Glossary Of Laser Engraving and Cut Terms [1]

Thermal Stress Thermal stress refers to the mechanical stress induced in materials as a result of uneven temperature distribution or thermal gradients within the material. In laser engraving and cutting processes, thermal stress can occur when the laser beam heats the material rapidly, causing localized expansion and contraction. Thermal stress can lead to undesirable effects such as material warping, cracking, or distortion, particularly in materials with high thermal conductivity or low melting points.

Minimizing thermal stress is essential for achieving precise and consistent engraving results, especially in applications where dimensional accuracy and material integrity are critical. Proper selection of laser parameters, such as power, speed, and focus, along with material-specific techniques and cooling strategies, helps mitigate thermal stress and ensures high-quality engraving outcomes.
