The Core Problem
Picture framers face a daily optimization challenge: you have sticks of fixed lengths and customer orders with cuts of various sizes. The goal is to fit those cuts across the fewest sticks possible, leaving as little waste as possible. It's a classic puzzle that shows up anywhere material gets cut to order — manufacturing, lumber yards, and any framing shop with more than a handful of jobs in a day.
The challenge is that there's no single "perfect" way to arrange the cuts. Different sequences, different stock combinations, and different remnant choices all produce different results. A basic plan might get lucky on a given order. But a smart plan — one that weighs all the variables at once, across every order — compounds savings that manual cutting can't match. Industry discussions and our own early-testing observations consistently put manual moulding waste in the 15–25% range, with optimized shops landing closer to 8–12%. The exact gap depends on your shop's volume, current discipline, and frame-size mix.
What Makes a Good Optimizer
Accuracy with kerf. Kerf is the width of material lost to each saw blade cut. Industry standard is 0.125" (1/8"). It compounds across every cut on a stick — a long batch with dozens of cuts loses real material to kerf alone. A naive optimizer that ignores kerf will produce cut lists that don't fit. Get it right, and your waste calculation is accurate to the shop floor.
Mixed stock awareness. Most shops cut from fresh stock, but also maintain a supply of remnants — shorter pieces from previous jobs. A good optimizer knows what's on the rack and what's in the stockroom, and produces a plan that accounts for both. The result is fewer fresh sticks pulled and less dead inventory sitting around. Remnant integration is one of the biggest levers — it turns forgotten offcuts into productive material and reduces how much new moulding you need to order. See how remnant tracking works in practice.
Cost awareness. Not all waste is equal. A 12" scrap of $8/foot moulding is worth more than a 12" scrap of $2/foot moulding. A good optimizer treats moulding cost as part of the picture, not just stick count, so the plan it returns reflects the real economics of what's on your rack and in your stockroom.
Speed on the shop floor. A cutting plan that takes 30 seconds to generate is useless if it would save $0.30 per order. A good optimizer must run instantly on standard hardware, return results while you're reviewing the job, and not add friction to your workflow.
RailChop's Approach
RailChop uses a proprietary algorithm designed specifically for picture framing. It handles kerf, mixed stock lengths, remnants, and cost — all the variables a framer deals with daily — and returns a single best plan. No parameters to tune, no modes to choose between. You tap Optimize and get a result in under a second.
The details of how the algorithm works are proprietary, but the outcome is straightforward: plans that consistently use fewer sticks and produce less waste than manual cutting. It runs on your device, works offline, and doesn't add friction to your workflow. You review the cut list, tap a button, and get a plan you can take straight to the saw.
The Real ROI
The savings depend on your shop's volume and current waste rate. The bigger your monthly moulding spend, the more even a few recovered percentage points add up. A higher-volume shop will see the math compound faster than a low-volume one. The waste calculator can help you put a real number on it for your shop.
The key is that the gains come from the full workflow, not any single feature. The optimizer alone is a meaningful improvement over manual cutting. But when you combine it with mixed stock lengths that give the algorithm more options, remnants that feed back into future plans, and profile batching that eliminates unnecessary setup waste — that's where waste rates really drop. Add in time savings from eliminating handwritten cut lists — whether you scan work orders or import cut lists from a spreadsheet — and reduced errors from manual math, and the payback shows up quickly for most working shops.
