This paper presents an analytical and experimental investigation of engagement of parts aided by two orthogonal constant-amplitude sinusoidal motions in mechanical assembly. In the analytical investigation we analyze how the amplitudes, frequencies, frequency ratio, and phase angle of the two motions affect the engagement. A numerical technique is developed for selecting these parameters, and a parts engagement strategy capable of recognizing various failure situations in peg-in-hole assembly is developed. Experiments are conducted to verify the validity of the parts engagement strategy as well as to provide useful information about the characteristics of contact force during the engagement.
