Abstract


The cutting time ratio is one of the most important parameters pointing out the effectiveness of the Whitworth quick return mechanism. The study supplemented a novel modification to a traditional Whitworth quick return mechanism to improve the cutting time ratio. The alteration was performed by consolidating a set of links to the conventional mechanism. This supplemental encompasses a crank, a ground, a sliding pivot, and a slotted link. A mathematical model was derived for the modified Whitworth quick return mechanism. This mathematical model was used for simulation to check the enhancement of cutting time ratio due to the new additional links. It was shown that the increase in the value of cutting time ratio exceeds eight times that of the original mechanism. Taguchi and Analysis of Variance (ANOVA) methods were utilized to verify the effectiveness and weight of each additional link on the enhancement of cutting time ratio. The outcomes manifested that the added links and their joining to the ground are more influential than the original links.
