The objective of this research is to find the appropriate parameter setting for wobble riveting with
design of experiment techniques. By designing experiments of 2k full factorial model to study factors
that affect the production process including air pressure, rivet pressure, time, and height. The response
values are Wobble High and DCR. In this study, 16 experiments were conducted and 2 experiments
were repeated. The results found that factors affecting the wobble high include air pressure, time, height
and interaction effects between air pressure and time, time and height and factors affecting electrical
resistance (DCR) are the rivet pressure, time, and height at the significance level of 0.05. With the
appropriate parameters to the production process are as follows: 2.5 bar air pressure, rivet pressure at level
of 6, time at the level of 6, height of 10.482 cm, and the total desirability function of 0.68313. The experiment was conducted to confirm the results by using parameter values derived from the analysis. The
experiment was repeated 3 times and the analysis of variance (ANOVA) of the response value of both
before and after improving parameter values. The results of average variance analysis of response are
significantly different. This shows that the response after improving parameter values is different from the
parameter values of current production and is within the range of product specification.
