Automotive Precision Laser Cutting
Robotic 3D laser trimming for hot-stamped ultra-high-strength steel: A-pillars, B-pillars, door rings and structural body reinforcements. FANUC accuracy maintained across two-shift production.
Ultra-high-strength hot-stamped steel destroys conventional trim dies within weeks. Die replacement cost and unplanned downtime directly erodes per-part margins on body-in-white components.
Thermal variation across shifts causes tolerance creep on safety-critical A-pillar and B-pillar trim lines — requiring frequent recalibration that halts production runs.
Automotive body flanges and compound curves cannot be programmed at the teach pendant. CAD-to-path offline simulation is essential for consistent cut quality at production speed.
FANUC M-20iD/12L with ROBOGUIDE offline programming from CAD step files. Zero tooling cost, zero die maintenance. ±0.12mm tolerance over two-shift production. One cell replaces multiple press tool die sets.
"18 months in production, holding ±0.12mm with zero recalibration. Four trim dies retired. ROI was clear within the first quarter."
