⚠️

Why 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's guillotine cutting algorithm ensures every cut runs in a straight line from edge to edge — exactly as glass cutting physically requires.

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.

MATERIAL Float glass 3210×2250mm, 4–6mm thick
SAVINGS Reduce stock sheet usage by 20–25%

Shower enclosures

Custom shower screens require precise dimensions. Tempered glass cannot be cut after treatment — optimize before tempering.

MATERIAL Clear float 3210×2250mm, 8–10mm (pre-tempering)
SAVINGS Save 1–2 stock sheets per batch of 10 showers

Mirrors

Bathroom mirrors, wardrobe doors, and decorative mirrors from mirrored float glass. Standard sheet sizes vary by supplier.

MATERIAL Silver-coated float 2550×1605mm, 4mm thick
SAVINGS Reduce waste from 25% to 10%

Glass railings & balustrades

Structural glass balustrades for balconies and staircases. Exact tolerances required for hardware fittings.

MATERIAL Laminated safety glass 3210×2250mm, 10+10mm
SAVINGS Optimize €800+ material per floor
📊 Real example: Office glass partitions

A glass workshop cuts 32 different-sized tempered glass panels from 6mm float glass for office partitions.

Before
Manual planning 12 stock sheets

After
CutOptim 9 stock sheets
Waste 11%

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.

Frequently asked questions

Why should I set kerf to 0mm for glass cutting? +
Unlike wood or metal, glass is cut by scoring a line on the surface and then snapping along that line. There is no material removed during the cut, so the blade kerf (cut width) is effectively 0mm.
Can CutOptim handle tempered glass projects? +
Yes, but remember that tempered glass must be cut from float glass BEFORE the tempering process. Use CutOptim to optimize the cutting plan from raw float glass stock sheets, then send the cut pieces for tempering.
How do I handle different glass thicknesses in one project? +
Create separate optimization runs for each thickness. CutOptim supports saving multiple cuts within a single project, each with its own stock size and settings.
Does CutOptim account for edge polishing? +
Edge polishing typically removes 1–2mm per edge. If your glass pieces require polished edges, add this allowance to each part dimension before optimization.
What is the minimum practical glass piece size? +
For score-and-snap cutting, the minimum practical size is about 50×50mm for 4mm glass and 100×100mm for thicker glass. Set the minimum offcut size in CutOptim to filter out unusable pieces.
📋 Case study: Glass workshop efficiency

A mid-sized glass workshop processing 50+ orders per week implemented CutOptim for their float glass cutting operations. Previously, operators arranged pieces manually on the glass table.

Result

Monthly glass waste decreased from 24% to 9%, saving over €1,500 per month on 6mm float glass alone. The visual SVG cutting plans reduced cutting errors from 3 per week to nearly zero.
