Return stroke of the shaper is called which of the following

  • A.Cutting stroke
  • B.Idle stroke
  • C.Static stroke
  • D.Dynamic stroke

Answer: B

The return stroke is the Idle stroke.

On a shaper the tool cuts only on the forward stroke. On the return stroke it is lifted clear by the clapper box and does no cutting, so the stroke is idle, wasted time that the quick return mechanism shortens.

The cutting stroke is the forward stroke, the opposite of the return. 'Static' and 'dynamic' stroke are not terms used for shaper strokes.
