Description: A designed experiment was performed on the staking operation of a miniature precision bearing. Three variables were controlled during the experiment: staking force, tool diameter, and bearing-to-wheel fit. The study showed that the current staking tool diameter is highly sensitive to staking force and to bearing-to-wheel fit, whereas a smaller diameter tool is not. The study also shows that, with the current process, bearing movement under a 100-Newton (N) force can be estimated at 0.009 in. to 0.0029 in. The current specification is 0.002 in. and should be revised to 0.0035 in. 4 figs.
