This article explains using the classic quality engineering method—Taguchi Method—to scientifically optimize robotic painting.
Core Idea
Using orthogonal arrays to find key factors and optimal levels affecting coating quality (uniformity, adhesion) with minimal experiments, reducing sensitivity to noise (environmental fluctuations).
Case Study: Optimizing Film Uniformity
For automotive plastic parts: sets control factors (speed, flow, distance) and noise, uses an L9 array, analyzes via S/N Ratio for the optimal combination, and validates the result.
The method systematically improves process robustness.
