WebGeneral Kinematic Quick Return Background: The kinematic quick return device is a mechanism typically containing either four or six linkages. Either configuration accomplishes a repeating pattern with a faster return stroke and slower forward stroke. The length of each stroke corresponds to an arc of the crank length, with the boundaries being WebAnswer (1 of 5): In the forward stroke , cutting action takes place. Certain time is spent in cutting operation depending upon strength of material, speed , feed, depth of cut etc. On the return stroke, there is no cutting action. Hence, it returns back to its starting position. Therefore, it is ...
