Glossary Of Laser Engraving and Cut Terms
[1] |
Sag In laser engraving, sag refers to the deformation or downward bending of a workpiece or material due to gravitational force or other external factors. Sag can occur when a workpiece is not adequately supported or when it undergoes thermal expansion or contraction during the engraving process. Minimizing sag is crucial for achieving uniform engraving depth and maintaining dimensional accuracy across the workpiece surface. Techniques such as proper workpiece fixation, support structures, and engraving strategies can help mitigate sag and ensure consistent engraving results, particularly when working with thin or flexible materials susceptible to deformation. |
