%X The application of Formed-In-Place Gasket (FIPG) using a robotic machine  requires appropriate process parameter settings to produce a consistent sealant bead  diameter within the specified limits. Improper parameter settings can cause  diameter variation, increase the risk of process failure, and lead to material waste  during machine setup. This study aims to identify the effects of pump pressure,  robot speed, and nozzle height on sealant bead diameter, determine the optimum  combination of process parameters, and evaluate process capability under the  optimum conditions. The Taguchi method with an L9 Orthogonal Array was  employed using the Nominal is Best quality characteristic. The experiment used  sealant with a viscosity of 75 Pa.s and an SNA-15G nozzle with an internal diameter  of 1.43 mm. The investigated factors consisted of pump pressures of 0.1, 0.2, and  0.3 MPa; robot speeds of 50, 75, and 100 mm/s; and nozzle heights of 1, 1.5, and 2  mm. The Signal-to-Noise Ratio analysis showed that pressure was the most  dominant factor, with a delta value of 12.047, followed by nozzle height at 7.641  and robot speed at 7.101. Based on the means analysis, pressure was also the most  dominant factor, with an ANOVA contribution of 53.48%. The optimum process  parameter combination was obtained at a pressure of 0.1 MPa, a robot speed of 100  mm/s, and a nozzle height of 2 mm, with a predicted S/N Ratio of 23.5566 and a  predicted mean bead diameter of 1.11847 mm. Furthermore, process capability  analysis under the optimum conditions resulted in a Cp value of 3.95 and a Cpk  value of 2.28, indicating that the process has a very high capability to meet the  specified limits. The results demonstrate that the Taguchi method can be used to  determine an optimum combination of process parameters, while process capability  analysis can be used to evaluate the stability and capability of the robotic sealant  application process.
