RailChop vs. Spreadsheet
Why cut optimization software beats manual planning — and when a spreadsheet is still enough.
The Spreadsheet Approach
Most framers still use a spreadsheet, or no tool at all—just mental math and a notepad. It works for the simple cases. You list your cuts, sort them by size, manually figure out what fits on each stick, and hope you didn't miss a kerf calculation. For 5 or 6 cuts on a single profile, this is fine. The combinations are small enough that you can visualize them.
But spreadsheets fall apart. Imagine 20 cuts from three different profiles, with mixed stock lengths and a half-dozen remnants on the rack. Now you're flipping between sheets, cross-referencing stock costs, manually trying different arrangements, recalculating kerf each time you move a cut. What takes 15–20 minutes for a competent human is error-prone, and there's no feedback loop—you never know if the plan you landed on is actually the best one.
Where Manual Planning Breaks Down
The real complexity isn't one order. It's this:
- Multiple orders sharing the same profile. A 16×20 frame and a 12×18 frame both use the same walnut moulding. On the same stick or different sticks? Depends on the arrangement.
- Mixed stock lengths with different costs. You have 16-foot and 12-foot sticks in inventory, priced differently. Which one should you use first?
- Remnants on the rack. Last week you cut a frame and left a 6-foot piece. Will it work for today's order? Maybe. Or maybe it's forgotten on the rack and you buy fresh material anyway.
- Kerf stacking across many cuts. Easy to miscalculate. A 0.125-inch kerf between every cut on a stick adds up fast.
- Quantities multiplying the combinatorics. If an order calls for 3 frames of the same size, you're managing 12 cuts instead of 4. The problem space explodes.
- Time pressure on the shop floor. You're looking at a work order while you're busy. You need a plan in 60 seconds, not 20 minutes.
- No feedback loop. You finish the day and have no idea what your actual waste was. Did the plan work out? Did you miss an opportunity? You'll never know.
What Changes with an Optimizer
With RailChop, the outcome is different. You scan or enter your orders. The system calculates the optimal arrangement in under a second. Fewer sticks used. Remnants integrated automatically. Each plan accounts for kerf, stock costs, and available remnants.
The time savings alone is significant—a plan that would take 15–20 minutes to hand-calculate comes back instantly. But the real win is accuracy. Kerf is calculated precisely, not estimated. Stock lengths are checked automatically. Remnants are tracked so nothing sits forgotten on your rack.
The formula is straightforward, but optimizing across dozens of cuts, multiple profiles, and different stock lengths means weighing far more arrangements than anyone can sort by hand in the time you have between jobs. An optimizer can.
Integration is the other advantage. Instead of managing remnants manually—wondering if that 6-foot offcut from last week is still good—the next batch pulls it automatically if it fits. Offcuts feed back into future plans instead of sitting forgotten on the rack or thrown away.
And tracking changes everything. Your shop dashboard shows waste trends so you can measure improvement over time. Is your optimization holding? Are certain profiles harder to batch? You'll know.
The Real Cost of Not Optimizing
Industry discussions and our own early-testing observations put manual moulding waste in the 15–25% range. Shops that batch orders by profile, integrate remnants, and use a dedicated optimizer typically land in the 8–12% range. These aren't formal industry-wide benchmarks — but the gap is consistent across sources, and most shops we've talked to land somewhere in that spread.
What that gap is worth depends on your shop. The bigger your monthly moulding spend, the more a few percentage points of recovered material adds up. Our waste calculator can help you put a real number on it for your shop.
This assumes you're doing enough volume to benefit. If you're cutting 2–3 frames a day from one profile, you probably don't need it.
Who Should Stay with a Spreadsheet
Let's be honest: if you do 2–3 frames a day from the same profile, a spreadsheet is genuinely enough. The math is simple, your waste is probably acceptable, and the overhead of learning new software isn't worth it.
RailChop is built for shops running 10+ jobs per day across multiple profiles—where the math gets complex enough that manual planning leaves money on the table. It's for shops where orders have different quantities, different mouldings, and time pressure on the shop floor. It's for shops that want to know, at the end of the month, whether they're getting better or worse.
If that's you, the spreadsheet era is over. The problem is too big for a person in a chair with a calculator.
