Glass cutting
optimization software
Float glass, tempered glass, mirrors, laminated glass — precise cutting plans with minimal waste, free and in your browser.
Start optimizingWhy is glass cutting waste so costly?
Glass is expensive, and the risk of breakage makes waste minimization critical. Poorly planned cuts can result in up to 30% waste, not counting breakage losses.
How does CutOptim minimize glass waste?
CutOptim is glass cutting optimization software that runs in the browser — nothing to install, and no account needed to try it. Its guillotine cutting algorithm ensures every cut runs in a straight line from edge to edge, exactly as glass cutting physically requires, and kerf can be set to 0 mm for score-and-snap work.
Industry at a glance
Guillotine cuts
Only straight, through-cuts — the only physically possible method for glass.
Zero kerf
Set 0mm blade kerf for score-and-snap glass cutting.
Visual verification
SVG visualization for every stock sheet — see the cutting plan instantly.
Common use cases
Real-world scenarios where cutting optimization makes the biggest difference.
Window panels
Cutting IGU (Insulated Glass Unit) panes for residential and commercial windows. Multiple identical sizes grouped for batch processing.
Shower enclosures
Custom shower screens require precise dimensions. Tempered glass cannot be cut after treatment — optimize before tempering.
Mirrors
Bathroom mirrors, wardrobe doors, and decorative mirrors from mirrored float glass. Standard sheet sizes vary by supplier.
Glass railings & balustrades
Structural glass balustrades for balconies and staircases. Exact tolerances required for hardware fittings.
A glass workshop cuts 32 different-sized tempered glass panels from 6mm float glass for office partitions.
Common glass types and sizes
| Material | Standard sizes | Kerf | Tip |
|---|---|---|---|
| Float glass (clear) | 3210×2250, 3210×2550, 6000×3210 mm | 0 mm (score-and-snap) | Set kerf to 0mm — glass is scored and snapped, not sawed |
| Tempered (toughened) glass | Cut from float BEFORE tempering | 0 mm | Cannot be cut after tempering — optimize and cut from float first |
| Laminated glass | 3210×2250, 3210×2550 mm | 2–3 mm (diamond wheel) | Laminated glass requires diamond wheel cutting — set appropriate kerf |
| Mirror glass | 2550×1605, 3210×2250 mm | 0 mm | Cut from the glass side (not mirror side). Score-and-snap method. |
Automate it — the Engine API
Glass is scored and snapped edge to edge — a 2D guillotine problem the engine solves exactly, and the same engine is available over HTTP. Your software sends the panels and the stock sheets as JSON and gets back a guillotine-valid cut plan, the yield, and an inline SVG drawing for the cutting table.
- ✓Every plan is guillotine-valid — the straight edge-to-edge cuts a glass table can actually make.
- ✓Ask for include: ["svg"] and the layout comes back as a drawing inline in the response.
- ✓Free validation: POST /v1/validate/2d checks a job with no key and no quota.
