What is the cutting stock problem?

It's a classic algorithmic problem in computer science focused on cutting standard-sized pieces to minimize waste.

What is a First-Fit Decreasing algorithm?

An approach that sorts required cuts from largest to smallest, fitting them into the first available space.

Why can't I just calculate the optimal layout manually?

Because the number of possible combinations grows exponentially. Even 10 parts can have millions of permutations.

How does CutWize prioritize offcuts?

Our multi-phase engine specifically targets existing usable offcuts before cutting into fresh, full-length stock.

Does kerf thickness affect the algorithm?

Significantly. The software must add the blade width to every cut dimension to ensure mathematical accuracy.

The Science Behind Cut List Optimization

Under the hood of every great cutting plan lies the classic 'cutting stock problem' of computer science. Discover how CutWize leverages algorithmic bin-packing to outsmart manual calculations.

The Bin Packing Problem

At its core, calculating the best way to extract smaller shapes from a larger piece of material is a variant of the algorithmic 'Bin Packing Problem'. In computer science, this is considered an NP-hard problem. This means that as the number of required parts increases, the number of possible layout combinations explodes exponentially.

A human planner might try a dozen combinations on paper. A cut list optimizer evaluates thousands or millions in milliseconds.

The CutWize Multi-Phase Engine

CutWize goes beyond simple First-Fit Decreasing logic by employing a sophisticated multi-phase approach designed for real-world workshops:

Phase 0 (Pinned Cuts): Processes user-forced cuts that absolutely must come from a specific piece of stock.
Phase 1 (Existing Offcuts): Algorithm targets your saved, reusable remnants first, clearing out warehouse inventory.
Phase 2 (Available Random Stock): Utilizes non-standard available stock.
Phase 3 (Full Length Stock): Finally dips into the pristine full-sheet/full-length inventory, packing it as densely as mathematically possible.

Handling Variables like Kerf and Grain

A purely theoretical mathematical algorithm fails in a real workshop. Practical optimization must respect blade kerf (the thickness of the cut), part rotation restrictions (wood grain direction), and trimming margins.
