobs. The more parts an algorithm has to work with, the better the yield. Combine jobs of the same material into a single cut list optimizer run.

Material-Specific Tips

For Sheet Materials (2D)

When working with panels, align your largest pieces first and allow software to pack small parts into the remaining voids to reduce sheet material waste. Learn more on our sheet cutting optimizer page.

For Linear Materials (1D)

When cutting timber lengths or aluminum extrusions, group offcuts effectively so you aren't left with dozens of useless 200mm scraps. Check out the length cutting optimizer tool.

For Roll Materials

Roll materials like vinyl and fabric have a fixed width and infinite length. Position cuts to minimize the drop (length) used. Use a roll cutting optimizer for print and signage.
