Abstract

This paper deals with the problem of specifying motions for high-speed cam mechanisms where reduction of vibration is a ma- jor concern. It presents Bézier harmonic curves and C2 piecewise Bézier 3-harmonic curves for synthesizing cam-follower motions with low-harmonic content. As examples, these curves have been applied to the synthesis of Rise-Dwell-Return (RDR) cam mo- tion program to demonstrate the exibility and ease-of-use of the curves. It has also been shown that these curves have consider- ably lower harmonic contents than those of 3-4-5 polynomials at high frequencies. The results are useful for motion specifications of high-speed machinery including not only cam mechanisms but robot manipulators as well.
