Case Studies / Material Removal / Auto Bumpers

Motoman Robot Laser CuttingAchieved 27.5 second cycle time — 0.5 seconds faster than requirement. Met customer’s requirements for cutting tolerances. Bumpers produced meet end-customer’s stringent strength and quality requirements for crash performance.

Project Challenges

  • Provide flexibility to process several styles of automotive front bumpers.
  • Cut 8 circles and 4 slots (12 total) precise holes in 3-mm (0.118") thick galvanized steel front bumpers.
  • Achieve cutting tolerances of ±2-mm (±0.079"). Achieve cycle time of 28 seconds per part.
  • Meet customer’s production rate of 1,400 parts per day based on two 7-hour shifts.
  • Bumpers must meet end-customer’s stringent strength and quality requirements for crash performance.
