The procedure of changing the length of cutting stroke of quick return mechanism.
Explanation:
A quick return mechanism is an apparatus to produce a reciprocating motion in which the time taken for travel in return stroke is less than in the forward stroke. it is driven by a circular motion source and uses a system of links with three turning pairs and a sliding pair. quick return of is a common feature of tools in which the action is performed in only one direction of the stroke, such as shapers and powered saws, because it allows less time to be spent on returning the tool to its initial position.
