| Summary: | Abstract The production process needs spray painting particularly within automobile manufacturing since product painting accuracy establishes product quality. The combination of hand spray techniques produces intricate designs as well as small quantity needs yet industrial robots excel at painting large industrial product orders. Taguchi Design of Experiments (DoE) is used to investigate the effect of six process variables which included spray distance along with pressure, temperature, humidity level, speed and viscosity rate. Experiments were conducted via industrial robotic spraying with subsequent statistical evaluation through ANOVA tests and regression calculations. The research shows that viscosity together with temperature stands as primary influential factors for thickness deviation, yet speed and temperature jointly determine surface roughness outcomes. The predictive model performed with substantial accuracy based on its ability to achieve R² values of 0.9224for surface roughness measurements and 0.9707 for thickness variation determination. The study offers clear guidelines for practitioners to enhance their processes to produce high-quality products and time efficiency. |
