| Abstract | ||||
| The design of chasing cam is necessary due to continuous development of thread cutting.The machine productivity will be determined according the speed of the cam and the number of passes. The cam speed is often limited by the inertia forces. Therefore, it is imperative to choose the cam profile (motion program) with minimum acceleration. This work presents an analysis for various profiles. Six family of curves are deduced,namely; Constant acceleration, Harmonic, Cycloidal, Cubic, Polynomial, and Elliptical. The develpment of numerical controlled machines as well as digital computers requires the combination curve having the optimal value which ensures minimum acceleration. It is hoped that the proposed combination curves can be a useful aid in the field of chasing cam design. | ||||
