Improved productivity two or three times over existing gantry systems that run one type of part and require manual changeover. Cycle time: 26 seconds on test part.

Project Challenges

  • Process eight different part combinations (six different sizes) with right hand (RH) and left hand (LH) part configurations, plus LH/LH and RH/RH only configurations for one part size.
  • Provide flexible tooling/fixtures to handle multiple part sizes and shapes without manual change over or interruption in cycle.
  • Achieve cycle time of less than 30 seconds per set.
  • Achieve repeatability of ± 0.5 mm (.02").
  • Improve productivity and flexibility over existing gantry systems that process only one part size and configuration at a time and require manual changeover.
  • Minimizing need for operators to work in a fume-filled environment.
