Why Glass Cutting Needs Optimization
Glass is one of the most unforgiving materials to cut. Unlike wood, you cannot glue offcuts back together. Every wasted piece is a direct cost. For a glazier cutting 8 window panes from a single sheet of float glass, poor planning can waste 25-35% of the material.
Glass cutting optimization solves this by computing the exact layout of each cut. The optimizer considers the sheet size, all required pieces, the scoring tool kerf, and whether parts can be rotated. The result is a precise cutting map that maximizes yield from each sheet.
For commercial glaziers working with large orders (50+ window panes), optimization can save hundreds of dollars per project. For residential jobs, it means fewer sheets to order and less waste to dispose of.
Glass Cutting Tips for Better Results
Set Low Kerf for Score-and-Snap
Glass cutting with a manual score-and-snap method has minimal kerf (~0.5mm). Set this in the optimizer for accurate utilization calculations.
Consider Glass Grain
Some glass (especially textured or patterned glass) has a directional pattern. Disable rotation if the pattern needs to run in a specific direction.
Account for Edgework
If edges need polishing, beveling, or safety rounding, add 2-3mm to each side of the part. This ensures the final piece is the correct size after finishing.
Plan for Breakout
When cutting multiple pieces from a sheet, plan the cut sequence to avoid small, fragile pieces breaking during cutting. The optimizer cut order helps with this.
