PMMA Laser Cutting Heat Affect
Fenómeno del problema
A heat-affected zone appears on laser-cut edges, with transparent edges whitening and slightly melting
Análisis de la causa
Laser energy locally melts and resolidifies the cut surface, forming a heat-affected zone; when power and speed do not match, edge whitening and micro-melt beads are obvious, affecting optical parts; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
①Optimize the matching of laser power and speed; ②leave machining allowance on optical edges and polish afterward; ③switch high-requirement parts to CNC or waterjet cutting; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
Conclusión clave
Laser cutting is fast but has a thermal cost; optical edges are remedied with allowance plus polishing, or simply switch to cold machining processes; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
